I may have been wrong about inflow to the Lake - checking the Corps' page for lake stage and outflow I didn't notice the lake level go up much above what it had been before last week's storms and they don't seem to be releasing much water - maybe none - only 8 CFS cubic feet per second which is "nothing".
Date June 5 2004
Lake Elevation 866.00
Outflow 8 cfs
Air Temperature
Current 64 F
High 80 F
Low 61 F
