Rising river levels? It’s been a surprising sight in recent days for people out along the American River. California is in year three of a severe drought and people are being asked to conserve, but water releases from Folsom Dam are being dramatically increased this week…. The Bureau of Reclamation, which manages Folsom Dam, said a small portion of the increased water is going to farms and cities downstream. But the majority of the higher flow is to help flush out salt water that is pushing up into the Sacramento-San Joaquin Delta.
