I will mention a couple websites that might help you out. The information located here would be best used to indicate trends such as the river rising or falling. It can change drastically in the outflow overnight from Wolf Creek Dam in case of rain in the lake area. The first URL shows the discharge rate at Wolf Creek Dam, lake elevation above the dam and river elevation below. The second URL show the Cumberland River level at Celina Tennessee just over the state line. If you record these numbers over an extended period, it seems to indicate where the water level is going. Keeping in mind that there are no guarantees and that weather and demands for electricity can change the outflow without notice. You might still have trips where the water level have risen too high to fish. Good fishing.
