About this map

The Tri-County Supply Canal serves as the hydraulic spine for this section of south-central Nebraska, where the borders of Dawson, Gosper, and Frontier counties meet. This intricate water management network is defined by a series of engineered storage sites, including Schilling Reservoir Number 1, Schilling Reservoir Number 2, and Keller Reservoir. These man-made features contrast with the natural erosion of Plum Creek Canyon and the winding course of Plum Cr, illustrating the intensive irrigation and power infrastructure required to support the region's agricultural economy.

Large-scale recreational and utility waters such as Johnson Lake, Gallagher Canyon, and the Elwood Reservoir dominate the landscape. The map details a precise grid of rural roads, such as RD 750 and Drive 746, which facilitate movement between the reservoirs and the surrounding farmland. This modern survey reflects the culmination of decades of water-rights development and land-use planning along the Platte River valley watershed.
