If they are releasing around 4,000 cfs its unfishable unless you floated it, with 1 unit going it will flow at around 1800-2000 cfs still be fishable in a few places, but I have never had much luck fishing it then. When they are just releasing a small amount and the flow is at 100-200 cfs the fishing is the best imo. If you look at lake tenkillers water levels, 632ft is where they like to keep it at. If its above that, like it is right now they are more likely to release water, they are also alot more likely to release even when its not scheduled. the opposite is true when the levels are below 632ft. You can also look at the inflow cfs and see how much water is coming into the lake, i think right now its around 3000cfs which is alot. It is usually around 500ish. With the rain that we just got overnight I would imagine it the inflow is going to go up quite a bit higher. So probobly no fishing for a couple of weeks or more until they get the lake level down to 632. Anyway just a couple things that I have noticed over the last few years.
