Upper Big Nemaha Reservoir 21-B is listed under Lancaster County, Nebraska. Pine and birch runs right down to the water. Around 48 acres of surface means several distinct areas to work. About 1.1 miles of bank, so nothing stays unexplored for long. Few waters listed in Lancaster County are bigger. Supplies mean a trip to Hickman, 9.1 miles off. Syracuse lies 18 miles off, Eagle another 19 miles. This one sits near enough to a boundary to be worth checking.
There is no published depth for this one, so start shallow and work out. Rip-rap along the wall holds fish that the open bank never does. A reservoir gives you a hard edge, a shelf, and not much else. Fish documented in Lancaster County include green sunfish, common carp, flathead catfish and bluegill. The county list is broader than any single water. At this water the water rewards a slow, careful approach.
Seasonal averages run from 23°F in January up to 77°F in July. Hard water is a season in its own right here. Ice fishing carries the winter, and the water opens about mid March. Climate figures give an open season running mid March to mid December. The middle of summer slows a little, with dawn and dusk carrying it. Anyone fishing this water regularly works to that calendar.
Nothing on record says whether the bank is open or closed. No made access is recorded, so a short walk in is the likely arrangement. For the catfish, fish bottom baits into the deeper holes and let them sit. Sort the permit out before you load the car. Where tickets apply, they are sold in the nearest town rather than on the bank. The nearest alternative is Upper Big Nemaha Reservoir L-10, 1.1 miles out. Rules at this water are worth checking on the day.
