25-acre lake in Worcester County, Massachusetts. The lake tops out around 15 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.
Traced from the shoreline, The Quag runs 25 acres with 0.8 miles of edge. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. The water lies in Worcester County. For a second option, West Waushacum Pond lies 0 mi east.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 5 to 15 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 15 ft | dawn & dusk | Back-bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Back-bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |

Early season chain pickerel use the shallows, holding in 2 to 10 ft. Expect a summer slide to 3 to 15 ft, then a winter hold in 4 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a weedless spoon + trailer or a buzzbait and you're in the game.
