233-acre reservoir in Washington County, Utah. The lake tops out around 16 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. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Kolob Reservoir runs 230 acres with 5 miles of edge, broken up by an island. An index of 2.4 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Roughly 95% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 1 mi, about 0.8 mi across. The water lies in Washington County. Closest neighbour on DepthScout: Navajo Lake, 16 mi east of here.
When the water first warms, cutthroat trout slide up into 3 to 15 ft. Summer is a 5 to 16 ft game here, winter a 4 to 16 ft one. Start at Break off the point. It's a drop-off holding about 7 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a trolled spoon (small) or an inline spinner rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 5 to 16 ft | dawn & dusk | Break off the point (7 ft) | Trolled spoon (small), Inline spinner |
| Fall | 3 to 16 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 4 to 16 ft | dawn | Break off the point (7 ft) | Small jigging spoon, Marabou jig |
In spring, rainbow trout run shallow here, mostly 4 to 16 ft. Summer keeps them at 4 to 16 ft, and they winter in 3 to 16 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 7 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 16 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 5 to 16 ft; cold water stacks them in 2 to 16 ft. Deep basin is the standout, a deep basin at roughly 14 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
