On the lower end of the river where we put in in celina on the obey river I have seen several bass boats bigger than mine fishing for sauger several miles up the cumberland from the mouth of the obey into the cumberland river. avoid creek mouth shoals that can easily be seen and the min. depth is around 6 feet. avoid the v wakes on the surface which are again easily seen in the daytime which might be big logs on the bottom go slow and have fun. I have been there several times without a problem
