138-acre reservoir in Sauk County, Wisconsin. The lake tops out around 38 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The season-by-season read for each species follows, from the map's own numbers.
On the chart, Dutch Hollow Lake draws 138 acres inside 5.6 miles of shoreline. A development index of 3.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 82% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 1.2 mi of water from one end to the other, 0.9 mi at the beam. The water lies in Sauk County. The nearest mapped water is Hemlock Slough, 2 mi to the east.
When the water first warms, walleye slide up into 4 to 15 ft. Summer is a 15 to 35 ft game here, winter an 11 to 38 ft one. Start at Deep basin. It's a deep basin holding about 32 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 | 4 to 15 ft | dusk & dawn | Main-lake point (10 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Deep basin (32 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 11 to 38 ft | dusk & night | Main-lake point (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 11 to 38 ft | dusk & dawn | Deep basin (32 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 15 to 35 ft. The spot to know is Shallow bay flat, a weed flat in about 5 ft of water that rates prime for largemouth bass in spring. Warm-month bites cluster around early morning and the evening. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (5 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (10 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (10 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Deep basin (32 ft) | Blade bait, Jigging spoon |
