August 2019 Lake Levels and Flow Rates

A very high quantity of water continued flowing through Bagnell Dam in August, but flow rates seem to be dropping into a more normal range albeit on the high side. Lake levels themselves are well within norm and we should see things dropping slowly to about 658 by September's end.

Looking at the dam itself we can still see 3 of the "rake gates" open partially, indicating some flow over the spillways, but overall flow seems point too reduced power generation. It's an odd configuration with flood gates partially open, and power generation low, but I suspect the goal is to get surface currents moving to get some of debris out of the water. The lake has had a lot of organic debris in it all summer.  Here's the candlestick graph.

And the hourly detail graph for those interested...

and the monthly summary candlestick.  So much water!
