Hi James, It's a rather poor image, but you may be able to see that 30' readout on my depth sounder. On Cheatham Lake, we have 30-feet from bank to bank most of the time, sometimes more, and even in that narrow channel at Gower Island it didn't get any less than 23 to 25. The only place on Cheatham we have to look out for is down below Harpeth Island, where there is a sand bar about a hundred yards long on the downhill side of the island, where they play volleyball in the summer and beach boats in the sand. Years ago we anchored TRADITION there in about five feet of water, did some swimming, walked around on the sand, had some fun. We are planning to tow a canoe down there next season and run up the Harpeth River a ways to spend the night, using the canoe for exploration and fishing on the Harpeth.
Up on Old Hickory it's a different story, as it's an impoundment rather than a "run of the river lake" like Cheatham is. Cheatham Lake is basically a much deeper river channel, and the terrain didn't allow it to flood much else. On Old Hickory, the impoundment flooded lots of farmland, and you really have to pay attention to the navigational markers,
red on right returning really means something when you are negotiating somewhere like Gallatin Marina channel, and that is where COFFEE BREAK ran aground and did major damage to her 1949 wood hull.

Paul
