34-acre pond near Union. CT DEEP survey water. 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.
Drawn out, this is 34 acres of water rimmed by 1.1 miles of bank. Nearly circular (index 1.4), so the story is the bottom, not the bank. Figure 0.5 mi of water from one end to the other. The water lies in Northeastern Connecticut County. Closest neighbour on DepthScout: Mashapaug Lake, 2 mi north of here.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. They don't go far with the seasons — 5 to 15 ft covers summer, 2 to 15 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 15 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |

Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
