Re "Delta tunnels won't hurt Sacramento" (Another view, Jan. 4): Jerry Meral, formerly in charge of the Bay Delta Conservation Plan, contends that building massive tunnels under the Delta to divert water southward won't impact water supplying the Sacramento region. He states that layers of institutional guarantees ensure that Sacramentos water can never be diverted in that manner. Those institutional guarantees have been in place since the State Water Project began exporting Delta water in 1967, but they have not stopped the decline of the Delta ecosystem and our fisheries. Since 1967, the flow and water quality standards protecting the Delta have been violated hundreds of times without a single enforcement action taken. Statutes protecting the water code, area of origin and watershed have been ignored. Exemplifying these effects, populations of Delta smelt are down 98.9 percent; striped bass, 99.6 percent; longfin smelt, 9.7 percent; and American shad, 89.1 percent.
