Gauge Description:

AW negotiated real-time flow information and works cooperatively with PG&E to provide it through a web interface (AW Feather gauge). Via a new agreement reached in 2007 releases are scheduled for both Saturdays and Sundays generally on the fourth weekend of the month, July through September, from 10:00am until 4:00pm. The release flow is based on the historic hydrograph: the June release level is 1,600cfs, July @ 1,200cfs, and 1,000cfs for August - October. Currently minimum instream flows are now 180 cfs and in practice 250 cfs are often available in the river which can provide opportunities for a low flow trip down Tobin.
