We were hanging out in about 4 foot of water this past weekend... kept hoping I didn't end up stepping on a decomposed hand or something. We lose about 3 people a week on Lake Lewisville.
4 feet is way too shallow... too much killer crap in the mud, flesh eating bacteria, brain eating omebas, nope not fo rme, we'll hang out in 12 feet minimum, but the deeper the water the better. Usually around 20+ where we hang out.
