Individual boat ramp GPS coordinates are maintained under the jurisdiction of VT Parks & Wildlife Authority. Public boaters should verify seasonal launch water levels, gate hours, and daily vehicle/vessel fees before traveling.
Lake Memphremagog represents a significant aquatic resource in VT, providing vital water storage, wildlife habitat, and public recreation. Anglers target local sport species while boaters take advantage of established launch facilities around the perimeter. Observing safe boating speeds and biosecurity washdown procedures protects the fishery year-round.
Valid freshwater sport fishing license issued by Vermont Fish and Wildlife Department is required for anglers age 15+. Digital license on mobile is accepted.
Current motorized watercraft registration mandatory. Practice Clean, Drain & Dry protocols: drain all livewells and inspect props before launching. Life jackets required for all passengers.
Public shoreline and boating access managed by State & Local Authorities. Verify seasonal gate hours, launch fees, and parking rules before travel.
High-speed motorboating, pontoon cruising, wakeboarding, and water skiing across main channels. Target gamefish include Largemouth Bass, Pumpkinseed Sunfish, Yellow Perch, Rock Bass. Morning hours typically provide optimal glassy conditions for kayak and stand-up paddleboard (SUP) touring.
Warm water temperatures, peak swimming, active watersports, and open full-service campgrounds. Highest weekly attendance; plan early arrivals on summer weekends.
Spring pre-spawn and fall feeding transitions create prime trophy angling conditions. Cooler air, lower boat traffic, and vibrant seasonal shoreline foliage.
Northern cold winter conditions with freezing air temperatures and potential surface ice formation. Ramps and water systems may be winterized. Confirm open status before visiting.
