14,000-acre border reservoir near Andover. Walleye and muskie across the Ohio-Pennsylvania line. 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. Species by species, here's what the data says the year looks like.
Pymatuning Reservoir maps at 14,334 acres behind 69.7 miles of shoreline — 8 islands included. With a shoreline index of 4.2, this water is all arms and coves — edge habitat well beyond its acreage. 70% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 12.8 mi with a 5.9-mi widest point. Crawford County claims this one. Its nearest charted neighbour, Conneaut Lake, is 10 mi to the east.
When the water first warms, largemouth bass slide up into 2 to 10 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 10 to 33 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 7 ft that scores prime in spring. 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 | Shallow bay flat (7 ft) | Spinnerbait, Chatterbait |
| Summer | 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 (12 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 10 to 33 ft | midday | Old creek channel (19 ft) | Blade bait, Jigging spoon |
Come spring, look for crappie tight to the bank in 2 to 8 ft. Expect a summer slide to 10 to 25 ft, then a winter hold in 10 to 33 ft. Start at Old creek channel. It's a creek channel holding about 19 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) is the honest summer answer here.
| 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 | 10 to 25 ft | dawn & dusk | Old creek channel (19 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Old creek channel (19 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 10 to 33 ft | midday | Deep basin (28 ft) | Tungsten jig + soft plastic, Tiny 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 10 to 25 ft one. Start at Back-bay flat. It's a weed flat holding about 5 ft of water and rates prime come spring. 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 | Back-bay flat (5 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 | 6 to 18 ft | midday | Shallow bay flat (7 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (28 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, channel catfish slide up into 3 to 12 ft. By summer they slide out to 8 to 25 ft, and by winter most fish are in 10 to 33 ft. If you only fish one area, make it Creek inflow: an inflow / creek mouth around 3 ft that scores prime in spring. In summer the feeding windows fall in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Creek inflow (3 ft) | |
| Summer | 8 to 25 ft | night & dusk | Old creek channel (19 ft) | |
| Fall | 10 to 30 ft | dusk | Old creek channel (19 ft) | |
| Winter | 10 to 33 ft | midday | Deep basin (28 ft) |
Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 10 to 33 ft, wintering in 10 to 33 ft. Spring walleye concentrate at Creek inflow, a prime-rated inflow / creek mouth around 5 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Creek inflow (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 10 to 33 ft | dusk & dawn | Main-lake point (12 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 10 to 33 ft | dusk & night | Main-lake point (12 ft) | Jigging rap, Jig + big minnow |
| Winter | 10 to 33 ft | dusk & dawn | Deep basin (28 ft) | Jigging spoon + minnow head, Rattle bait |
When the water first warms, muskellunge slide up into 3 to 12 ft. Summer is an 8 to 25 ft game here, winter a 10 to 33 ft one. Start at Shallow bay flat. It's a weed flat holding about 7 ft of water and rates prime come spring. The feeding windows run the evening and early morning. Keep a double-10 bucktail or a topwater (walk-the-dog / creeper) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (7 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 8 to 25 ft | dusk & dawn | Main-lake point (12 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
