Welcome to the site! My first advice is to post this in your state forum so that you get some local advice. Secondly, make sure you understand that your lake may be stratified and a thermocline has set up. Fish at or above the thermocline. This may be very shallow, even tho the water temps are high. Little oxygen below thermocline keeps many fish in shallow water at this time of year, even at night. Someone who is better than I will help you, I'm sure!
