2022 Map of Bonny Reservoir South

About this map

The Bonny Reservoir and its surrounding drainage basin define this portion of the High Plains along the border of Yuma and Kit Carson counties. Fed by the South Fork Republican River, the reservoir is a central hydrologic feature supported by a complex network of smaller tributaries including Landsman Cr, Armknecht Cr, and Bonny Creek. The presence of the Hale Ditch Aqueduct and Hale Ditch in the northern sections illustrates the critical role of water management and irrigation in this semi-arid landscape. Historically, the area is dominated by the Public Land Survey System grid, which dictates the placement of rural roads like Co RD RR and Co RD 53. The terrain is characterized by the erosional patterns of ephemeral streams like Beaver Cr, which carve through the plains toward the Republican River valley.
