About this map

The Platte River valley defines the northern portion of this landscape, where a complex network of irrigation infrastructure supports the agricultural lands of Lincoln County. The Gothenburg Canal, Thirtymile Canal, and Tri-County Supply Canal dominate the hydrology, weaving across the flat terrain near Brady Island and the small settlement of Vroman. These canals represent the vital engineering efforts required to manage water in this region of Nebraska, carving through the transition between the river bottom and the dissected uplands to the south.

Sharp topographic contrast emerges south of the river valley as the terrain breaks into a series of deep ravines. Named features like Jeffrey Canyon, Gulch Canyon, and Gilman Canyon highlight this change in the land's character. For those researching local family history, the Gaslin Cem is a notable landmark located just south of Line Rd, offering a specific point of interest for genealogical study within this rural township structure.
