Upper Big Nemaha Reservoir 2-A is listed under Johnson County, Nebraska. The ground around here is rolling bush. Surface area runs to about 15 acres — small enough to read in one session. It lies lower than most water we list in Nebraska. For supplies, Tecumseh is 14 miles out. Hickman follows at 15 miles, then Syracuse at 17 miles. A border sits close enough to be relevant to the paperwork.
We hold no survey for this water; read the slope of the shoreline instead. Draw-down through summer strips the margins, so follow the water out. The old creek line under the surface is the feature worth finding. Fish documented in Johnson County include common carp, green sunfish and johnny darter. The county list is broader than any single water. This water gives up more to patience than to distance.
Climate normals give 77°F for July and 23°F for January. Cold locks it up for a good stretch each year. Break-up comes around mid March, and the run that follows is short and strong. The season between ice runs from about mid March to mid December. The shoulder weeks of the open season are the productive ones. Plan around that when you fish this water.
Public data does not answer the access question here. There is no recorded infrastructure here; expect to find your own way in. A small crankbait along the drop and a worm in the thick stuff cover the bass. Sort the permit out before you load the car. Night access is frequently treated as a separate matter. For a change of water, Upper Big Nemaha Reservoir J-42 is 1.4 miles distant. For this water, the notice at the access point is the final word.
