Boating Study Releases Planned for Middle Yuba SF Yuba and Canyon Creek

 

American Whitewater is partnering with Nevada Irrigation District (NID) and Pacific Gas and Electric Company (PG&E) to identify a preferred range of whitewater boating flows on numerous reaches in the Yuba and Bear watersheds. Information obtained from surveys completed by boaters will help us identify flow preferences for whitewater boating. Flow preferences determined from boater surveys will be used to evaluate possible effects on whitewater boating from Project operation and help define flow needs.

 

Boater input is very important to this process. Please help us, yourself, and your friends by filling out a survey if you paddle any of the reaches noted below. Click here to fill out survey.

 

HIGHLIGHTS AS OF WEDNESDAY AFTERNOON, MAY 27

 

The flow study will continue on Thursday May 28 through Sunday May 31 on the Yuba Gap reach of the South Yuba--From Langs Crossing to above Washington.
