From what I remember seeing of the plant while flying it is located in a slow flow area of the Tennessee River. That is between two dams, Wilson Dam in Muscle Shoals and Guntersville Dam. At this time of year, middle of a hot August, with lower water levels you can see just how shallow the river is near Decatur, AL. During normal weather years this would not be a problem but this year is dryer and hotter than we usually have to endure.
Good point as well. Like I said, good thing we don’t have that problem. In fact, in winter we have to PREHEAT the water.
It might be an untested condition related to service water loads (safety train loads).
