The CALFED Bay-Delta program established the Suisun Marsh Levee Investigation Team (SMLIT) to gather information on the need to include Suisun Marsh Levees in the CALFED program, especially as they relate to CALFED Water Quality, Water Supply Reliability, and Environmental Restoration Program goals. The Suisun Marsh Planning Section supported the investigation with application of the DWRDSM1 Suisun Marsh Version model (DSM1) to evaluate hydrodynamics and salinity impacts of controlled and uncontrolled levee breaches in the Suisun Marsh.

Following are the DSM1 results included in the SMLIT Final Report document:
