With the exception of Lake \alley, the wholeof this water comes from the water-shed feeding theSouth Yuba river, and with the exception of BearValley Lake and Lake Valley, the storage water iscontrolled by Lake Spaulding, where it is drawn fromthe outlet gate into the river to be again divertedto the main canal leading to the lower country.
