SB 5303 Washington Senate · 2025-2026 Regular Session

Extending the water supply milestone for the Yakima river basin integrated plan to 2035.

SB 5303 extends a key water supply milestone for the Yakima River Basin Integrated Plan from 2025 to 2035. This bill changes the deadline for securing permits and funding to begin construction on water supply facilities designed to provide at least 214,000 acre-feet of water. It also prolongs the State of Washington Water Research Center's role in reviewing cost-benefit analyses for large water supply projects within the plan until July 1, 2035. The legislation maintains the requirement that at least half of the plan's total costs must be funded by federal, private, and other non-state sources.
