  Depth is not on record here, so the bank has to tell you. Look for where the old bank line still shows under the surface. Points where the flooded channel swings in are the reliable ones. Sevier County records list yellow perch, sockeye salmon, Utah sucker, brook trout and brown trout among the fish reported. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. The shape of Willies Flat Reservoir decides where the fish sit.
