Rating depth structure for largemouth bass.

10-acre lake near FRANCONIA. The lake tops out around 15 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
PROFILE LAKE maps at 10 acres behind 0.5 miles of shoreline. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. Grafton County claims this one. Echo Lake sits 1 mi northwest — the closest neighbouring chart.
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 5 to 15 ft, and winter fish settle into 5 to 15 ft. The spot to know is Deep basin, a deep basin in about 15 ft of water that rates prime for yellow perch in fall. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: chain pickerel in 2 to 10 ft. As the season builds they drop to 3 to 15 ft, wintering in 4 to 15 ft. Top water on the chart: Break off the point, a drop-off in the 13 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a weedless spoon + trailer or a buzzbait gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Break off the point (13 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Break off the point (13 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 4 to 15 ft chart-limited; documented 5 to 18 ft | dawn | Break off the point (13 ft) | Jigging spoon (through ice) |
When the water first warms, largemouth bass slide up into 2 to 10 ft. By summer they slide out to 5 to 15 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Main-lake point: a point around 8 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 15 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (13 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (13 ft) | Blade bait, Jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. Summer is a 4 to 15 ft game here, winter a 5 to 15 ft one. Start at Deep basin. It's a deep basin holding about 15 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | open water | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 5 to 15 ft chart-limited; documented 6 to 18 ft | midday | Break off the point (13 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 15 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (15 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. Expect a summer slide to 5 to 15 ft, then a winter hold in 5 to 15 ft. Start at Main-lake point. It's a point holding about 8 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.

Spring white perch on PROFILE LAKE hold shallow, usually 4 to 15 ft. Depth-wise the year is flat: 5 to 15 ft in summer, 5 to 15 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 15 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a small spinner rig drifted or a 1/8 oz jigging spoon.

Deep basin is the top-rated area: a deep basin in about 15 ft of water that rates prime for yellow perch in fall. The interactive chart above rates every spot for each species and season.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
