Look for Upper Big Nemaha Reservoir 13-A in Lancaster County, Nebraska. It sits in mixed forest. The water measures roughly 9 acres, so nothing here is far from anything else. The closest town, Hickman, is 4.7 miles distant. Beyond it, Crete at 16 miles and Wilber at 17 miles. The boundary is near enough that local access rules are worth double-checking.
No depth figure has reached our records, which makes a plummet useful. Inflow corners move water, and moving water gathers fish. Points where the flooded channel swings in are the reliable ones. Records held for Lancaster County cover green sunfish, common carp, flathead catfish and bluegill. It is the county picture; the agency list is water-specific. This water fishes better once you know its edges.
Long-run averages give July about 77°F and January about 23°F. Cold winters and warm summers give a wide working range. Count the season from break-up, usually mid March. Averages suggest open water from about mid March through to roughly mid December. The shoulder weeks of the open season are the productive ones. Plan any trip to this water around it.
Our records carry no access rule either way. The map shows no ramp or car park nearby, so this is a walk-in water. For the catfish, fish bottom baits into the deeper holes and let them sit. Rules differ from one water to the next round here. Some ground is open by custom rather than by right, so tread carefully. Should this one be busy, Big Nemaha Reservoir G-18 is 2.9 miles off. For this water in particular, ask before you travel.
