|Freshet flows AKA pulse flows are typical requirements of a hydropower license to maintain the river channel. These flows mimic the magnitude and timing of runoff associated with rain and snowmelt events that occur within a natural hydrograph. They maintain the river channel, transport sediment, build and maintain meadow systems through flooding and deposition of fine materials and they can trigger biological processes. But for our purposes they can also provide opportunities to boat!!!! Here are some opportunities on NF Feather and Pit 5 when PG&E releases required pulse flows!|
NORTH FORK FEATHER
Rock Creek Dam:
On 2/28 at approximately 1:00 am. Start of 1000 CFS pulse flow.
On 2/28 at approximately 1:00 pm. End of 12 hour 1000 CFS pulse flow.
On 2/28 at approximately 6:00 am. Start of 1000 CFS pulse flow.
On 2/28 at approximately 6:00 pm. End of 12 hour 1000 CFS pulse flow
March 5, 2021- begin ramping up to 1500 CFS
March 6- March 7- Maintain peak flow of 1500 CFS
March 8- March 12- begin ramping down, flows will decrease to ≈ 1348 CFS
March 12- March 17- next ramp down, flows will decrease to ≈ 1132
March 17- March 22- next ramp down, flows will decrease to ≈ 920 CFS
March 22- March 26- next ramp down, flows will decrease to ≈ 708 CFS.
One final note – the savvy opportunistic boaters may have noticed the gauge for PIT 4 which has been running at a flow of 2000+ cfs for the past month – PG&E reports the dual outage of their powerhouses should keep the flows boatable until 4/15/2021.
