1,525-acre reservoir in Windham County, Vermont. The lake tops out around 85 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Somerset Reservoir runs 1,540 acres with 20 miles of edge — 9 islands included. The 3.6 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 47% of the surface on the model — that's where the groceries are. Figure 4.7 mi of water from one end to the other, 1.5 mi at the beam. You'll find it in Windham County. The nearest mapped water is Grout Pond, 3 mi to the north.
In spring, bluegill run shallow here, mostly 1 to 6 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 10 to 25 ft for winter. Spring bluegill concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small sponge spider (fly) or a micro tube jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (6 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (72 ft) | Tungsten ice jig + plastic, Tiny spoon |
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Creek inflow is the standout, an inflow / creek mouth at roughly 8 ft, rated prime for spring brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Creek inflow (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Creek inflow (8 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Creek inflow (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Creek inflow (8 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 10 to 25 ft for winter. Spring brown bullhead concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Fish it in after dark and the evening and you'll meet the bite.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (6 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (6 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (6 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (72 ft) |
When the water first warms, chain pickerel slide up into 2 to 10 ft. Summer is a 3 to 15 ft game here, winter a 5 to 18 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a weedless spoon + trailer or a buzzbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (6 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow bay flat (6 ft) | Jigging spoon (through ice) |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 20 to 45 ft. Top water on the chart: Main-lake point, a point in the 21 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Creek inflow (8 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (21 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (21 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (38 ft) | Blade bait, Hair jig |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (38 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (72 ft) | Tungsten jig + spikes, Rattle spoon (small) |
