Enjoy a glass of cool, clear water today and think about how essential it is to life. Then go blow up a goddamn dam. (Not a sincere call to violence.)

While we consider the fate of the Colorado and the Rio Grande, note the effort to dam the last wild river in New Mexico, the Gila. Don’t let that happen.

Ten major dams—from the Hoover Dam, completed in 1936, to the Glen Canyon Dam, erected in 1966—impede the waterway’s natural flow. Adding to its woes are the numerous towns and industries that siphon water from it and its many tributaries as they meander to the sea.

This predicament and a few possible solutions drive the Redford Center–produced documentary Watershed, which is set to premiere on World Water Day—March 22—on Pivot. Additionally, Raise the River and Change the Course, the social action campaign for the 2012 world water crisis documentary Last Call at the Oasis, are working together to return water to the Colorado. Donations to Raise the River will help acquire permanent water rights to the river and help rebuild 2,300 acres of surrounding habitats.
