2,845-acre lake near Loup City. The lake tops out around 63 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Species by species, here's what the data says the year looks like.
The chart traces 20.3 miles of shoreline here. With a 2.1 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 61% of this chart. Figure 4.9 mi of water from one end to the other, 3.5 mi at the beam. It sits in Sherman County.

Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Sharp break is the standout, a drop-off at roughly 26 ft, rated prime for fall walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Rock reef (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Sharp break (26 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |

Come spring, look for crappie tight to the bank in 2 to 8 ft. They move out to 10 to 25 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 2 ft that scores prime in spring. Best bite is early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) is the honest summer answer here.

|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | 1/16 oz jig + tube, Curly-tail grub |

| Winter | 15 to 35 ft | midday | Sharp break (26 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |

You won't need more than a slab spoon or a small topwater (schooling fish) most summer days.
