USACE CWMS - San Joaquin Watershed

The Corps Water Management System (CWMS) includes four interrelated models to assist with water management for the basin:
- GeoHMS (Geospatial Hydrologic Modeling Extension)
- ResSIM (Reservoir System Simulation)
- RAS (River Analysis System)
- FIA (Flood Impact Analysis)

Other existing flood control improvements in addition to the major storage projects, have been constructed by the COE and local interests. These improvements include channelization, bypasses, storm drains, and levees along the banks of stream channels. There are also multiple headwater reservoirs controlled by different entitieis that can affect flood control in the major reservoirs.
