(Westernfarmpress) - Grape growers in Sonoma and Mendocino Counties have sued the California Water Resources Control Board over its new regulations on how farmers use water from the Russian River watershed. The group, called the Russian River Water Users for the Environment, is comprised of several dozen farmers who grow grapes for wine production in the Russian River watershed. They say the regulations are unconstitutional, too broad and sweeping and don't address steps that growers are already taking to protect salmon and steelhead populations.
