Document Description
NOTE: Review Per Lead The proposed project is to remove 836,000 cy of post-fire debris from Morris Reservoir. The project will remove sediment deposited during the 2009-2010 winter storms. The sediment removal would be accomplished by dewatering the reservoir and then mechanically agitating the sediment into a low flow, sluicing channel. The sediment will then be flushed from the Morris Dam through the San Gabriel River to Santa Fe Dam. The proposed cleanout will remove one Design Debris Event, which will keep the reservoir in compliance with capacity standards required for both flood protection and water conservation needs of the communities below.
