1,496-acre reservoir in Juab County, Utah. The lake tops out around 23 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Mona Reservoir draws 1,580 acres inside 11.7 miles of shoreline. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 78% of this chart, as modeled. Figure 4.8 mi of water from one end to the other, 1.2 mi at the beam. You'll find it in Juab County. Closest neighbour on DepthScout: Salem Pond, 17 mi northeast of here.
Spring puts common carp in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 3 to 15 ft, wintering in 7 to 23 ft. Spring common carp concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | |
| Fall | 5 to 18 ft | midday | Old creek channel (12 ft) | |
| Winter | 7 to 23 ft | midday | Deep basin (20 ft) |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 7 to 23 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for largemouth bass in spring. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (10 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 7 to 23 ft | midday | Break off the point (10 ft) | Blade bait, Jigging spoon |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 7 to 23 ft; cold water stacks them in 7 to 23 ft. Top water on the chart: Main-lake point, a point in the 8 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 7 to 23 ft | dawn & dusk | Break off the point (10 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 7 to 23 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 7 to 23 ft | midday | Break off the point (10 ft) | Blade bait, Hair jig |
Come spring, look for walleye tight to the bank in 4 to 15 ft. Expect a summer slide to 7 to 23 ft, then a winter hold in 7 to 23 ft. Start at Currant Creek inflow. It's an inflow / creek mouth holding about 4 ft of water and rates prime come spring. Prime time lands in the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Currant Creek inflow (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 7 to 23 ft | dusk & dawn | Break off the point (10 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 7 to 23 ft | dusk & night | Break off the point (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 7 to 23 ft | dusk & dawn | Deep basin (20 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: white bass & hybrids sit in 3 to 15 ft that time of year. Warm water sends them out to 7 to 23 ft; cold water stacks them in 7 to 23 ft. Top water on the chart: Currant Creek inflow, an inflow / creek mouth in the 4 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a jigging spoon or a topwater (when schooling) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | midday & dawn | Currant Creek inflow (4 ft) | Rooster tail / inline spinner, Curly-tail jig (white/chartreuse) |
| Summer | 7 to 23 ft | dawn & dusk | Main-lake point (8 ft) | Jigging spoon, Topwater (when schooling) |
| Fall | 7 to 23 ft | midday & dawn | Main-lake point (8 ft) | Small blade bait, Jigging spoon |
| Winter | 7 to 23 ft | midday | Deep basin (20 ft) | Jigging spoon, Blade bait (vertical) |
