Dawson County lies in south-central Nebraska, where Lexington, Cozad, and Gothenburg line up along the broad Platte River corridor. The county changes quickly north of that lowland: Wood River, Buffalo Creek, Spring Creek, and many smaller tributaries cut through higher rolling terrain. The west, northwest, and southwestern edge rise well above the river plain, giving the county a much more varied surface than the highway corridor alone suggests. High-resolution map files are available for download in the section below.
This page explains the main settlements and roads, the ranked distribution of six communities, the Platte River and its channels and tributaries, and an elevation range of about 688 to 908 meters. The original high-resolution JPG versions of the supplied maps can also be downloaded together in a ZIP for printing, classroom use, or personal reference.

Lexington anchors a chain of Platte River towns across the county
Lexington is the Dawson County seat and the largest city in the county. The Nebraska Association of County Officials identifies Lexington as the county seat and lists Cozad and Gothenburg with it as the principal cities. On the supplied map, Lexington sits slightly east of center, making it a convenient reference between Cozad and Gothenburg to the west and Overton to the east.
The southern Platte corridor contains the densest concentration of towns, rail lines, and major roads. North of that corridor, settlement becomes sparse and stream valleys dominate the map. Sumner lies far to the northeast, while Farnam is near the southwestern edge, showing how much of the county extends beyond the main river-city belt.
History Nebraska records that Dawson County was officially organized in June 1871. The area had already served as a major westward travel corridor: the Oregon Trail followed the south side of the Platte, several Pony Express stations operated in what is now Dawson County, and Union Pacific crossed the area in 1867. Those successive transportation systems all used the same broad valley that still carries the county’s largest communities.
I-80, U.S. 30, and the railroad share the Platte River corridor
The strongest transportation line on the map follows the Platte River from west to east. I-80 and U.S. 30 connect Gothenburg, Cozad, Lexington, and Overton, and the railroad occupies the same broad lowland. Roads, towns, and rail infrastructure therefore cluster in one continuous corridor rather than being evenly distributed across the county.
Route 21 runs north from Lexington, while Route 283 continues south from the same area. Route 433 provides another north-south reference farther north, and Route 40 helps locate Sumner in the northeast. Around Gothenburg, Route 47 crosses the county, while Route 23 appears near Farnam at the southwest edge.
The road pattern is comparatively simple on the Platte plain, but it becomes more broken in the northern uplands where small stream valleys interrupt direct routes. The general map is useful for orientation, while current construction, closures, unpaved segments, and travel times should be checked with live Nebraska transportation information.
Six ranked communities emphasize the east-west river settlement pattern
The city distribution map ranks Lexington first, followed by Cozad, Gothenburg, Overton, Sumner, and Farnam. Lexington, Cozad, Gothenburg, and Overton form a long east-west sequence close to the Platte River and major transportation routes. Sumner and Farnam stand apart in the northeastern and southwestern interior.
No connector lines or mileage labels appear on the supplied city map. The useful comparison is therefore positional rather than numerical. The general road map is the better source for practical travel relationships, while the city view makes the concentration of settlement along the river corridor especially clear.
The values printed on the supplied map are 10,862 for Lexington, 3,937 for Cozad, 3,452 for Gothenburg, 689 for Overton, 353 for Sumner, and 257 for Farnam. They belong to the ranked-city graphic rather than a continuously updated demographic table. Current population figures should be checked with the U.S. Census Bureau or county sources when needed.
Platte River channels dominate the south while creeks descend from the uplands
The Platte River is the defining water feature across the southern part of Dawson County. Multiple channels spread through a broad lowland, and North Channel Platte River runs nearly parallel to the main river for a long distance. Lexington, Cozad, and Gothenburg sit close enough to this system that the relationship between water, transportation, and settlement is immediately visible.
Buffalo Creek descends across the central interior, while Spring Creek runs toward the Platte near Lexington. Elm Creek is prominent in the east, and Wood River crosses the northeastern side. Numerous short tributaries feed these larger streams from higher terrain, creating a heavily dissected northern landscape.
Gothenburg Canal appears in the west and Dawson County Canal farther east, adding irrigation features to the natural drainage network. Lake Helen, West Midway Lake, Central Midway Lake, and Gallagher Lake provide smaller standing-water references, while Johnson Lake is a prominent water body near the southern county line. The map is therefore useful for comparing natural channels, managed canals, and lakes in the same landscape.
This water map is intended for geographic reference. It does not define flood zones, legal water rights, parcel boundaries, channel depth, navigability, or public access. Those questions require current information from USGS and the responsible water-management agencies.
The Platte lowland sits more than 200 meters below the county’s highest uplands
The elevation map reports an actual county-wide range of approximately 688 to 908 meters, with a mean near 770 meters. The lowest green terrain follows the Platte River corridor across the south-central and eastern county, including the Lexington-to-Overton area. This broad lowland is the county’s most continuous flat surface.
Elevation rises toward the west and northwest, where tan and brown ridges are cut by many small streams. Another high zone appears near the southwestern edge. The total difference is about 220 meters, enough to create a strong contrast between the flat Platte corridor and the more rugged outer uplands.
Buffalo Creek and Spring Creek form lower green routes through the central-northern uplands, and Wood River creates another low corridor in the northeast. Comparing the water and elevation maps makes it easy to see how the named streams follow lower ground through otherwise elevated terrain.
The elevation colors are scaled locally for Dawson County and should be used to compare locations within this map. Similar shades on another county map may represent different absolute heights. The generalized surface is not survey-grade information for engineering, construction, drainage design, or property work.
Plum Creek became Lexington as the railroad town expanded
The Lexington area was originally known as Plum Creek. History Nebraska material explains that an earlier Plum Creek station stood south of the Platte on the Oregon Trail, but settlement shifted north when Union Pacific built its railroad across the county. By the early 1870s, the new town near the depot was adding homes, stores, hotels, schools, and churches.
Plum Creek was eventually renamed Lexington in 1889. The modern map still shows why the site prospered: Lexington is positioned close to the railroad, U.S. 30, I-80, and the Platte River corridor. Several generations of transportation infrastructure occupy essentially the same broad east-west lowland.
Oregon Trail, Pony Express, and Union Pacific all used the Platte corridor
History Nebraska describes Dawson County as a crossroads of westward migration. The Oregon Trail followed the south bank of the Platte, Pony Express stations operated in the area beginning in 1860, and Union Pacific crossed the county in 1867. Each system took advantage of the same broad river valley.
After the county was officially organized in 1871, permanent settlement accelerated and the rail corridor helped Lexington, Cozad, and Gothenburg grow into the county’s principal communities. The present map still concentrates the railroad, U.S. 30, I-80, and the largest towns along the Platte, making the historical continuity unusually visible.
Use the Platte corridor and northern uplands as two simple map anchors
For basic orientation, start at Lexington and follow U.S. 30 or I-80 west through Cozad and Gothenburg or east toward Overton. Then use Route 21 to move north into the creek-cut uplands. The city map provides a cleaner view of the same settlement pattern when minor roads are not needed.
For physical geography, begin with Platte River and North Channel Platte River, then trace Buffalo Creek and Spring Creek northward before moving to Wood River in the northeast. The elevation map adds the vertical context by showing the river corridor in green and higher outer terrain in tan and brown.
For printing or classroom display, the downloadable high-resolution JPG files preserve more road labels, creek names, canal labels, and local water features than the web previews. The county map emphasizes roads and settlements, the city map summarizes the ranked communities, the water map shows river and canal systems, and the elevation map highlights the contrast between the Platte plain and surrounding uplands.
Frequently Asked Questions
Does the city map show distances from Lexington to Cozad or Gothenburg?
No. The supplied city map ranks and locates Lexington, Cozad, Gothenburg, Overton, Sumner, and Farnam, but it does not include connector lines or mileage. Use the road map for relative position and a current routing service when actual driving distance is needed.
Where is the lowest terrain in Dawson County?
The broad Platte River and North Channel corridor across the south-central and eastern county contains the lowest terrain. The county-wide elevation range is about 688 to 908 meters, with higher ground becoming more common toward the west, northwest, and southwestern edge.
Can the Platte River map be used for flood decisions?
No. It is a geographic reference showing the Platte River, North Channel, Buffalo Creek, Spring Creek, canals, and lakes. Flood risk, water rights, parcel boundaries, current channel conditions, and access questions require current authoritative records.
