70-acre reservoir in Iron County, Wisconsin. The lake tops out around 12 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. What the data behind the map says about each species, season by season:
On the chart, Saxon Falls Flowage draws 70 acres inside 4.9 miles of shoreline, with a single island in the mix. With a shoreline index of 4.2, this water is all arms and coves — edge habitat well beyond its acreage. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Tip to tip the water measures near 0.8 mi with a 0.4-mi widest point. The water lies in Iron County. Closest neighbour on DepthScout: Weber Lake, 9 mi south of here.
When the water first warms, walleye slide up into 3 to 12 ft. There's no big seasonal slide here — summer means 4 to 12 ft, winter 4 to 12 ft. Start at Deep basin. It's a deep basin holding about 10 ft of water and rates prime come winter. The feeding windows run the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 4 to 12 ft | dusk & dawn | Main-lake point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 4 to 12 ft | dusk & night | Main-lake point (8 ft) | Jigging rap, Jig + big minnow |
| Winter | 4 to 12 ft | dusk & dawn | Deep basin (10 ft) | Jigging spoon + minnow head, Rattle bait |
When the water first warms, yellow perch slide up into 3 to 12 ft. There's no big seasonal slide here — summer means 4 to 12 ft, winter 4 to 12 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 12 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 12 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 12 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 4 to 12 ft, wintering in 4 to 12 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 4 to 12 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 12 ft | midday & dawn | Main-lake point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 12 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Spring puts muskellunge in skinny water — 3 to 12 ft is the zone. Summer fish stay in 4 to 12 ft, and winter fish hold in 4 to 12 ft. Spring muskellunge concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around the evening and early morning. A double-10 bucktail or a topwater (walk-the-dog / creeper) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (3 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 4 to 12 ft | dusk & dawn | Main-lake point (8 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 3 to 12 ft | midday & dusk | Main-lake point (8 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 4 to 12 ft | midday | Deep basin (10 ft) | Large rubber, crawled slow |

These come from the Wisconsin DNR's per-lake fish listing; where the DNR lists a group (panfish, catfish, trout) the specific species are resolved from Wisconsin's fish distribution by the lake's location, depth and habitat.
Deep basin is the top-rated area: a deep basin in about 10 ft of water that rates prime for walleye in winter. Scroll up to the map for the complete spot list by species and season.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
