Patoka is not like Rough and Barren as far as being able to pull water when it is high. They are pulling it about as fast as they can at about 2-3 inches per day. The Patoka river runs through mostly low farm land downstream of the lake, so if they pull too much water, there will be flooding. Every time it rains this winter, they have to stop pulling water from the lake to allow for the rain runoff into the river valley.
