23-acre lake in Utah. The lake tops out around 39 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What the data behind the map says about each species, season by season:
The outline encloses 23 acres, worked by 0.9 miles of shoreline. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. 27% 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. Its nearest charted neighbour, Moon Lake, is 15 mi to the southeast.
Spring rainbow trout on Dean Lake hold shallow, usually 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 39 ft. The chart's best answer is Break off the point — drop-off, 18 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (10 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (18 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 39 ft | dawn | Break off the point (18 ft) | Jigging spoon, Tube jig (white) |
In spring, brown trout run shallow here, mostly 3 to 25 ft. Midsummer fish sit out in 12 to 39 ft before dropping to 5 to 35 ft for winter. Summer brown trout concentrate at Break off the point, a prime-rated drop-off around 18 ft. Fish it in after dark and early morning and you'll meet the bite. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (10 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 12 to 39 ft | night & dawn | Break off the point (18 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (10 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (18 ft) | Jigging spoon, Small stickbait (slow) |
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 18 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (18 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (10 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (18 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 5 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (18 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (33 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (33 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 33 ft.
