Blue Mountain Lake

There are two private boat launches along Route 28 in the village of Blue Mountain Lake which may charge a fee. Neither launch is suitable for boats over 20 feet long. There is state land on the north side of the lake, however most of the shoreline is privately owned.


Fish found within this lake include: lake trout, brook trout, smallmouth bass, brown bullhead, landlocked salmon, rainbow smelt, pumpkinseed, and yellow perch. Lake whitefish and redbreast sunfish were formerly common in this lake, but are now seldom caught. When fishing for cold water species, try to find the deep pockets where the coldest water is found. In a survey competed in 2004, there were several lake trout caught over 21 inches. Trolling for lake trout can be a challenge in this lake because of rapid changes in bottom depth. Many anglers prefer still fishing with suckers to catch the lakers. Salmon fishermen do well trolling flies along the surface near the inlet streams during the late April smelt spawning run. The southwest corner of the lake has shallow, rocky habitat which is preferred by smallmouth bass.


Every year this lake is stocked with approximately 510 Lake Trout and 1,300 Landlocked Salmon. Blue Mtn. Lake is one of the few lakes in Hamilton County that landlocked salmon are stocked in. Surplus brook trout fingerlings are stocked when available in the fall.
