San Joaquin

Edison started releasing 1100 cfs on the morning of Oct 29, 2011. Both turbines at Mammoth Pool Powerhouse are offline for maintenance, so no water can go through the powerhouse. Edison needs to lower the reservoir and deliver water to their downstream powerhouses and to downstream water users. They have to send the water down the river bed. This release is expected to continue through the month of November and possibly into December. Changes in demand for the water could reduce or end the flows earlier.

View of Mammoth Pool and dam and the San Joaquin backcountry, from the 'Mile High Overlook'.
Mammoth Pool dam on the right with the spillway on the left side of the dome. A dirt road follows the spillway down then traverses to the base of the dam. This picture is taken from the Mile High Vista on Minarets Road. The river is less than a mile from the road at this point and the dam is less than two miles in a straight line. It is about a 2,500 foot drop in elevation cross country. There is no trail at present, but if a suitable route is found it would make an all year access route and reduce the shuttle by about an hour one way.
