|I noticed that the South Fork at Chili Bar was ramped up to 2000 CFS on Wed. 7/31 and the next day too, from 4-6pm. Is this going to be a regular event? Anyone in the know?
|I discern no particular pattern for these surges. I expect most of them are based on demand for electricity from SMUD's customers, so hotter days are more likely to result in a surge. But I'm betting there's no absolute rule here.|
My (limited) understanding is that SMUD also releases part of the time on instructions from ISO (California's Independent System Operator), which balances water/electricity needs across the State. The result would be a surge like you've been seeing, often rocketing up to 2500 or 3000 cfs - and often ramping up just before dark . Since ISO balances needs impartially between operators, I know of no way to know when they'll call on SMUD.
