19-acre reservoir in Wasatch County, Utah. The lake tops out around 36 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The season-by-season read for each species follows, from the map's own numbers.
Mill Hollow Reservoir maps at 18 acres behind 0.8 miles of shoreline. Nearly circular (index 1.4), so the story is the bottom, not the bank. 39% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 0.3 mi, about 0.2 mi across. It sits in Wasatch County. Currant Creek Reservoir sits 11 mi south — the closest neighbouring chart.
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 7 to 36 ft. Put Break off the point first on the milk run — a drop-off near 16 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (16 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 36 ft | dawn | Break off the point (16 ft) | Jigging spoon, Tube jig (white) |
