To coin a phase  - "When hell the Smith freezes over"  -  As you know with only one turbine it takes twice as long to run the water that accumulates from  rain. It appears there is no such thing as "normal" rain anymore.  We will see what happens later on this spring and summer.

Nice article. I don't like how he is basically blaming the current 650cfs as the only problem and only mentioning the martinsville pond draw down once. We had acceptable temperatures down low when the dam was out (summer 2017) and ~350-~450cfs sluice was constant. If 350-450cfs constant was enough cool water, then 650cfs is plenty. Something else happened..just my .02

Mark and I talked about this, but it was just my speculation: The lake levels.
Big rain events have put a lot of water in the lake. Quickly. Warm water. This has happened for a few years. They draw the cold water off from deep. The warm water layer above sinks more quickly than normal and they start drawing off warmer water. With no mixing tower, there is no good way to avoid this.

Plausible hypothesis for sure. Ken made a good point a while back that there are many other warm water small streams other than towne creek. With big rain events, that same warm water that filled the lake is also pouring into the river, sometimes at an alarming rate. Also, with as much rain as we had, the warming effect could be exponentially higher than one expects.
