Chazy Lake

Chazy Lake lies in the town of Dannemora in northern Clinton County, 1,807 acres of cold Adirondack water tucked under the long ridge of Lyon Mountain. At 1,541 feet of elevation it sits high enough to hold late ice and cool summer temperatures, and the shoreline is mostly undeveloped forest, which gives the lake an emptier, more northern feel than its size and roadside access would suggest. Route 374 runs along the north side on its way from Dannemora to Chateaugay, and for most travelers the lake is a blue flash through the trees rather than a destination — which is exactly why it fishes as well as it does.

What makes Chazy unusual among Adirondack coldwater lakes is its shape. Maximum depth is only 72 feet and the mean depth is 33 feet, so the entire basin is shallow by lake trout standards. That geometry has real consequences for a fly angler. On a deep trench lake like Lake George or Lake Placid, lake trout drop out of fly range within weeks of ice-out; on Chazy the whole water column stays cold and mixed longer, and the fish that use it — lake trout, rainbows, and salmon — remain catchable on sinking lines well past the usual spring window.

The fishery rests on rainbow smelt. Smelt drive the growth of the lake trout, they concentrate predators against gravel shorelines and inlet mouths in spring, and they make a three-to-four-inch streamer the single most productive fly on the lake. Layered on top of that natural forage base is one of DEC's more generous stocking programs for the acreage: the most recent published actual stocking figures show 35,700 rainbow trout going into Chazy in a single year, alongside 1,500 lake trout. That is an enormous rainbow allotment for an 1,807-acre lake, and it means a fly angler working the shoreline shelves has a genuine numbers fishery, not just a trophy hunt.

Landlocked Atlantic salmon are also present and are listed among the lake's gamefish, though the most recent DEC actual-stocking report does not show salmon rows for Chazy — treat them as an occasional bonus rather than a target you plan a trip around, and check the current-year county stocking list if salmon are your reason for going. Smallmouth bass and northern pike round out the warmwater side, with smallmouth in particular offering good popper and streamer fishing along rocky shoreline through the summer months.

Access is straightforward: a DEC hard-surface launch off Route 374 about five miles west of Dannemora, with parking for roughly twenty vehicles with trailers and an accessible boarding dock. The north shore offers wadeable gravel where a shore angler can genuinely reach fish at ice-out. Chazy is a lake to fish in late April and May with a sinking line and a smelt pattern, to visit again in October when salmon and lakers color up near the inlet, and to enjoy on a Tuesday morning when the launch lot is empty and Lyon Mountain still has snow on it.

Chazy is a natural, moderately deep Adirondack lake with a broad, relatively even basin rather than a steep glacial trench. The DEC contour sheet shows the deepest water — roughly 70 feet — confined to a limited central area, with wide expanses of the lake falling in the 20-to-40-foot range and gradually shelving shorelines around most of the perimeter. The 33-foot mean depth is the single most important number on the map for a fly angler: it means the productive contours are reachable with a full-sink line over much of the lake, and it means the whole basin is thermally responsive.

Because the lake is comparatively shallow for a coldwater fishery, stratification sets up later and less severely than on the deep Adirondack lakes to the south. Spring turnover fish stay accessible into June, and even in midsummer the deeper central water holds enough cold, oxygenated volume to support lake trout. Water clarity is good — typical of a high-elevation forested watershed with limited shoreline development — which argues for longer leaders and fluorocarbon on flat, bright days.

Weed growth concentrates in the shallow bays and along the gentler north and south margins, where damselflies, dragonflies, and chironomids produce the summer insect activity. Rainbow smelt occupy open water and move shallow to spawn in spring, and they are the dominant forage. Wind has a long fetch across the open basin and builds a chop quickly; the leeward gravel shorelines are where smelt and predators end up.

Chazy's elevation and northern Clinton County location mean solid winter ice in most years, and the lake's mix of lake trout, rainbows, pike, and perch makes it an appealing hardwater destination. New York regulates ice fishing waterbody by waterbody and Chazy falls under DEC Region 5 special regulations, so confirm that the lake is open to ice fishing for the current season and check the applicable species limits before drilling a hole. The relatively shallow basin means the productive 20-to-40-foot contours are easy to find and work from the ice.
