Based on flow at Camanche Dam, the 50 percent exceedance flow peaks at about 700 cubic feet per second (cfs) during the height of the irrigation season (June) and declines to between 200-300 cfs during the winter. The 10 percent exceedance flow (high flow) ranges between 1,000 cfs (September) and 2,700 cfs (May), with the flow about 2,000 cfs from January through May. The 90 percent exceedance flow (low flow) only ranges between about 100 and 300 cfs throughout the year; the highest flows occur from May through August because of water releases to the Woodbridge Irrigation District (WID).
