96-acre lake in Crawford County, Ohio. The lake tops out around 43 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. What follows comes from the same scoring engine that paints the spots above.
The drawn outline gives you 1.9 miles of bank to pick apart. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. 18% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.7 mi, about 0.4 mi across. It sits in Crawford County. Riley Reservoir sits 1 mi south — the closest neighbouring chart.
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shoreline break: a drop-off around 35 ft that scores prime in winter. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (9 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (9 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Shoreline break (35 ft) | Blade bait, Jigging spoon |
When the water first warms, crappie slide up into 2 to 8 ft. Summer is a 10 to 25 ft game here, winter a 15 to 35 ft one. Start at Back-bay flat. It's a feeding flat holding about 6 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (6 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Shallow bay flat (9 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow bay flat (9 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Deep basin (41 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 10 to 25 ft. Start at Back-bay flat. It's a feeding flat holding about 6 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Back-bay flat (6 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (9 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (9 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Shallow bay flat (9 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for channel catfish tight to the bank in 3 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 20 to 40 ft. If you only fish one area, make it Deep basin: a deep basin around 41 ft that scores prime in winter. Best bite is after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (9 ft) | |
| Summer | 8 to 25 ft | night & dusk | Shallow bay flat (9 ft) | |
| Fall | 10 to 30 ft | dusk | Shallow bay flat (9 ft) | |
| Winter | 20 to 40 ft | midday | Deep basin (41 ft) |

Outhwaite Reservoir is about 43 ft (13 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 Outhwaite 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.
Shoreline break is the top-rated area: a drop-off in about 35 ft of water that rates prime for largemouth bass in winter. The map above holds the full rated-spot list for every species and season.
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 Outhwaite Reservoir 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.
