Trout season opens today and there may actually be a couple of stocked fishable rivers to try; one is the Chateaugay, the site of that disastrous sediment spill last year.According to the Department of Environmental Conservation, some of that sediment has now washed into Canada, though legal proceedings continue against the party responsible.As a result, the northern section from Sam Cook Road to the Canadian border will get fewer brook trout, at least until the sedimentation problem is completely fixed, but it will still be stocked in early April with some brookies in the 6-8 inch range.Elsewhere, the usual sections of rivers throughout the North Country will receive the mature 13-15 inch brown trout, and these include the Saranac, Boquet, LaChute, Ausable, St. Regis, Salmon (Malone area) and parts of the Chateaugay.

Boy Scout Clear Pond near Meachum Lake used to hold these small salmon, and West Pine Pond in the St. Regis Canoe Area, Preall says, still has some kokanee salmon, the result of natural reproduction.The endangered round whitefish, Preall adds, are also doing well in Little Green Pond near the St. Regis Canoe Area, where they are now 13-15 inches or twice the size of Cascade Lake round whitefish. The only problem, Preall says, was getting the eggs. "They didn't begin producing them until Dec. 4 last year, the day before the pond froze, so it was tough getting the few eggs we got. Next year should be better." The round whitefish in Little Green are only two years old.
