The state’s water users will find out soon if they will be paying for the $17 billion tunnel project called the California WaterFix. The controversial plan proposes building tunnels under the Sacramento Delta to secure the supply of water being sent south. But the plan is already finding itself in rough waters. The $17 billion project has the backing of California Gov. Jerry Brown and Southern California’s largest water wholesaler, the Metropolitan Water District. But farmers in the Westland’s Water District have decided the project is too expensive.
