in effect

C.R.S. § 37-87-101 Storage of water

37-87-101. Storage of water. (1) (a) The right to store water of a natural stream for later application to beneficial use is recognized as a right of appropriation in order of priority under the Colorado constitution. No water storage facility may be operated in such a manner as to cause material injury to the senior appropriative rights of others. Acquisition of those interests in real property reasonably necessary for the construction, maintenance, or operation of any water storage reservoir, together with inlet, outlet, or spillway structures or other facilities necessary to make such reservoir effective to accomplish the beneficial use or uses of water stored or to be stored therein, may be secured under the laws of eminent domain. (b) State agencies shall, to the maximum extent practicable, cooperate with persons desiring to acquire real property for water storage structures. (2) Underground aquifers are not reservoirs within the meaning of this section except to the extent such aquifers are filled by other than natural means with water to which the person filling such aquifer has a conditional or decreed right. (3) (a) Water attributable to a water right for which a previous change of water right has been judicially approved, that has been decreed for storage, and for which the historical consumptive use was previously quantified may be stored in any reservoir that is located on the same ditch or diversion system, including a nontributary aquifer if the requirements of subsection (2) of this section are complied with, as an alternate place of storage if: (I) The water that is to be stored at the alternate place of storage is diverted from a point of diversion that has already been decreed for that water right; (II) The owner or operator of the storage water right gives previous notice to the division engineer that identifies the water right, alternate place of storage, decreed point of diversion, and how the storage of the water in the alternate place of storage will be accounted for; (III) Transit and ditch losses, if applicable, are assessed against the water right from the decreed point of diversion to the alternate place of storage; and (IV) The division engineer has approved the accounting for the storage of the water in the alternate place of storage. (b) A person who is entitled to claim injury to a water right has the right to a de novo hearing before the water court to argue that an alternate place of storage injures the person's water right. (c) Nothing in this subsection (3) allows the storage of water in an alternate place of storage if that water was imported from another water division. (d) Other than the place of storage, all of the terms and conditions of the previous change of water right decree continue to apply to the water right.

C.R.S. § 37-87-102 Definitions - natural streams and use thereof by reservoir owners

37-87-102. Definitions - natural streams and use thereof by reservoir owners. (1) As used in this article, unless the context otherwise requires: (a) "Mean annual flood" means a flood which has a magnitude (peak discharge) which is expected to be equaled or exceeded on the average once every 2.33 years and has a forty-three percent chance of being equaled or exceeded (0.43 exceedance probability) during any year, by application of the criteria defined in subsection (2) of this section. (b) "Natural stream" means a place on the surface of the earth where water naturally flows regularly or intermittently with a perceptible current between observable banks, although the location of such banks may vary under different conditions. (c) "One-hundred-year flood" means a flood which has a magnitude (peak discharge) which is expected to be equaled or exceeded on the average once during any one-hundred-year period (recurrence interval) and has a one percent chance of being equaled or exceeded during any year (0.01 exceedance probability). The terms "one-hundred-year flood", "one percent chance flood", and "intermediate regional flood" are synonymous. (d) "One-hundred-year floodplain" means that area in and adjacent to a natural stream which is subject to flooding as a result of the occurrence of a one-hundred-year flood. (e) "Ordinary high watermark" of any stream means the visible channel of a natural watercourse within which water flows with sufficient frequency so as to preclude the erection or maintenance of man-made improvements without special provision for protection against flows of water in such channel or the channel defined by the mean annual flood, whichever is greater. (2) Whenever the records basic to a determination of probable future water flows, either with respect to this section or by other requirements of law, extend for a period of one hundred or more years, the calculation based upon those results shall be deemed conclusive. If such records do not extend for a period of one hundred or more years the determination shall be made by interpolation and correlation to a full one hundred years of records by relating them to known records of water basins as similar as reasonably possible to the basin under consideration or by other acceptable methods. (3) (a) In any case in which a determination of probable future surface water flows at any place in the state is required, the calculation shall be based upon past surface water runoff at the place in question supplemented as provided in this section. Such probable flows shall be determined by reference to the records of reliable stream gauging stations. A stream gauging station record shall be deemed reliable if made by the state of Colorado or the United States as part of a regular program of either of those entities, except as to any part of such records which the state engineer shall have designated as being unreliable, on the basis of facts so showing. Whenever a designation of probable future runoff is required at a place other than the location of a reliable stream gauging station, the determination of probable runoff at such other place shall be made by relating the probable future runoff at that place to the recorded runoff at a comparable gauging station or gauging stations by the interpolation of reasonable hydrologic, geologic, and natural vegetative factors supplemented as provided in this section. Unless clearly unrelated, the factors of the comparison shall include, but not be limited to, the following elements or characteristics: (I) The water basin contributing to the probable future flow at the place where probable future runoff is to be determined, considering: (A) The size; (B) The altitude or altitudes; (C) The various soil permeabilities; (D) The various vegetative covers; ion. Unless clearly unrelated, the factors of the comparison shall include, but not be limited to, the following elements or characteristics: (I) The water basin contributing to the probable future flow at the place where probable future runoff is to be determined, considering: (A) The size; (B) The altitude or altitudes; (C) The various soil permeabilities; (D) The various vegetative covers; (II) The known runoff as determined by reliable stream gauging stations using interpolations when necessary from comparable gauging stations and relating interpolations to the characteristics of the basin measured by the comparable gauging stations as related to the basin of runoff being determined; (III) The slope or slopes of the terrain whose surface runoff contributes to the surface water flows at the place at which a determination of probable future surface water flows is required. (b) The state engineer shall promulgate rules pursuant to section 24-4-103, C.R.S., which include other factors for consideration in any area or situation in which calculations based on the criteria in paragraph (a) of this subsection (3) will probably be made more accurate by use of other or additional criteria. Whenever conditions are such that records of past precipitation are an appropriate factor, he may designate any portion of official precipitation records of agencies of the United States or of the state of Colorado which are appropriate in evaluating probable future water flows. He may approve use of factors referred to in this paragraph (b) with respect to particular areas or design of specific structures when requested to do so. (c) No dam safety requirement shall be imposed to meet a potential hazard of a flood whose magnitude is such that the hazard would probably exist whether or not the dam failed. (3.5) Whenever a determination of probable future surface water flows, or the probability of frequency of their recurrence, at any place in Colorado is required by relation to a longer period of flow than that for which there is a reliable record of flow as defined in subsection (3) of this section, the determination shall be made by interpolation and correlation of known records to the longer period by relating known records of water basins as similar as reasonably possible to the place of determination or basin under consideration, or by use of geologic determinations, or by use of other methods reasonably calculated to formulate an accurate estimate of probable future flows or the probability of frequency of their recurrence at the place of determination of such flows. (3.7) Calculations of probable flows or frequency of recurrence based upon application of the principles set forth in subsections (3) and (3.5) of this section shall relieve anyone acting in accordance with such principles of any liability respecting an occurrence different than that predicted. This exemption from liability shall apply to the state and its public officials or employees when acting in performance of their public duties. (4) The owners of any reservoir may conduct the waters legally stored therein into and along any of the natural streams of the state, but not so as to raise the waters thereof above ordinary high watermark, and may take the same out again at any point desired if no material injury results to the prior or subsequent rights of others to other waters in said natural streams. Due allowance shall be made for evaporation and other losses from natural causes for the protection of all rights to the waters flowing in said streams, such losses to be determined by the state engineer.

C.R.S. § 37-87-103 Notice of release of stored water

37-87-103. Notice of release of stored water. The owner of a reservoir who uses the reservoir for water storage shall give reasonable notice to the division engineer of the division in which the reservoir is located of the date on which the reservoir owner desires to release stored water into any natural streams, together with the amount to be released in cubic feet per second, the duration of the releases, and the name of the structure or other location to which the water released from storage is to be delivered, to allow the water officials in charge of any stream into which the stored water is released to make and record the necessary measurements of flow and storage and to provide for a proper patrol of the stream, for the protection of the reservoir owner and all other appropriators along the stream whose interests might be affected as a result of the reservoir release.

C.R.S. § 37-87-104 Liability of owners for damage

37-87-104. Liability of owners for damage. (1) Any provision of law to the contrary notwithstanding, no entity or person who owns, controls, or operates a water storage reservoir shall be held liable for any personal injury or property damage resulting from water escaping from that reservoir by overflow or as a result of the failure or partial failure of the structure or structures forming that reservoir unless such failure or partial failure has been proximately caused by the negligence of that entity or person. No entity or person shall be required to pay punitive or exemplary damages for such negligence in excess of that provided by law. Any previous rule of law imposing absolute or strict liability on such an entity or person is hereby repealed. (2) No such entity or person shall be liable for allowing the inflow to such reservoir to pass through it into the natural stream below such reservoir. (3) (a) No stockholder, officer, or member of a board of directors of an owner of a reservoir shall be liable for any personal injury or property damage resulting from water escaping from such reservoir or as a result of the failure or partial failure of the structure or structures forming such reservoir for which the owner shall have been found liable if a valid liability insurance policy, or adequate substitute as provided in paragraph (b) of this subsection (3), has been purchased by the owner of the reservoir and is in effect at the time such damage occurs. Such insurance policy shall insure against such damages and provide coverage in an amount of not less than fifty thousand dollars for each claim and in an aggregate amount of not less than five hundred thousand dollars for all claims which arise out of any one incident. The policy may provide that it does not apply to any act or omission of a stockholder, officer, or member of a board of directors of an owner if such act or omission is dishonest, fraudulent, malicious, or criminal. The policy may also contain other reasonable provisions with respect to policy periods, territory, claims, conditions, and other matters common to such policies of insurance. The limitation of liability pursuant to this paragraph (a) shall not apply to any criminal, fraudulent, or malicious act or omission by a member of the board of directors of the owner, an officer of the owner, or a stockholder of the owner, nor shall it apply to any ultra vires act of the owner or of a member of the board of directors, an officer, or a stockholder of such owner. The provisions of this paragraph (a) shall not be deemed to impose any liability upon a member of the board of directors, an officer, or a stockholder of the owner of a reservoir beyond that provided in section 7-42-118, C.R.S. (b) An adequate substitute for such insurance may be in the form of: (I) A good and sufficient bond, in an amount equal to such recovery limitations duly executed by a qualified corporate surety approved by the commissioner of insurance, conditioned upon the payment by the entity or person who owns, controls, or operates a water storage reservoir of any valid and final judgment for damages imposed within the judgment limitations established in this subsection (3); (I) A good and sufficient bond, in an amount equal to such recovery limitations duly executed by a qualified corporate surety approved by the commissioner of insurance, conditioned upon the payment by the entity or person who owns, controls, or operates a water storage reservoir of any valid and final judgment for damages imposed within the judgment limitations established in this subsection (3); (II) A good and sufficient escrow of acceptable securities, as defined in section 24-91-102, C.R.S., or an annual irrevocable letter or annual letters of credit issued by any national or state bank or any bank for cooperatives as chartered under Title III of the federal "Farm Credit Act of 1971", as amended, and deposited with an escrow agent pursuant to an escrow contract or agreement requiring the escrow agent to pay from the escrow account amounts necessary to discharge a valid and final judgment for damages within the limits established in this subsection (3). Such escrow contract or agreement shall provide that it cannot be revoked or amended until after any claims for damage against such entity or person have been discharged or until applicable statutes of limitations pertaining thereto have expired. (III) A combination of insurance and any of the substitutes described in this paragraph (b).

C.R.S. § 37-87-104.5 Notification of ownership of dam - when person in control deemed owner

37-87-104.5. Notification of ownership of dam - when person in control deemed owner. The person or persons actually in control of the physical structure of any dam shall be deemed, for determining liability arising from ownership of a dam and with respect to operation thereof, to be the owners thereof unless notice of the name and address of the true owner thereof, together with reasonable evidence of such ownership, has been filed in the office of the state engineer by January 1, 1985. Any change in ownership shall be immediately filed in the office of the state engineer.

C.R.S. § 37-87-105 Approval of plans for reservoir - notice of modification

37-87-105. Approval of plans for reservoir - notice of modification. (1) No dam shall be constructed in this state to impound water above the elevation of the natural surface of the ground for the purpose of creating a reservoir with a capacity of more than one hundred acre-feet of water or with a surface area at the high water line in excess of twenty acres or if the height of the dam will exceed ten feet measured vertically from the elevation of the lowest point of the natural surface of the ground, where that point occurs along the longitudinal centerline of the dam, up to the flowline crest of the spillway of the dam before plans and specifications for that dam have been filed in the office of the state engineer and approved by him in accordance with regulations established by the state engineer governing such structures. (2) Repealed. (3) In making his determination for approval, the state engineer shall be guided by dam, spillway, and construction regulations established pursuant to this article. Such regulations may include less stringent requirements than those dictated by consideration of probable maximum precipitation. The state engineer shall issue his written decision regarding the approval of plans and specifications within one hundred eighty days of submittal to him. The state engineer shall have authority to require the material used and the work of construction to be accomplished in accordance with regulations which the state engineer may establish. No work shall be deemed complete until the state engineer furnishes to the owners of such structures a written statement of acceptance, which statement shall specify the dimensions of such dam and capacity of such reservoir. The state engineer shall render his written decision regarding acceptance within sixty days of written notification by the owner that construction has been completed. (4) No alteration, modification, repair, or enlargement of a reservoir or dam which will affect the safety of the structure shall be made without prior written notice and approval in accordance with this section to the state engineer. General maintenance, ordinary repairs, or emergency actions not impairing safety shall be excluded from the terms of this subsection (4).

C.R.S. § 37-87-106 Cost of inspections and observation

37-87-106. Cost of inspections and observation. (Repealed)

C.R.S. § 37-87-107 Safety inspections - amount of water to be stored

37-87-107. Safety inspections - amount of water to be stored. Dam safety inspections shall be made on all dams within the state by qualified, experienced personnel as often as the state engineer deems necessary or appropriate for the protection of public health and safety so that a determination of the amount of water which is safe to impound in the reservoir can be made by the state engineer. The dam safety inspections shall include, but shall not be limited to, review of previous inspections, reports and drawings, site inspection of the dam, spillways, outlet facilities, seepage control and measurement system, and permanent monument or monitoring installations, if any. Based upon inspection reports and other information affecting the safety of each dam, the state engineer shall determine the amount of water which is safe to impound in the reservoir. It is unlawful for the owners of any reservoir to store in said reservoir water in excess of the amount so determined by the state engineer to be safe.

C.R.S. § 37-87-108 Withdrawal of excess water

37-87-108. Withdrawal of excess water. If the owners of any such reservoir impound water therein to a depth greater than that determined by the state engineer to be safe, it is the duty of the division engineer of the district wherein such reservoir is located to forthwith proceed to withdraw from said reservoir so much of the water as shall be in excess of the amount so determined by the state engineer to be safe, and the division engineer shall close the inlets to the same to prevent said reservoir from being refilled to an amount beyond what said state engineer has designated as being safe. If the owners of said reservoir, or any other persons, interfere with the division engineer in the discharge of said duty, the said division engineer shall call to his aid such persons as he deems necessary and employ such force as the circumstances demand to enable him to comply with the requirements of this section. Any costs incurred by the state engineer in rectifying a failure of compliance by the owner may be recovered in a suit for civil damages.

C.R.S. § 37-87-108.5 Emergency actions

37-87-108.5. Emergency actions. (1) If, in the opinion of the state engineer, conditions of any dam or reservoir are so dangerous to the health and safety of life or property as not to permit time for issuance and enforcement of an order relative to construction, modification, maintenance, or restriction of storage, or the dam is threatened by any large flood, the state engineer may immediately employ remedial measures necessary to protect such life and property. (2) (a) The state engineer shall maintain complete control of any such dam or reservoir which, pursuant to subsection (1) of this section, has been determined to be dangerous to life or property until such dam or reservoir is deemed safe, or until any emergency conditions which precipitated the state engineer taking control of any such dam or reservoir, pursuant to subsection (1) of this section, have abated. The state engineer is hereby empowered to determine the proper time at which to relinquish control of any such dam or reservoir. (b) For purposes of this paragraph (b), measures taken by the state engineer pursuant to subsection (1) of this section shall be deemed final action by the state engineer for purposes of judicial review. The owner or operator of any dam upon which the state engineer has employed remedial measures pursuant to subsection (1) of this section may seek judicial review of the propriety of such measures by filing an action in the state district court for the district in which such dam is located. (3) (a) Any necessary and reasonable costs and expenses incurred by the state engineer in fulfilling the duties mandated by subsections (1) and (2) of this section in connection with a remedial or emergency action shall be recoverable by the state engineer from the owner of any such dangerous or threatened dam. (b) Any owner failing or refusing, after written notice has been given, to pay the reasonable costs and expenses incurred by the state engineer pursuant to paragraph (a) of this subsection (3) shall be, upon complaint by the state engineer to the attorney general, subject to reasonable attorney fees incurred in the recovery of such costs and expenses. (4) (a) All moneys collected by the state engineer pursuant to subsection (3) of this section shall be credited to the emergency dam repair cash fund created in section 37-60-122.5, to the extent necessary to replenish the account. Moneys collected in excess of such amount shall be credited to the Colorado water conservation board construction fund. (b) The general assembly shall make annual appropriations from the emergency dam repair cash fund created in section 37-60-122.5, for the direct and indirect costs incurred by the state engineer in the performance of those duties authorized to be carried out by the state engineer in this section.

C.R.S. § 37-87-109 Complaint that reservoir is unsafe

37-87-109. Complaint that reservoir is unsafe. Upon complaint being made to the state engineer by one or more persons residing or having property in such a location that their homes or property would be in danger of destruction or damage in the event of a flood occurring on account of the breaking of the embankment of any reservoir within the state, that said reservoir is in an unsafe condition, or that it is being filled with water to such an extent as to render it unsafe, it is the duty of the state engineer to forthwith examine said reservoir and determine the amount of water it is safe to impound therein. If, upon such examination, the state engineer finds that said reservoir is unsafe, or is being filled with water to such an extent as to render it unsafe, it is his duty to immediately cause said water to be drawn from said reservoir to such an extent as will, in his judgment, render the same safe. If water is then flowing into said reservoir, he shall cause it to be discontinued.

C.R.S. § 37-87-110 Engineer may use force

37-87-110. Engineer may use force. The state engineer is authorized to use such force as is necessary to perform the duties required of him in section 37-87-109 and to have and exercise all of the powers conferred upon the division engineer by section 37-87-108. If, after any of such reservoirs have been examined by said state engineer, the owners thereof, or any other person, fills or attempts to fill them, or any of them, to a point in excess of the amount the state engineer has determined to be safe, then it is the duty of the division engineer of the district wherein such reservoir is located to proceed as directed by section 37-87-108. All direct, actual, and necessary expenses incurred in performing any action authorized by this section shall be recoverable by the state engineer from the owner of the affected reservoir and if not reimbursed may be collected by action brought by the state engineer in the district court of the county in which the reservoir, or part thereof, is located.

C.R.S. § 37-87-111 Expense of examination

37-87-111. Expense of examination. The person calling upon the state engineer to perform the duty required of him by section 37-87-109, if the request is frivolous or made in bad faith, shall pay him any invoiced expenses and mileage at the rate prevailing for state officers and employees under section 24-9-104, C.R.S., for each mile actually and necessarily traveled in going to and from said reservoir, and, should the state engineer find upon examination that such reservoir is in an unsafe condition, the owners thereof shall be liable for all expenses incurred in such examination.

C.R.S. § 37-87-112 Review of action of state engineer

37-87-112. Review of action of state engineer. Any action of the state engineer under section 37-87-110 shall be subject to review in a de novo proceeding commenced by complaint of the owner in the district court in and for the county where the affected structure is located. When the state engineer has directed that certain measures shall be taken immediately for the protection of the public safety, any such judicial proceeding shall be accelerated on the court's calendar and determined immediately upon the conclusion of such proceeding. The judgment and action of the state engineer shall control until judicial determination of the cause.

C.R.S. § 37-87-113 Breakage of reservoir - damages

37-87-113. Breakage of reservoir - damages. (Repealed)

C.R.S. § 37-87-114 Penalty - disposition of fines

37-87-114. Penalty - disposition of fines. (1) Any reservoir owner or operator failing or refusing, after notice in writing has been given, to obey the reasonable directions of the state engineer as to the construction or safe operation of any reservoir shall be subject to a fine of not less than five hundred dollars for each offense, and each day's continuance after time of notice has expired shall be considered a separate offense. Such fines shall be recovered by civil action in the name of the people by the district attorney, upon the complaint of the state engineer, in the district court of the county where the injury complained of occurred. The proceeds of all fines, after payment of costs and charges of the proceedings, shall be paid into the county treasury for the use of the general fund of the county. (2) Upon the complaint of the state engineer, the attorney general is authorized to commence proceedings against any reservoir owner or operator for refusing, after notice in writing has been given, to obey the directions of the state engineer as to the construction or safe operation of any reservoir to secure compliance with any such reasonable direction necessary for public safety in the district court of the county wherein any portion of such reservoir is located, pursuant to the Colorado rules of civil procedure; except that, if it appears to the court that the public safety is in jeopardy as the result of a failure to obey the directions of the state engineer, the court shall expedite the proceedings so that determinations may be made with respect to the directions of the state engineer commencing not later than twenty days from the service of the complaint on the owner or operator of a reservoir.

C.R.S. § 37-87-114.4 Annual report

37-87-114.4. Annual report. Notwithstanding section 24-1-136 (11)(a)(I), the state engineer shall submit an annual report to the general assembly by November 1 of each year concerning the activities of the state engineer and the division of water resources relating to sections 37-87-105 to 37-87-114 for the preceding fiscal year. The report must include information on the following: Approvals of plans and specifications for construction of dams and reservoirs and for alterations, modifications, repairs, and enlargements; number of safety inspections made and the results thereof; use of appropriated funds; receipts generated for inspections of dams and reservoirs; rules and regulations adopted or amended; enforcement orders and proceedings; dam failures and reasons therefor; and other available data regarding the effectiveness of the state's dam and reservoir safety program.

37-87-121. Application to existing dams. (Repealed)

C.R.S. § 37-87-122 Erosion control dams

37-87-122. Erosion control dams. (1) The provisions of sections 37-87-101 to 37-87-108 shall not apply to erosion control dams of the character defined in this section, unless such dams also come within the specification requirements of said sections. (2) Erosion control dams for reservoirs may be constructed on watercourses, the channels of which have been determined by the state engineer to be normally dry, having a vertical height not exceeding fifteen feet from the bottom of the channel to the bottom of the spillway, and having a capacity not exceeding ten acre-feet at the emergency spillway level, upon approval of an application for such erosion control dam by the state engineer, which application shall be accompanied by a fee of fifteen dollars. The approval by the state engineer of an erosion control dam shall be chronologically numbered in order of approval and in concert with any livestock water tanks approved pursuant to section 35-49-109, C.R.S. When such reservoirs are to be constructed with such height exceeding fifteen feet and such capacity exceeding ten acre-feet, they shall be constructed in accordance with section 37-87-105. (3) Such reservoirs may be constructed with a capacity in excess of two acre-feet if, at or below the two acre-feet level, an ungated outlet tube is installed, with twelve inches minimum diameter and large enough to assure adequate capacity to drain within thirty-six hours any impoundment in excess of two acre-feet. (4) The state engineer shall prepare and keep on file at the office of the state engineer standard specifications for erosion control dams which shall be subject to revision by the state engineer and shall in general be used as a guide by persons proposing to construct such dams. (5) The fees collected pursuant to subsection (2) of this section shall be deposited by the state engineer with the state treasurer, who shall credit all such fees to the general fund of the state.

C.R.S. § 37-87-123 Dam and reservoir information

37-87-123. Dam and reservoir information. (Repealed)

C.R.S. § 37-87-124 Restriction of facilities within reservoirs

37-87-124. Restriction of facilities within reservoirs. (1) The general assembly hereby declares that the prevention of seasonal flooding which causes destruction of property and crops, loss of livestock, and risk or loss of human life is manifestly of greater concern and benefit to this state than the availability of recreational facilities and other facilities, not functionally related to the operation of the reservoir, constructed below the high water level of a reservoir. (2) In order to achieve the purposes of subsection (1) of this section, no person, including any state or federal agency, quasi-municipal corporation, or political subdivision, shall construct any permanent recreational structure within a reservoir below the elevation at the crest of the spillway of the reservoir unless such facility is constructed in such a manner as to withstand partial or complete inundation and sustain minimal or no damage thereby or unless such facility is necessary to the operation of the reservoir. Said facility should be capable of being restored to full recreational use with a minimum amount of cleaning or expense. This subsection (2) and subsection (3) of this section shall not apply to facilities completed before July 1, 1984, but shall apply to any enlargement or remodeling of such facilities. (3) The state engineer shall order the removal of any facilities constructed, enlarged, or remodeled in violation of this section. Such order may be appealed by the affected person or enforced by the state engineer pursuant to article 4 of title 24, C.R.S.

C.R.S. § 37-87-125 Notice of intent to construct impoundment structure

37-87-125. Notice of intent to construct impoundment structure. Any person proposing to construct a reservoir for the purpose of storing water, other than a reservoir specified in section 37-87-105 (1) or a livestock water tank as described in section 35-49-103, C.R.S., shall submit notice thereof to the state engineer prior to the beginning of any construction. Such notice shall include the location of such proposed reservoir with reference to section, township, and range and the dimensions of the reservoir, the dam, and the spillway. If any reservoir is constructed without the notice required by this section, the state engineer may prohibit the storage of water in such reservoir or direct the withdrawal of water from such reservoir.
