BAY DELTA SCIENCE CONFERENCE: Before and After: Evaluating the effect of the 1995 Delta spring standards on actual outflows into San Francisco Bay

Dr. Tina Swanson gives her analysis of the standard; has it really resulted in increased Delta outflow? Fresh water flowing into the Delta is highly contested and tightly managed.
