Rating depth structure for largemouth bass.
Shared by DepthScout anglers. Exact spots stay private, always.
6-acre reservoir in Dodge County, Wisconsin. The lake tops out around 12 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Species by species, here's what the data says the year looks like.
Crystal Lake maps at 6 acres behind 0.6 miles of shoreline. With a 1.8 development index there's bank structure worth casting at, in moderation. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. It sits in Dodge County. If the bite dies, Beaver Dam Lake is 6 mi to the northwest.
When the water first warms, largemouth bass slide up into 2 to 10 ft. Summer is a 4 to 12 ft game here, winter a 4 to 12 ft one. Start at Main-lake point. It's a point holding about 8 ft of water and rates prime come fall. The feeding windows run early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 12 ft | dawn & dusk | Break off the point (5 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 12 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 4 to 12 ft | midday | Break off the point (5 ft) | Blade bait, Jigging spoon |
