thought I posted this question a few hours ago, but can't find it anywhere. May be my old himers kicking in... at any rate... here is the background... Kaw Lake generally runs from the North to the South, with the dam on the southern end. The dam has 6 gates, and when I was there today, all the gates were closed. The water in the tail race looked normal until you looked closer. Normally the water flows from the dam in a down stream direction. The water in the river was flowing towards the dam on the west side, and from the dam on the east side. Those of you familiar with the tail race knows there are rocks at the end of the pool where the water is released. The water was running over these rocks in both directions like white water, or rapids. I know it wasn't the wind, as the wind was from the north, and the tailrace is protected by the dam. What would make the water on one side of a river flow uphill (if you will) and down hill on the other side of the river? Anyone have a theory?
