319-acre lake near Worth County. Iowa DNR survey water. The lake tops out around 7 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. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 319 acres of water rimmed by 2.7 miles of bank. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Tip to tip the water measures near 1.1 mi with a 0.6-mi widest point. You'll find it in Worth County. Closest neighbour on DepthScout: Bear, 6 mi northwest of here.
Spring puts largemouth bass in skinny water — 1 to 7 ft is the zone. Summer fish stay in 2 to 7 ft, and winter fish hold in 2 to 7 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 7 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 7 ft | dawn & dusk | Shallow bay flat (2 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 7 ft | midday & dawn | Main-lake point (2 ft) | Squarebill crankbait (shad), Spinnerbait |

Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Warm water sends them out to 2 to 7 ft; cold water stacks them in 2 to 7 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.
