Delta Conveyance Project and regional water supply
Long Beach
Summary
Metropolitan Water District's Dr. Maureen Martin briefed the commission on the Delta Conveyance tunnel — a 45-mile project to protect State Water Project deliveries from levee failure, sea level rise, and drought. Climate change is projected to cut those supplies by about 22%, and a final go/no-go decision is expected in 2027.
