In 1909, the river left its old channel at a point about 29 miles below Yuma and turned west through Bee River into Volcano Lake. This necessitated the extending of the Sais Levee to an intersection with the Volcano Lake Levee and of raising and reinforcing the Volcano Lake Levee. Almost the entire silt [FIG. 3. MAP OF COLORADO RIVER DELTA REGION] load of the river was deposited in Volcano Lake and its bed was raised at a rate that made it difficult to keep the Volcano Lake Levee above it. In 1911, the Federal Government provided $1,000,000 to relieve the situation. The funds were used to build the Ockerson Levee in an attempt to put the river back into its old channel. (See Fig. 3.) The attempt was unsuccessful. In 1922, the Pescadero Cut-off was built and the river successfully turned from Bee Eiver and Volcano Lake into Pescadero Eiver. As a part of the Cut-off project, the Ockerson Levee was repaired and extended about 8 miles along the north bank of Bee Eiver, thence south across the river and down the west bank of the
