A closed sky with even light today, with a proper ripple driven from the ENE and pressure leaking away. Most of the action on Upper Big Nemaha Reservoir G-37 should come off windblown banks where food collects. The productive run goes the day. Start on the obvious water and expand from there. Cooling water has fish active and on the move.

Gage County in Nebraska is where Upper Big Nemaha Reservoir G-37 sits. The ground round it is mixed forest. The water measures roughly 3 acres, so nothing here is far from anything else. It is one of the smaller waters we list in Gage County. Nearest town is Hickman, 12 miles off. Further out sit Beatrice (15 miles) and Wilber (19 miles). The county line runs close by, so rules can change within a short drive.
Our records carry no depth, so judge it from the bank. The old creek line under the surface is the feature worth finding. Held water runs deepest at the wall and shallows back to the inflow. Gage County records list common carp, flathead catfish, orangespotted sunfish, green sunfish and stonecat among the fish reported. County records show what lives in the area; the local agency holds the water-by-water list. On this water that means starting tight and working out.
Climate normals give 77°F for July and 23°F for January. A full turn of seasons, with the strongest sport on either side of summer. After mid March the shallows warm and the fish move up. Break-up near mid March, freeze-up near mid December: that is the shape of an average year. Fishing peaks soon after break-up and again before the cold returns. It sets the rhythm of the year at this water.
Nothing we hold confirms whether access is permitted. There is no mapped parking or launch close by, which usually means walking in. For the catfish, fish bottom baits into the deeper holes and let them sit. Season dates differ by species, so read the table. Fishing rules and camping rules are set separately here. Oir Reservoir 4-C sits 2.4 miles off and takes the overflow. Check the current arrangement for this water.
