Lake Champlain

Where it is

Lake Champlain stretches roughly 120 miles north-to-south between Vermont and New York, with a narrow southern arm and a wide, deep main basin to the north that opens into the broad lake near the Canadian border. At 271,000 acres and 400 feet at its deepest point, it fishes more like several different lakes joined end to end than a single reservoir.

Two fisheries, one lake

Champlain hosts both largemouth and smallmouth in numbers and quality, but they live in different parts of the system. The shallow, weedy southern third (Ticonderoga south, plus Missisquoi Bay in the far north) is largemouth water — milfoil flats, lily pads, drowned timber. The rocky main basin from Crown Point north through the islands is smallmouth water — boulder fields, rocky points, deep drop-offs into clear cold water. Tournament anglers often fish one program in the morning and the other in the afternoon depending on conditions.

Seasonal pattern

Spring (May–June). Champlain warms slowly. Pre-spawn smallmouth stage on rock points and sandy flats in shallow water starting in late May. Largemouth spawn in the southern bays as those warm earlier. Drop-shots and tubes for smallmouth; swim jigs and chatterbaits for largemouth.

Summer (July–August). The lake stratifies — surface temps in the upper 70s, deep water cold and oxygenated. Smallmouth go to deeper rock structure where they hunt alewives and gobies; drop-shots, ned rigs, and tube jigs dominate. Largemouth stay shallower in milfoil and pad fields with frogs and Texas rigs.

Fall (September–October). Cold fronts dominate the calendar. Between fronts, smallmouth crash bait on shallow rock; the bite turns on and off with the barometer. Suspending jerkbaits, blade baits, and swimbaits work the high-percentage windows.

Winter. Open water is short — ice covers most of the lake from January through March in average years.

Key structure

• Rocky reefs and points in the main basin — defining smallmouth structure
• Boulder fields, especially around the islands
• Milfoil flats and lily-pad bays in the southern arm and Missisquoi — largemouth cover
• Drowned timber in shallow southern bays
• Deep drop-offs to 60+ feet adjacent to shallow rock

Forage

Alewife are the dominant pelagic baitfish in the main basin and drive smallmouth movement seasonally. Round goby (an invasive) is an established forage for smallmouth on rock structure. Yellow perch, bluegill, and crayfish round out the system.

Access

Numerous public boat launches both states. Vermont side: Burlington, Charlotte, Vergennes, Mallet's Bay. New York side: Plattsburgh, Westport, Ticonderoga. Reciprocal fishing-license agreements exist between Vermont and New York for portions of the lake — read the current rules carefully because reciprocity does not cover every shoreline.

Regulations

Vermont and New York each manage their side of the lake. Always verify current rules with Vermont Fish & Wildlife and NY DEC before fishing — bag limits, seasons, and reciprocity terms shift over time.
