AI Analysis
This bill extends the deadline for meeting key water supply goals in the Yakima River Basin from 2025 to 2035, while adding new requirements for independent review of large water projects and allowing land purchases for forest management — all tied to whether the state can secure permits and funding for major water supply infrastructure by 2035.
- Extends the water supply facility permit and funding milestone deadline from June 30, 2025, to June 30, 2035 — meaning the state now has until 2035 to secure permits and funding for at least 214,000 acre-feet of new water supply capacity.
- Requires the Washington State Water Research Center to independently review and evaluate the cost-benefit analysis of large water projects (over $100 million) before funding is approved, including assessing benefits for fish populations, drought resilience for irrigation, and municipal water reliability.
- Allows the Department of Natural Resources to purchase land (up to $100 million) for the Teanaway Community Forest using Common School Trust funds, with special loan terms (9% interest), bypassing normal land acquisition rules — but only if the land is managed under a transitional plan until the 2035 milestone is met or missed.
- Requires a transitional management plan for newly purchased land (e.g., Teanaway area) that prioritizes watershed protection, fish and wildlife habitat, and community input — and prohibits conversion to permanent management unless the water supply milestone is achieved by 2035.
- If the water supply milestone is not met by June 30, 2035, the land purchased under this authority must either be transferred to the Common School Trust or disposed of under permanent management rules — depending on the Board of Natural Resources’ decision.
Who is affected
- Yakama Nation — The Yakama Nation, as a key participant in developing the Yakima River Basin Integrated Plan, continues to have a role in shaping water and land management decisions in the basin.
- Farmers and irrigation districts — Irrigation districts and farmers who rely on water from the Yakima River may see changes in water availability and land-use rules affecting their operations, especially if new water supply facilities are built.
- Local governments — Local governments (counties and cities) in the Yakima basin, especially Kittitas County, will be involved in advisory roles and land management decisions, particularly around the Teanaway Community Forest.
- State agencies — State agencies — including the Department of Ecology, Department of Natural Resources, and Department of Fish and Wildlife — will take on new or expanded responsibilities for managing water resources, land acquisition, and forest management in the Yakima Basin.
- Public schools and the Common School Trust — The Common School Trust (which funds public schools) may be affected if state funds are loaned to purchase land, with interest payments flowing into school-related accounts.
Pro/Con Analysis
Stronger case for benefits
Potential Benefits (5)
Mandates independent, science-based evaluation of large water projects’ benefits for fish populations, drought resilience for irrigation, and municipal water reliability — strengthening ecological protection and ensuring public investments deliver measurable public benefits.
EnvironmentPeopleRef: Sec. 2(3) (requires evaluation of fish, drought resilience, and municipal water benefits)Requires inclusion of the Yakama Nation and diverse local stakeholders in land management decisions, reinforcing tribal sovereignty and community-based resource governance — a meaningful step toward equitable, inclusive decision-making in the Yakima Basin.
Rights & LibertiesPeopleRef: Sec. 3(2)(a)(v) (requires stakeholder advisory committee including Yakama Nation)Authorizes up to $100M for land acquisition to protect watershed health, fish habitat, and working forests — supporting long-term ecological resilience and public recreational access in a critically important basin.
EnvironmentLean peopleRef: Sec. 3(1) ($100M land purchase for Teanaway Community Forest)Extending the deadline to 2035 allows more time to secure permits and funding — reducing the risk of rushed, poorly vetted infrastructure projects — while adding independent review requirements that improve project quality and public accountability.
Public SafetyPeopleRef: Sec. 1(6) (extended deadline to 2035 with new review requirements)If the water supply milestone is met, the land remains in the community forest trust under permanent management — preserving watershed protection and habitat connectivity while allowing continued sustainable forestry and recreation.
EnvironmentPeopleRef: Sec. 3(3)(a) (conversion to permanent management if milestone met)
Potential Concerns (5)
Delaying the water supply milestone to 2035 increases the risk of water shortages during drought years, potentially threatening municipal water reliability and agricultural productivity in the Yakima Basin — especially for communities and farms already experiencing stress from climate-driven water scarcity.
Public SafetyRef: Sec. 1(6) (deadline extended to June 30, 2035)The bill authorizes a $100M loan from the Common School Trust (which funds public schools) at 9% interest — a high rate compared to typical state infrastructure financing — diverting school capital funds to a speculative land acquisition with uncertain returns, potentially weakening long-term school infrastructure funding.
FinancialRef: Sec. 3(1) ($100M loan from Common School Trust at 9% interest)If the 2035 milestone is not met, the land may be transferred to the Common School Trust — but this does not guarantee public benefit; instead, it opens the door to future development or sale of land that could have been preserved for watershed protection, potentially reducing public access and increasing housing/land pressure in Kittitas County.
HousingPeopleRef: Sec. 3(3)(b)(i) (land transfer to Common School Trust if milestone fails)Up to 12% of funding for independent reviews is allocated to administrative overhead — a relatively high rate that reduces the proportion of funds available for actual scientific analysis, potentially diluting the quality and scope of cost-benefit evaluations for large water projects.
FinancialRef: Sec. 2(6) (12% administrative overhead for Water Research Center reviews)The transitional management plan waives the usual requirement that community forest lands generate financial support for their management — potentially reducing local timber-related employment and revenue for rural counties like Kittitas, even as it protects watershed functions.

Who Is Most Affected
The Yakama Nation gains formal advisory authority in land and water management decisions, strengthening tribal co-stewardship and cultural resource protection — a positive shift toward self-determination in basin governance.
Farmers and irrigation districts may benefit from improved water reliability if new facilities are built by 2035, but face continued uncertainty and potential water shortages during the extended timeline — mixed impact with net negative short-term risk.
Local governments (especially Kittitas County) gain advisory roles and potential economic benefits from forest management, but may lose long-term revenue if land is not converted to permanent management — mixed impact with modest net benefit.
State agencies gain expanded authority and funding mechanisms, but face new accountability (independent reviews) and performance risk (milestone deadline) — mostly positive for agency capacity, but with added pressure to deliver results.
Public schools face a high-risk trade-off: 9% interest on $100M loans flows to school accounts, but the principal is not repaid unless the 2035 milestone is met — potentially weakening long-term capital funding if the project fails.
