The first day of a months-long hearing that could determine the fate of the controversial twin tunnels provided no answers on Tuesday — nor was it expected to.But dozens of comments made by citizens, activist groups and water agencies showed just how divided the state is on the proposed $15 billion Delta “fix.”Tuesday’s testimony before the State Water Resources Control Board also revealed how diverse the Stockton-area opposition to the project has become. The tunnels are no longer a battleground solely for farmers and environmentalists of the old peripheral canal days.
