ROFLOL! You must not have looked at Keystone lake....

https://en.wikipedia.org/wiki/Keystone_Lake

It is v shaped southern leg is the Cimmaron River, and the Northern leg is the Salt fork of the Arkansas River. If you straightened them out, the combined length will be over 80 miles long!

I don't think the fish will run out, I have pulled 35 pounder fish out of this lake myself. Fish over 125 pounds have been caught recently from there. That is a lot of fish to eat, or to smoke, then eat, :)

There are a lot of feeder streams which is where I would put the net....
