About this map

Johnson Lake dominates this central Nebraska landscape, straddling the border between Dawson and Gosper counties. The lake's shoreline is defined by numerous recreational and geographic markers, from Mallard Beach and Mallard Cove on the western banks to the residential and service infrastructure around Kilby Point and the East Shore. The map reveals a complex hydraulic system managed through the Tri-County Supply Canal, which feeds several local basins including Lauhy Reservoir, Bossung Lake, and the larger Elwood Reservoir to the south.

Surface transportation is oriented around the water, with Plum Creek Pkwy providing a primary artery alongside a grid of rural roads like RD 749. Aviation access is noted at the Johnson Lake Airport, positioned near the northern narrows. The varied terrain along the lake is marked by distinct features such as North Point and Bullhead Point, illustrating how the mid-20th-century water projects transformed the Plum Creek drainage into a regional center for irrigation and recreation.
