Water for the farmers of California.

Democrats are against it. For decades, Democrats in general and California Democrats in particular have fought dam and reservoirs.

Article: An Engineered Drought

We do know two things. First, [current California Governor Jerry] Brown and other Democratic leaders will never concede that their own opposition in the 1970s (when California had about half its present population) to the completion of state and federal water projects, along with their more recent allowance of massive water diversions for fish and river enhancement, left no margin for error in a state now home to 40 million people. 

Second, the mandated restrictions will bring home another truth as lawns die, pools empty, and boutique gardens shrivel in the coastal corridor from La Jolla to Berkeley: the very idea of a 20-million-person corridor along the narrow, scenic Pacific Ocean and adjoining foothills is just as unnatural as “big” agriculture’s Westside farming. 

Article: House passes another bill to bring more water to California farmers

The House on Thursday passed GOP-led legislation designed to bring more water to California's farm belt amid a severe and lengthy drought. 

Similar legislation has failed in the last two congressional sessions, and the White House and Democrats remain opposed. 

The 170-page bill also sets deadlines for the completion of feasibility studies to build or enlarge five dams in the state and ends efforts to build up salmon populations in the San Joaquin River.

Article: House Democrats float new California water bill

The Democrats’ proposal omits new water storage projects or changes that boost irrigation deliveries to San Joaquin Valley farms, which have anchored House Republican drought-fighting efforts. Instead, it includes an array of water recycling grants, watershed protection programs, groundwater cleanup assistance and desalination studies, among other efforts.

Article: California flexes muscles in water tussle with farmers

California water regulators flexed their muscles by ordering a group of farmers to stop pumping from a branch of the San Joaquin River amid an escalating battle over how much power the state has to protect waterways that are drying up in the drought.

As the rest of the article makes plain, the farmers have long-standing, legally-binding water rights that (Democrat run) California are trying to take away.
