2022 Map of Antelope Reservoir

About this map

Pierce sits at the southwestern edge of this landscape, a small settlement defined by its position along the Up railroad and an intricate network of irrigation systems. The area is heavily marked by water management infrastructure essential to the high plains, including the Lone Tree Ditch, Burger-Gault Lateral, and Pierce Lateral, which feed into local catchments like the Rowe Brothers Reservoir. To the north and east, the open expanse of the Pawnee National Grassland dominates the terrain, punctuated by natural drainage features such as Owl Cr and Little Owl Cr. Significant landmarks like Antelope Reservoir and Eastman Basin highlight the geographic character of Weld County, where the transition between public grasslands and managed agricultural water resources is clearly visible through the numerous named laterals and ditches that crisscross the prairie.
