Hey Gofish, The surface temp on the main lake at Canyon yesterday was 81ºF. Up river on Canyon the surface temp was 78ºF. On September 20th, on Saguaro, the water temp on the surface was 81 ºF and was 78.8ºF on the bottom in 33.1 feet of water by the no-wake buoys at the start of the river. A 2.2ºF temperature drop from the surface to 33.1 feet tells me that maybe the water is beginning to turn over. On Canyon, there were a lot of fish life showing up on the fish finder in the 50-60 ft. range.
