The closest I have been to belle river is fishing around Stevensville in the Grassylake area . Also the canal behind Doirons landing has some really deep water that I fish when it is cold out. I tie up to this guys fence in his back yard where he dropped some structure and fish about 12 feet deep on the edges of the brush and do really good but I know for a tournament you are looking for Quality not Quantity and I never picked up any thing worth bragging about there. Wish I could be more help.
