Thread: How deep is to deep for sinking structure ?

This lake is an old Miss. river horseshoe lake. About 10 miles long & 1/2 mile wide. The channel is around the outside of the horseshoe, close to the outside bank & 50' deep. So there is over a 1/4 strech strech sloping from the channel to the inside bank. We catch alot of fish on the shallow side under piers in 8-12' water. I have some bruch in 20' on the shallow side and it seems to do better than my 20' brush on the deep side. So would putting brush in 30' water on the shallow side be too deep? This would be in the middel of the lake & no structer at all out there! If you have any suggestions from the map attached please make them! Green is channell 50'deep, red spot is 30' deep & blue spots are 20' deep.
