Watershed slow to saturate Flood Control Releases Limited
Few in Sept, Oct, Early Nov Vast Majority Releases <300 cfs
Downstream Estuary Higher but healthy salinities
Upstream Segments Supplemental Flows Worked!
Freshwater habitats avoided significant harm Saline waters migrated upstream following test (May-June)
