I believe you're correct about the Duck as well. Right around Normandy. Still about the same drive as it would be to the Caney.
I've looked at the charts before on the Resevoirs but I am not familiar enough with those places to understand them. Is 1 generator too much, what is low water elevation, how fast water moves from up near the dam to down river so forth and so on. May have to look into a guide of some sort to get the low down.
I hope this hasn't come across as looking for spots or anything of that nature. Just someone who has never had to worry about how many generators are running and high water/low water, etc. who is looking for information on how to understand that.
