2007 Drawdown

Note the differences between the blue line which represents lake level and the red line, which represents the stop block level. The difference between the two often exceeds twenty inches, meaning that 20 or more inches of water flows over the top of the stop blocks to maintain a given water level. Of course, water flow depends on precipitation, snow melt, and outflow from Keech Pond. You may view the complete data set, or download an excel spreadsheet.
