819-acre lake near Griswold. The lake tops out around 18 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. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Pachaug Pond draws 847 acres inside 15.9 miles of shoreline, broken up by 3 islands. The 3.9 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Tip to tip the water measures near 3.5 mi with a 1.3-mi widest point. You'll find it in Southeastern Connecticut County. For a second option, Glasgo Pond lies 2 mi east.
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 5 to 18 ft; cold water stacks them in 5 to 18 ft. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| 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 18 ft | dawn & dusk | Break off the point (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Secondary point (4 ft) | Squarebill crankbait (shad), Spinnerbait |

Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.
