17-acre lake near Cass County. The lake tops out around 14 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Cold Springs Lake maps at 17 acres behind 0.6 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. It sits in Cass County. If the bite dies, Cocklin Fish Farm is 4 mi to the southwest.
When the water first warms, crappie slide up into 2 to 8 ft. Summer is a 4 to 14 ft game here, winter a 4 to 14 ft one. Start at Deep basin. It's a deep basin holding about 14 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.
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 | Dock / pier line (2 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 4 to 14 ft chart-limited; documented 10 to 25 ft | dawn & dusk | Break off the point (10 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 4 to 14 ft chart-limited; documented 8 to 20 ft | dawn | Break off the point (10 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 4 to 14 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (14 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 14 ft, then a winter hold in 4 to 14 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.

|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (1 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 14 ft chart-limited; documented 4 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Small sponge spider (fly), Micro tube jig |

| Winter | 4 to 14 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (14 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 4 to 14 ft in summer and finish the year down in 4 to 14 ft. If you only fish one area, make it Break off the point: a drop-off around 10 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 (1 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 14 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (10 ft) | Texas-rigged 10" worm, Deep-diving crankbait |

| Winter | 4 to 14 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (10 ft) | Blade bait, Jigging spoon |
Come spring, look for channel catfish tight to the bank in 3 to 12 ft. They move out to 4 to 14 ft in summer and finish the year down in 4 to 14 ft. If you only fish one area, make it Deep basin: a deep basin around 14 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 | open water | |
| Summer | 4 to 14 ft chart-limited; documented 8 to 25 ft | night & dusk | Deep basin (14 ft) | |
| Fall | 4 to 14 ft chart-limited; documented 10 to 30 ft | dusk | Deep basin (14 ft) | |
| Winter | 4 to 14 ft chart-limited; documented 20 to 40 ft | midday | Deep basin (14 ft) |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 4 to 14 ft before dropping to 4 to 14 ft for winter. The spot to know is Deep basin, a deep basin in about 14 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.

In spring, walleye run shallow here, mostly 4 to 14 ft. Summer keeps them at 4 to 14 ft, and they winter in 4 to 14 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 10 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.

Cold Springs Lake is about 14 ft (4 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 on Cold Springs 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 14 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 Cold Springs 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.
