Following nine years of research, a California agency has proposed to increase water flows in the San Francisco Bay-Delta Estuary. But the decision is causing contention between farmers and fisheries. The California State Water Resources Control Board says the proposal will prevent an ecological crisis, including the total collapse of fisheries. About 70,000 fall-run Chinook salmon adults returned to the San Joaquin Basin in 1984, but that number fell to just 8,000 in 2014.
