I put my boat down river, where the sipsey meets the mulberry, and almost made it up to the pumping station. We thought we might find some good fish in a deep hole down river. I would not recommend that. Nothing bad happened, just didnt catch any fish. Water temp didnt vary more than a couple degrees from the bridge down to the mulberry. Only place where it changed any was where a couple of creeks ran in, it would drop a couple degrees.
