A project to move water from the Sacramento region down to Southern California was recently approved by the California Department of Water Resources (DWR). The $16 billion Delta Conveyance Project is causing major controversy around environmental concerns. This is a very complex issue, Californians are in need of water all over the state. But with a project like the delta tunnel, environmentalists say the 50 species of fish in the delta are at risk as well as the wildlife and people who depend on the fish.
