A U.S. Geological Survey shows that a little more than half of the Colorado River, the West’s primary water source, is groundwater before it seeps into the river bed. The preliminary finding may help city water supply managers anticipate future volumes amid rising temperatures and less snowfall.

California’s State Senate has approved a bill that would ban drilling new wells where aquifers are in “critical overdraft,” and mandate that some cities and counties require permits for any applications to drill a well.
Oregon water systems will become more transparent about lead in drinking water, including the location of lead service lines and the results of mandatory tests.
In what could bode well for other small water systems in California, the city of Tulare will merge its water system with Pratt Mutual Water Co., which serves the neighboring disadvantaged community of Matheny Tract’s 1,200 residents.
