Yuba County Seeks Hydro Tweaks Impacting California Waters
Published Date: 7/8/2025
Notice
Summary
The Yuba County Water Agency wants to make some changes to their Yuba River Hydroelectric Project that don’t affect how much power it produces. This update affects local rivers and lands in California and needs approval from environmental and water quality agencies. People have until August 1, 2025, to share their thoughts or get involved—no big money changes, just important environmental checks!
Analyzed Economic Effects
1 provisions identified: 1 benefits, 0 costs, 0 mixed.
New Spillway Reduces Flood Levels
If you live near Marysville, California, the project would add an Atmospheric River Control (ARC) Spillway that raises release capacity to about 33,500 cubic feet per second (up from 19,000 cfs). That change would let operators release flood flows earlier, could lower water levels on flood levees near Marysville by up to 2.5 feet in a 1997-type storm event, and provides additional redundancy for releasing water if the existing spillway becomes inoperable.
