899-acre lake near Pottawattamie County. Iowa DNR survey water. The lake tops out around 24 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.
The drawn water covers 899 acres wrapped in 4.5 miles of bank. Nearly circular (index 1.1), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 95% of this chart. End to end it runs roughly 1.5 mi, about 1.2 mi across. It sits in Pottawattamie County. Its nearest charted neighbour, Carter Lake, is 0 mi to the south.
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 7 to 24 ft. If you only fish one area, make it Break off the point: a drop-off around 12 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.
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 (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (12 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 7 to 24 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (12 ft) | Blade bait, 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 7 to 24 ft. Start at Shallow bay flat. It's a weed flat holding about 1 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 | Shallow bay flat (1 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Dock / pier line (5 ft) | Small sponge spider (fly), Micro tube jig |

| Winter | 7 to 24 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (23 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, crappie slide up into 2 to 8 ft. Summer is a 7 to 24 ft game here, winter a 7 to 24 ft one. Start at Deep basin. It's a deep basin holding about 23 ft of water and rates prime come winter. 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.

| Spring | 2 to 8 ft | midday & dawn | Dock / pier line (5 ft) | 1/16 oz jig + tube, Curly-tail grub |

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 7 to 24 ft before dropping to 7 to 24 ft for winter. The spot to know is Deep basin, a deep basin in about 23 ft of water that rates prime for yellow perch in fall. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

Come spring, look for channel catfish tight to the bank in 3 to 12 ft. They move out to 7 to 24 ft in summer and finish the year down in 7 to 24 ft. If you only fish one area, make it Deep basin: a deep basin around 23 ft that scores prime in winter. Best bite is after dark and the evening.

| Spring | 3 to 12 ft | dusk | open water | |
| Summer | 7 to 24 ft chart-limited; documented 8 to 25 ft | night & dusk | Deep basin (23 ft) | |

In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 7 to 24 ft before dropping to 7 to 24 ft for winter. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 12 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

Carter Lake is about 24 ft (7 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, bluegill, crappie, yellow perch, channel catfish, walleye, smallmouth bass, white bass, common carp on Carter 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.
Break off the point is the top-rated area: a drop-off in about 12 ft of water that rates prime for largemouth bass in winter. The interactive chart above rates every spot for each 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 Carter 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.
