2010 Map of Bonny Reservoir South

About this map

Bonny Reservoir dominates the northern edge of this high plains landscape, formed by the construction of Bonny Dam on the South Fork Republican River. This 2010 survey illustrates the managed water systems of Yuma County, featuring the irrigation infrastructure of the Hale Ditch and the secondary O'Brien Number 1 Dam. The surrounding area is defined by a rigorous grid of county roads that carve through the prairie, providing access to Bonny State Park. Several vital waterways, including Landsman Creek, Bonny Creek, and Beaver Creek, feed into the reservoir system, showing the critical role of water management in this eastern Colorado terrain. The map's detailed road network, from County Rd RR to County Rd KK, reveals the systematic division of land typical of the region's agricultural and recreational development.
