348-acre lake near Lyon County. The lake tops out around 10 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. What the data behind the map says about each species, season by season:
The drawn water covers 348 acres wrapped in 5 miles of bank. With a 1.9 development index there's bank structure worth casting at, in moderation. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Figure 1.4 mi of water from one end to the other, 1 mi at the beam. Lyon County claims this one. Its nearest charted neighbour, Lady Slipper, is 2 mi to the northwest.
Spring puts walleye in skinny water — 3 to 10 ft is the zone. Summer fish stay in 3 to 10 ft, and winter fish hold in 3 to 10 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 8 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | dusk & dawn | Main-lake point (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 3 to 10 ft | dusk & dawn | Break off the point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 3 to 10 ft | dusk & night | Break off the point (8 ft) | Jigging rap, Jig + big minnow |
| Winter | 3 to 10 ft | dusk & dawn | Deep basin (10 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 3 to 10 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 10 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 10 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 10 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for crappie tight to the bank in 2 to 8 ft. Expect a summer slide to 3 to 10 ft, then a winter hold in 3 to 10 ft. Start at Deep basin. It's a deep basin holding about 10 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 3 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 3 to 10 ft | dawn | Shallow bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 3 to 10 ft | midday | Deep basin (10 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Early season common carp use the shallows, holding in 2 to 10 ft. Even in summer they hold at 2 to 10 ft; winter keeps them in 3 to 10 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | |
| Summer | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | |
| Fall | 3 to 10 ft | midday | Shallow bay flat (3 ft) | |
| Winter | 3 to 10 ft | midday | Deep basin (10 ft) |
