Overview
Quabbin Reservoir is the largest inland body of water in Massachusetts, covering about 38.6 square miles with a capacity of 412 billion gallons. Built between 1930 and 1939 by damming the Swift River Valley behind Winsor Dam and Goodnough Dike, it flooded the towns of Dana, Enfield, Greenwich and Prescott, and it filled by 1946. Together with Wachusett it supplies drinking water to Greater Boston. Because the watershed is protected forest, it is one of the wildest places in southern New England, home to bald eagles, loons, moose and bears.
Fishing
Quabbin holds the current Massachusetts state records for lake trout (25 lb 7 oz) and walleye (11 lb 0 oz). It's a premier coldwater fishery for lake trout and landlocked salmon, with excellent smallmouth bass too. Fishing is allowed only in designated areas, mostly in the northern part of the reservoir, under DCR's Quabbin rules.
Species
Lake trout, landlocked salmon, rainbow and brown trout, smallmouth and largemouth bass, chain pickerel, yellow and white perch, bullhead and other panfish. Smelt are an important forage.
Techniques
DCR's guide notes Gate 8 is best for deep coldwater trout and salmon, while Gates 31 and 43 offer more warmwater fishing. Troll lead core or downriggers for lakers in summer, or cast shorelines for salmon right after the season opens. For smallmouth, work rocky points and islands.
Seasons
Boat fishing runs on a set DCR season. For 2026 it was April 18 to October 17. Designated shoreline fishing areas stay open longer (through Dec. 31 in 2026). Early season is prime time for salmon and lake trout near the surface.
Hotspots
DCR boat launch areas: Gate 8 (BLA 1, coldwater), Gate 31 (BLA 2) and Gate 43 (BLA 3).
Regulations
MassWildlife freshwater regulations apply: https://www.mass.gov/freshwater-fishing-regulations. As a public water supply, this reservoir also has DCR access rules that are stricter than typical lakes; check both before you go. DCR Quabbin rules cover boat cleaning, motor horsepower limits, fishing areas and seasons.
Licensing
A Massachusetts fishing license is required (age 15+). DCR also sells a Quabbin fishing area season pass.
Access
Three DCR boat launch areas (Gates 8, 31 and 43) have rental boats on a first-come, first-served basis, and DCR runs a live availability dashboard. To prevent aquatic invasive species, private boats must go through DCR's cleaning/sealing program before launching. Most of the watershed is open on foot only, from gated access points. Quabbin Park, off Route 9 in Belchertown, is drive-in, with a visitor center, Enfield Lookout and an observation tower.
Boat ramps & launches
Gate 8 (BLA 1, Pelham), Gate 31 (BLA 2, New Salem) and Gate 43 (BLA 3, Hardwick/Petersham area). All are DCR-managed and seasonal.
Marinas & rentals
None. DCR rents boats at the three launch areas.
Amenities
