4,135-acre reservoir near West Boylston. The lake tops out around 110 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Species by species, here's what the data says the year looks like.
On the chart, Wachusett Reservoir draws 4,013 acres inside 37.8 miles of shoreline, with 14 islands in the mix. With a shoreline index of 4.3, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 17% of this chart. Tip to tip the water measures near 5.6 mi with a 4.7-mi widest point. The water lies in Worcester County. Closest neighbour on DepthScout: East Waushacum Pond, 3 mi north of here.
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 15 to 35 ft. The spot to know is Main-lake point, a point in about 13 ft of water that rates prime for largemouth bass in fall. Warm-month bites cluster around early morning and the evening. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.

Spring bluegill concentrate at Back-bay flat, a prime-rated feeding flat around 5 ft. Warm-month bites cluster around early morning and the evening. A small sponge spider (fly) or a micro tube jig covers the summer program.

When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. If you only fish one area, make it Break off the point: a drop-off around 13 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
