STOCKTON (AP) — California water officials are proposing changes to a multibillion-dollar plan for two water diversion tunnels for the Sacramento-San Joaquin Delta, according to documents released Thursday. The planned changes come in response to criticism voiced by local elected officials, farmers and landowners in the delta and are meant to reduce the tunnels' impacts on them, officials said. "Clearly the people in the delta would be impacted by the project, but we'll take every legally available step to mitigate the impacts," said California Natural Resources Secretary John Laird.
