The lower American River, below Nimbus Dam has boatable flows all year round. Flows are highest in the spring ranging from 4,000 cfs in drier years to 10,000 cfs in average years and much higher in wet years. Flows are lowest in the winter, but do not drop below 1000 cfs in most years.
Water from Folsom Reservoir is released from the dam through a powehouse to generate electricity. Flows vary during the day according to power demand. Nimbus dam forms a much smaller reservoir just big enough to reregulate or smooth out the variable flows from Folsom. Water from Nimbus is also released through turbines to produce electricity. A large portion of the water in Nimbus reservoir is sent out through the Folsom South Canal for municipal and industrial use in Sacramento and San Joaquin Counties.
