This website provides information about the forecasted availability of water flows below various diversion dams associated with the Southern California Edison Company Big Creek Hydroelectric System in the Sierra National Forest. This data is considered preliminary and subject to change until it has been evaluated by the U.S. Geological Survey. Southern California Edison does not guarantee the accuracy of this data and notes that river flows may vary considerably during each day and from day to day. BE AWARE that river recreation can be hazardous due to high flows, currents, eddies, floating debris, submerged rocks, and other hazards. It is the responsibility of the recreationist to determine whether conditions are safe to enter flowing water.
