17-acre lake in Salt Lake County, Utah. The lake tops out around 36 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Lake Mary draws 16 acres inside 1 miles of shoreline. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. About 36% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. The water lies in Salt Lake County. Closest neighbour on DepthScout: Tibble Fork Reservoir, 8 mi south of here.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 16 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (16 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (9 ft) | Small spoon (orange), Spinner |

Spring puts lake trout in skinny water — 9 to 36 ft is the zone. Summer fish stay in 11 to 36 ft, and winter fish hold in 9 to 36 ft. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 31 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 36 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon over shoals, Jerkbait (shallow) |
