Approved by Congress in 1944, construction on the dam started in 1966 and was completely finished in 1979 with a water elevation cap set at 844′ above sea level because of activists.
Heavy snow pack in 1982 resulted in the dam blowing well past that level and filling in 1983, to where it was flowing out the emergency spillway.
As near as I can tell from the historical data I’ve downloaded from the Calif. Dept of Water Resources the peak level of the reservoir was in July of 1985 at 1,218.88 feet above sea level.
1,077.53′ ASL in January of 1970, 1,082.8′ ASL in June of 1982 and July 2011 found it at 1,081.52′ ASL
In other words, despite the “Unprecedented Drought” that we are currently having, New Melones Reservoir is at this time 150′ and change higher then it was back in 1992

Those of us living here in California need to accept that simple fact that we live in a arid area that suffers occasional wet spells.
