in effect

RCW 90.90.005 Finding.

(1) The legislature finds that a key priority of water resource management in the Columbia river basin is the development of new water supplies that includes storage and conservation in order to meet the economic and community development needs of people and the instream flow needs of fish. (2) The legislature therefore declares that a Columbia river basin water supply development program is needed, and directs the department of ecology to aggressively pursue the development of water supplies to benefit both instream and out-of-stream uses.

RCW 90.90.060 Additional releases of water from Lake Roosevelt.

(1) In 2006, the legislature enacted chapter 6, Laws of 2006, an act relating to water resource management in the Columbia river basin. In its enactment, the legislature established that a key priority of water resource management in the Columbia river basin is the development of new water supplies to meet economic and community development needs concurrent with instream flow needs. (2) Consistent with this intent, the governor and the legislature are in agreement with the Confederated Tribes of the Colville Reservation and the Spokane Tribe of Indians to support additional releases of water from Lake Roosevelt. Because the sovereign and proprietary interests of these tribal governments are directly affected by water levels in Lake Roosevelt, the state intends to share a portion of the benefits derived from Lake Roosevelt water releases and to mitigate for any impacts such releases may have upon the tribes. (3) These new releases of Lake Roosevelt water of approximately eighty-two thousand five hundred acre feet of water, increasing to no more than one hundred thirty-two thousand five hundred acre feet of water in drought years, will bolster the state economy and will meet the following critical needs: New surface water supplies for farmers to replace the use of diminishing groundwater in the Odessa aquifer; new water supplies for municipalities with pending water right applications; enhanced certainty for agricultural water users with water rights that are interruptible during times of drought; and water to increase flows in the river when salmon need it most. (4) Nothing in chapter 82, Laws of 2008 expands, impairs, or otherwise affects the existing status and sovereignty of the tribal governments involved in Lake Roosevelt water releases pursuant to this section and RCW 90.90.070 .

RCW 90.90.100 Columbia river basin water supply revenue recovery account — Water service contracts.

(1) The Columbia river basin water supply revenue recovery account is created in the state treasury. All receipts from direct appropriations from the legislature, moneys directed to the account pursuant to RCW 90.90.020 and * 90.90.030 , revenue from water service contracts described in this chapter, or moneys directed into the account from any other sources must be deposited in the account. Moneys in the account may be spent only after appropriation. Expenditures from the account may be used only as provided in this section. (2)(a) Expenditures from the Columbia river basin water supply revenue recovery account may be used to assess, plan, and develop new storage, improve or alter operations of existing storage facilities, implement conservation projects, develop pump exchanges, or any other actions designed to provide access to new water supplies within the Columbia river basin for both instream and out-of-stream uses. Except for the development of new storage projects and pump exchanges, there may be no expenditures from the account for water acquisition or transfers from one water resource inventory area to another without specific legislative authority. For the purposes of this section, the term "pump exchanges" means water supply development projects that exchange water from one source to another or relocate an existing diversion downstream, with resulting instream benefit. (b) Two-thirds of the moneys placed in the account must be used to support the development of new storage facilities and pump exchanges; the remaining one-third of the moneys must be used for the other purposes listed in this section. (3)(a) Funds may not be expended from the account for the construction of a new storage facility until the department of ecology evaluates the following: (i) Water uses to be served by the facility; (ii) The quantity of water necessary to meet those uses; (iii) The benefits and costs to the state of meeting those uses, including short-term and long-term economic, cultural, and environmental effects; and (iv) Alternative means of supplying water to meet those uses, including the costs of those alternatives and an analysis of the extent to which long-term water supply needs can be met using these alternatives. (b) The department of ecology may rely on studies and information developed through compliance with other state and federal permit requirements and other sources. The department shall compile its findings and conclusions, and provide a summary of the information it reviewed.

(2) In developing water supply solutions in the Walla Walla river basin, the department of ecology should employ an integrated water resource management strategy that will provide concurrent water supply benefits to both instream and out-of-stream uses and address a variety of water resource and ecosystem challenges affecting fish passage, habitat functions, and agricultural, municipal, industrial, and domestic water supply, consistent with the Walla Walla water 2050 plan. (3) The department of ecology shall consider any increase in the quantity of water supply due to a project being implemented under the Walla Walla water 2050 plan that is completed after July 23, 2023, to be water supply developed under this section.

(10) Water supplies developed under this section must be managed consistent with the intent of the specific project being implemented. (11) It is the intent of the legislature for the state to share in the cost to implement the Walla Walla water 2050 plan authorized under this section, subject to the availability of amounts appropriated for this specific purpose, with at least one-half of the total costs to finance the implementation of the Walla Walla water 2050 plan funded through federal, private, and other nonstate sources, including private funding sources from entities that benefit from projects. This section applies to the total costs of the Walla Walla water 2050 plan and not to individual projects within the plan and includes funding for projects that have been completed prior to July 23, 2023. (12) Nothing in this section prevents the department of ecology from regulating water users consistent with existing adjudications to ensure that water use by holders of adjudicated surface water right certificates are not impaired by use under junior groundwater right certificates, claims, and permits.
