Federal, state leaders pitch for California water tunnels

Representatives of California Gov. Jerry Brown and the Obama administration began making their pitch for approval Tuesday to build a pair of massive water tunnels under the Sacramento-San Joaquin River Delta.

They propose building the tunnels — each four stories high and running 35 miles long — to send Sacramento River water south to millions of residents and vast farmland in dry regions of the state. The project is estimated to cost of $15.7 billion.

Backers face opposition, however, from delta-area communities and farmers, who fear it will further degrade the hub of California's water system without producing more water for the drought-parched state.
