27-acre lake near Taylor County. The lake tops out around 16 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 27 acres of water rimmed by 0.8 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. You'll find it in Taylor County. Closest neighbour on DepthScout: Lake of Three Fires, 7 mi east of here.
In spring, crappie run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 5 to 16 ft before dropping to 5 to 16 ft for winter. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 15 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.
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 8 ft | midday & dawn | Shallow bay flat (2 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 5 to 16 ft chart-limited; documented 10 to 25 ft | dawn & dusk | Break off the point (6 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 16 ft chart-limited; documented 8 to 20 ft | dawn | Break off the point (6 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 16 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (15 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Warm water sends them out to 4 to 15 ft; cold water stacks them in 5 to 16 ft. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.

Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 5 to 16 ft; cold water stacks them in 5 to 16 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.

Spring puts channel catfish in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 5 to 16 ft; cold water stacks them in 5 to 16 ft. Deep basin is the standout, a deep basin at roughly 15 ft, rated prime for winter channel catfish. Plan around after dark and the evening in the warm months.

Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 5 to 16 ft game here, winter a 5 to 16 ft one. The chart's best answer is Deep basin — deep basin, 15 ft, prime for fall. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.

Spring walleye on Windmill Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 5 to 16 ft, and by winter most fish are in 5 to 16 ft. The chart's best answer is Break off the point — drop-off, 6 ft, prime for fall. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).

Windmill Lake is about 16 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 crappie, bluegill, largemouth bass, channel catfish, yellow perch, walleye, common carp on Windmill 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.
Deep basin is the top-rated area: a deep basin in about 15 ft of water that rates prime for crappie in winter. The interactive chart above rates every spot for each species and season.
For crappie, 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 Windmill Lake is regulated by the Iowa DNR. Check the official Iowa regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
