PG&E is required to maintain a minimum of 500 cfs below the Pit 1 powerhouse at all times, though a short term deviation of -10% is allowed. Actual flows will usually be slightly higher to stay above the minimum. Typical combined outflow from the powerhouse and upstream river is around 2,000 cfs.
USGS has a pdf showing all the dams, diversions, powerhouses and gauges in the Pit and McCloud River Basins.
