When California voters overwhelmingly approved Proposition 1, they specifically called for new storage to help the environment. The Sites project, a proposed off-stream reservoir north of the Delta meets this need, providing as much as 200,000 acre-feet a year of new flows for fish. Sites is a smart and long overdue investment that the California Water Commission must seize by giving its final approval on Wednesday to as much as $1 billion in Prop. 1 money.
