80-acre lake near Dodge County. Nebraska Game and Parks Commission survey water. The lake tops out around 18 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. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 80 acres, worked by 1.6 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 64% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 0.7 mi, about 0.2 mi across. Dodge County claims this one. Its nearest charted neighbour, Fremont Lake 16, is 0 mi to the northwest.
Come spring, look for rainbow trout tight to the bank in 5 to 18 ft. Through summer count on 5 to 18 ft; the winter hold is 4 to 18 ft. If you only fish one area, make it Break off the point: a drop-off around 15 ft that scores prime in winter. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.

|---|---|---|---|---|
| Spring | 5 to 18 ft | dawn & dusk | Main-lake point (7 ft) | Inline spinner (silver), Small spoon |

The summer box starts with a double-10 bucktail or a topwater (walk-the-dog / creeper).
