Suisun Marsh Salinity Control Gates Action Pilot Study

Description / purpose

In summer 2018 we used a unique water control structure in the San Francisco Estuary to direct a managed flow pulse into Suisun Marsh. Field monitoring showed that turbidity and chlorophyll were at higher levels in Suisun Marsh, representing better habitat conditions, than the upstream Sacramento River region throughout the study period. Fish monitoring data suggested that small numbers of Delta Smelt colonized Suisun Marsh from the Sacramento River during the 2018 Flow Action.
