A Trump administration plan to pump more water to Central Valley farmlands is facing vehement opposition from Democratic members of Congress who represent the Sacramento–San Joaquin River Delta and the Bay Area. A group of seven legislators led by Rep. John Garamendi (D-Walnut Grove) said pumping more water will threaten the availability of water for many Californians, disrupt longstanding state-federal cooperation and put the Delta’s native fish at risk. … Federal officials have said the changes, adopted this month following an order by President Trump earlier this year, represent an effort to balance the needs of communities, farms and ecosystems.
