866-acre lake near Woodbury County. Iowa DNR survey water. The lake tops out around 11 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.
The drawn water covers 866 acres wrapped in 5.1 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 2.2 mi with a 0.9-mi widest point. Woodbury County claims this one. Its nearest charted neighbour, Browns Lake, is 3 mi to the north.
When the water first warms, largemouth bass slide up into 2 to 10 ft. By summer they slide out to 3 to 11 ft, and by winter most fish are in 3 to 11 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 2 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 (2 ft) | Spinnerbait, Chatterbait |
| Summer | 3 to 11 ft | dawn & dusk | Break off the point (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 11 ft | midday & dawn | Secondary point (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 3 to 11 ft | midday | Break off the point (3 ft) | Blade bait, Jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. Summer is a 3 to 11 ft game here, winter a 3 to 11 ft one. Start at Shallow bay flat. It's a weed flat holding about 2 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 | Shallow bay flat (2 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 3 to 11 ft | dawn & dusk | Shallow bay flat (2 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 3 to 11 ft | midday | Break off the point (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 11 ft | midday | Deep basin (10 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for crappie tight to the bank in 2 to 8 ft. Expect a summer slide to 3 to 11 ft, then a winter hold in 3 to 11 ft. Start at Deep basin. It's a deep basin holding about 10 ft of water and rates prime come winter. 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 (2 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 3 to 11 ft | dawn & dusk | Break off the point (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 3 to 11 ft | dawn | Break off the point (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 3 to 11 ft | midday | Deep basin (10 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: yellow perch sit in 3 to 11 ft that time of year. They don't go far with the seasons — 3 to 11 ft covers summer, 3 to 11 ft covers winter. The spot to know is Deep basin, a deep basin in about 10 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 11 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 11 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 11 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 11 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, channel catfish slide up into 3 to 11 ft. There's no big seasonal slide here — summer means 3 to 11 ft, winter 3 to 11 ft. If you only fish one area, make it Deep basin: a deep basin around 10 ft that scores prime in winter. In summer the feeding windows fall in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 11 ft | dusk | Shallow bay flat (2 ft) | |
| Summer | 3 to 11 ft | night & dusk | Deep basin (10 ft) | |
| Fall | 3 to 11 ft | dusk | Deep basin (10 ft) | |
| Winter | 3 to 11 ft | midday | Deep basin (10 ft) |

Snyder Bend Lake is about 11 ft (3 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, bluegill, crappie, yellow perch, channel catfish on Snyder Bend 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 2 ft of water that rates prime for largemouth bass in spring. 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.
