8-acre lake in Iron County, Wisconsin. The lake tops out around 47 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Barrel Spring Lake runs 8 acres with 0.6 miles of edge. Nearly circular (index 1.4), so the story is the bottom, not the bank. About 29% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The water lies in Iron County. The nearest mapped water is Lake Dorothy, 0 mi to the southeast.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 15 to 35 ft. Fall largemouth bass concentrate at Main-lake point, a prime-rated point around 12 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Main-lake point (12 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (21 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (12 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (21 ft) | Blade bait, Jigging spoon |
