About this map

The South Platte River carves a wide, braided path through the southeastern corner of this landscape, anchoring the settlement of Iliff and the nearby siding of Griff. This region is defined by an intricate network of early 21st-century irrigation infrastructure, where the Iliff Ditch and Iliff Platte Valley Ditch divert water to support high-plains agriculture. Further north, the North Sterling Outlet Canal snakes across the terrain, supplemented by numerous laterals that trace the property lines of Logan County’s grid-patterned roads.

Water management is the dominant human imprint on the land, evidenced by features such as the Breidenbach Dam and Breidenbach Reservoir, as well as named stock ponds like McKenzie Pond and Larson Pond. Lewis Creek and its many branches provide natural drainage, while the various numbered laterals, including the Gillette Number 28 Lateral, show the precision of modern water rights and distribution essential for this river-valley community.
