I fish some sand pits/strip mines that connect during high water periods and isolate during low water. There might be a hot bite on one while nothing on the other - sometimes during the same time/same day you might be able to view 100's of fish on one while you see 0 fish on the other. How have you sampled the downstream waters? Fishing? Underwater camera? Trapping? Word of mouth? Often in deep, clear water pits the fish will avoid being seen at all costs, because they are programmed to avoid birds who easily pick them off from above. Trow a large stick over a school of sun basking shallow bluegill in a sand pit during a warm afternoon and watch the water boil. You'll see 100 bluegill vanish. They are truly unique bodies of water and provide some challenging fishing at times!
