Rating depth structure for largemouth bass.
Recent public catches load as you reach this section.
69-acre lake in Fulton County, Ohio. 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 follows comes from the same scoring engine that paints the spots above.
There are 3.1 miles of drawn shoreline to work. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Tip to tip the water measures near 1 mi with a 0.4-mi widest point. Fulton County claims this one. Its nearest charted neighbour, Archbold Reservoir Number One, is 9 mi to the southeast.
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 5 to 15 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 7 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
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 | 2 to 10 ft | dawn & dusk | Shallow bay flat (7 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 15 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (7 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (10 ft) | Blade bait, Jigging spoon |
Spring crappie on Harrison Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 5 to 15 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Deep basin — deep basin, 15 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a jig trolled/spider-rigged or a small crankbait (trolled).

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (7 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 5 to 15 ft chart-limited; documented 10 to 25 ft | dawn & dusk | Shallow bay flat (7 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 15 ft chart-limited; documented 8 to 20 ft | dawn | Shallow bay flat (7 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (15 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring bluegill on Harrison Lake hold shallow, usually 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 5 to 15 ft. Put Back-bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a small sponge spider (fly) or a micro tube jig.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Back-bay flat (2 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (7 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 5 to 15 ft chart-limited; documented 6 to 18 ft | midday | Shallow bay flat (7 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 |
Early season channel catfish use the shallows, holding in 3 to 12 ft. Expect a summer slide to 5 to 15 ft, then a winter hold in 5 to 15 ft. Put Deep basin first on the milk run — a deep basin near 15 ft that grades prime for winter. In summer the feeding windows fall in after dark and the evening.

Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 15 ft.

Harrison Lake is about 15 ft (5 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target largemouth bass, crappie, bluegill, channel catfish on Harrison Lake. 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 7 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.
Fishing on Harrison Lake is regulated by the Ohio DNR Division of Wildlife. Check the official Ohio regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
