130-acre lake in Huron County, Ohio. The lake tops out around 33 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. The season-by-season read for each species follows, from the map's own numbers.
There are 2.5 miles of drawn shoreline to work. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. 24% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 0.9 mi long by 0.6 mi wide at the broadest reach. The water lies in Huron County. The nearest mapped water is Wellington South Reservoir, 11 mi to the northeast.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 10 to 33 ft. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 8 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (8 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 10 to 33 ft | midday | Break off the point (27 ft) | Blade bait, Jigging spoon |
In spring, crappie run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 10 to 25 ft, and winter fish settle into 10 to 33 ft. Deep basin is the standout, a deep basin at roughly 33 ft, rated prime for winter crappie. Time it for early morning and the evening. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (8 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Back-bay flat (10 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow bay flat (8 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 10 to 33 ft | midday | Deep basin (33 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Summer pushes them deeper, 4 to 15 ft, and winter fish settle into 10 to 25 ft. The spot to know is Shallow bay flat, a weed flat in about 8 ft of water that rates prime for bluegill in summer. Warm-month bites cluster around early morning and the evening. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (8 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (8 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (8 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Back-bay flat (10 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring puts channel catfish in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 8 to 25 ft, wintering in 10 to 33 ft. Winter channel catfish concentrate at Deep basin, a prime-rated deep basin around 33 ft. Warm-month bites cluster around after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (8 ft) | |
| Summer | 8 to 25 ft | night & dusk | Break off the point (27 ft) | |
| Fall | 10 to 30 ft | dusk | Deep basin (33 ft) | |
| Winter | 10 to 33 ft | midday | Deep basin (33 ft) |

New London Reservoir is about 33 ft (10 m) deep at its deepest point. The depth chart here comes from real state fisheries GPS surveys, so the contours reflect measured depths.
Anglers target largemouth bass, crappie, bluegill, channel catfish on New London Reservoir. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Shallow bay flat is the top-rated area: a weed flat in about 8 ft of water that rates prime for largemouth bass in spring. Every other rated spot, per species and season, is on the map above.
For largemouth bass, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
