• Where to Fish on Upper Big Nemaha Reservoir G-19

  Depth is not on record here, which means reading the ground instead. Levels move with the draw rather than the rain on water like this. Held water runs deepest at the wall and shallows back to the inflow. Johnson County records list common carp, green sunfish, johnny darter, bluegill and flathead catfish among the fish reported. Species recorded across the county may be limited to a few waters. On this water a short move beats a long cast.

• Seasonal Patterns

  The range across the year is 24°F to 77°F. Spring and autumn carry the fishing; summer and winter test it. Hard water holds through the cold months, breaking up near mid March. On the long-run averages the water opens up around mid March and starts locking again about mid December. September and October fish steadily right up to the freeze. That is the shape of the year on this water.

• Tackle & Baits

  There is no clear statement anywhere on who can fish it. We find no slipway, car park or made path within a short radius, so treat access as rough. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Parking is often the real limit rather than the bank itself. Signs go up and come down, so check on the day. Upper Big Nemaha Reservoir G-31 sits 0.7 miles off and takes the overflow. Nothing here settles the position at this water for certain.
