161-acre lake near Lenawee County. The lake tops out around 22 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. Below is the species-by-species picture, pulled from the same data the map uses.
Lake Adrian's chart carries 2.2 miles of bank. With a 1.5 development index there's bank structure worth casting at, in moderation. Roughly 98% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 0.8 mi end to end and 0.5 mi across at its widest. It sits in Lenawee County. If the bite dies, Sand Lake is 10 mi to the northwest.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 7 to 22 ft before dropping to 7 to 22 ft for winter. The spot to know is Back-bay flat, a weed flat in about 11 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (11 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 7 to 22 ft | dawn | Deep basin (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 22 ft | midday | Deep basin (19 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 22 ft | midday & dawn | Deep basin (19 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. Summer is a 7 to 22 ft game here, winter a 7 to 22 ft one. Start at Secondary point. It's a point holding about 6 ft of water and rates prime come fall. The feeding windows run early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Secondary point (6 ft) | Ned rig, Tube jig |

Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 7 to 22 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 2 ft that scores prime in spring. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Back-bay flat (11 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
