The complex irrigation network of Wyoming's high plains is meticulously detailed here, centered on the McNinch Number 1 Reservoir and its surrounding drainage systems. The landscape is defined by a sophisticated system of water management, where named waterways like the McNinch Supply Ditch, Barbara Budd Ditch, and the Redan Ditch Second Enlargement facilitate ranching and agriculture in a region marked by distinct topographic rises. High points such as Webster Hill, Sand Hill, and Rands Butte punctuate the terrain, providing natural landmarks above the winding paths of Middle Piney Cr and Beaver Cr. This area in Sublette County shows the persistent reliance on surface water infrastructure, evidenced by numerous named ditches including the Lehmer Ditch and Homer Ditch Number 2, which trace the contours of the land to sustain local operations far from major population centers.
