103-acre lake near Washington County. The lake tops out around 20 ft. The depth data here comes from the Minnesota DNR survey of 1979, a decades-old survey (the DNR's original lake-survey map). What the data behind the map says about each species, season by season:
Traced from the shoreline, Long runs 103 acres with 3.5 miles of edge. An index of 2.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 96% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 1.1 mi, about 0.4 mi across. You'll find it in Washington County. Closest neighbour on DepthScout: Lily, 1 mi east of here.
Spring walleye on Long hold shallow, usually 4 to 15 ft. By summer they slide out to 6 to 20 ft, and by winter most fish are in 6 to 20 ft. The chart's best answer is Deep basin — deep basin, 20 ft, prime for winter. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (3 ft) | 1/8 oz jig + minnow, Hair jig |

Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Warm water sends them out to 4 to 15 ft; cold water stacks them in 6 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (5 ft) | Micro jig + waxworm, Small spoon tipped |
