441-acre reservoir near Laramie Region. The lake tops out around 12 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 397 acres of water rimmed by 7.3 miles of bank. An index of 2.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The basin spans about 1.3 mi end to end and 1.1 mi across at its widest. You'll find it in Goshen County. Closest neighbour on DepthScout: Springer Res, 2 mi northeast of here.
Spring puts crappie in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 4 to 12 ft; cold water stacks them in 4 to 12 ft. Deep basin is the standout, a deep basin at roughly 10 ft, rated prime for winter crappie. Plan around early morning and the evening in the warm months. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 4 to 12 ft | dawn & dusk | Break off the point (5 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 4 to 12 ft | dawn | Break off the point (5 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 4 to 12 ft | midday | Deep basin (10 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
In spring, channel catfish run shallow here, mostly 3 to 12 ft. Summer keeps them at 4 to 12 ft, and they winter in 4 to 12 ft. Winter channel catfish concentrate at Deep basin, a prime-rated deep basin around 10 ft. Fish it in after dark and the evening and you'll meet the bite.

The spring pattern is a shallow one: bluegill in 1 to 6 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 4 to 12 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for bluegill in spring. Plan around early morning and the evening in the warm months. Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |

Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.

|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |

Early season walleye use the shallows, holding in 3 to 12 ft. Even in summer they hold at 4 to 12 ft; winter keeps them in 4 to 12 ft. Put Break off the point first on the milk run — a drop-off near 5 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
