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

HB 1691 extends the deadline for securing permits and funding for water supply projects under Washington's Yakima River Basin Integrated Plan from 2025 to 2035. This change affects the Department of Ecology and the Yakima River Basin water management program, which aims to provide 214,000 acre-feet of water annually for environmental, agricultural, and municipal uses. The bill amends specific state codes to update the milestone date and related funding review expiration, without altering the plan's core requirements. It provides additional time to complete projects while maintaining existing water rights and conservation goals.
