SACRAMENTO, Calif. (AP) — An expert says small changes in agricultural irrigation practices could eliminate wasteful water use.

Delta Watermaster Craig Wilson says in a report being presented to the State Water Resources Control Board next week that California should crack down and aggressively enforce the state's ban on wasteful water use.

The Los Angeles Times reports Tuesday that Wilson proposes broader enforcement of the state Constitution's "reasonable use" doctrine rather than current case-by-case enforcement.

Wilson says serious water savings would be realized if agriculture used water more efficiently. He urges the state board to convene a summit, create an enforcement unit and streamline enforcement procedures.
