Marshall County Oklahoma Map — Madill Roads, Lake Texoma Shoreline, and Washita River Valleys

Marshall County sits in south-central Oklahoma, where Madill anchors the road network and Lake Texoma dominates the southern and eastern landscape. U.S. Highways 70, 177, and 377 converge around Madill, while Kingston provides a second major reference closer to the lake. The county’s shape is unusually tied to water: broad reservoir arms, narrow peninsulas, and the Washita River create a complicated shoreline that matters as much as the road grid. The maps can be viewed online, and the original high-resolution JPG files are available together in a downloadable ZIP for printing or closer inspection.

Lake Texoma also explains why the modern county looks different from its pre-1940s landscape. The Oklahoma Historical Society records that Denison Dam was completed in 1944, impounding the Red and Washita rivers and inundating a substantial amount of Marshall County land. The elevation map shows the physical side of that story: higher rolling ground remains across the northwest, while lake margins and major creek valleys occupy much lower terrain. Reading roads, water, and elevation together is especially useful here because shoreline geometry strongly affects travel and settlement.

Madill brings U.S. 70, 177, and 377 together in the county interior

Madill is the most useful starting point on the general county map. The Oklahoma Historical Society identifies it as the county seat and places the city at U.S. Highway 70, U.S. Highway 177/State Highway 199, and U.S. Highway 377/State Highway 99. Those routes make Madill the clearest road hub in Marshall County. From the city, Johnston County lies to the north, Love and Carter counties to the west, Bryan County to the east, and the Lake Texoma–Texas side to the south.

Oakland sits just northwest of Madill near U.S. 70, while U.S. 177 continues north toward Johnston County. U.S. 70 runs east past Madill toward Little City, and State Highway 106 provides another route toward the eastern lakeside. State Highway 32 leaves the western side toward Lebanon and Love County. With Madill fixed in the center, the northern and east-west road relationships become much easier to organize.

Kingston supplies the key southern reference. Roads leaving Madill converge again around Kingston before branching toward New Woodville, McBride, and the many Lake Texoma shoreline areas. The southern county boundary is not a simple survey line; it follows broad reservoir water and deeply indented shores. In Marshall County, a road map makes the most sense when the lake is treated as a major geographic feature rather than as background scenery.

Madill is the hub for three short straight-line city connections

The city-connections map uses Madill as the hub and links it with Oakland, Kingston, and New Woodville. The measurements are straight-line distances, not driving mileage. Oakland is shown about 2 miles from Madill, Kingston about 7 miles, and New Woodville about 10 miles. That compact set of connections makes it easy to see how the county’s main settlement area is concentrated around Madill and the northern edge of the Lake Texoma country.

Oakland is especially interesting because its proximity to Madill hides a different historical role. The Oklahoma Historical Society notes that Oakland developed earlier and once served as the seat of Pickens County in the Chickasaw Nation. Madill later became the dominant rail and county-seat town. The roughly two-mile direct connection on the map therefore links two places that represented different eras of local administration and commerce.

Kingston and New Woodville belong more directly to the reservoir landscape. Kingston is one of the county’s incorporated towns, while New Woodville works as a smaller geographic reference near the lake. Population-style numbers printed on the supplied graphic should be treated as map reference values rather than current estimates. Anyone who needs current population totals should use the latest U.S. Census Bureau data.

Lake Texoma and the Washita River reshape the southern and eastern county

Lake Texoma is the defining water feature in Marshall County. Its reservoir arms occupy much of the south and east, cutting deep bays into the land and creating long peninsulas. The Oklahoma Historical Society records that Denison Dam was completed in 1944 and that the new reservoir covered a substantial amount of county land. The irregular southern outline visible today is therefore a modern reservoir shoreline rather than the simple edge of an older land surface.

The Washita River approaches from the northeast and enters the Lake Texoma system near the county boundary. Glasses Creek and Little Glasses Creek form long interior valleys farther west. Little Hickory Creek and Hullum Creek divide the western side, while Briar Creek and Buncombe Creek descend through the central-southern interior. Rock Creek and Rooster Creek create additional low corridors closer to the southeastern lake arms.

Carter Lake and City Lake provide smaller inland references north and west of Madill, but the largest geographic effect comes from Lake Texoma itself. The Oklahoma Historical Society’s Lake Texoma history describes the reservoir as a Red River project built for flood control, hydropower, and other public purposes, with recreation becoming a major economic activity. Around Kingston and the southern county, the shoreline influences both settlement and the routes available between communities.

This water map is a geographic reference rather than a navigation, flood, or property product. It does not show current water level, depth, flood probability, boat hazards, marina conditions, or legal boundaries. Current U.S. Army Corps of Engineers, USGS, FEMA, state, and local information should be used for boating, flood planning, construction, or land-use decisions around Lake Texoma and the Washita River.

Elevation from about 175 to 310 meters separates northwest hills from lake lowlands

The elevation map gives Marshall County an actual range of about 175 to 310 meters, with a mean near 225 meters. The strongest brown and dark-tan terrain is concentrated in the northwest and west-central interior. Lake Texoma margins and major river valleys are much lower and appear in green. The overall range is about 135 meters, but closely spaced ridges and creek valleys create strong local relief across the county.

Northwest of Madill, the terrain rises into some of the county’s highest ground. Glasses Creek and smaller tributaries cut narrow lower channels through those hills. Oakland and Madill occupy an intermediate setting where uplands and creek valleys meet. The short distance between the two communities can look almost flat on a road map, but the relief map shows a more broken landscape around them.

South of Kingston and along the eastern reservoir edge, low terrain becomes much more extensive. Lake bays occupy the lowest areas, and Briar Creek and Buncombe Creek follow green valleys toward the water. The Washita River corridor in the northeast is similarly low. Short ridges still rise on many of the reservoir peninsulas, so the lakeside is not a uniform plain even where elevations are generally lower.

This generalized elevation surface is intended for county-scale comparison only. It should not be used to establish exact parcel elevation, road grade, drainage design, building elevations, or legal survey boundaries. Those uses require more precise source data and professional field measurements when appropriate.

Pickens County, railroads, and the 1908 county-seat vote shaped Madill

Before Oklahoma statehood, the area that became Marshall County was part of Pickens County in the Chickasaw Nation. Oakland developed as an early administrative and commercial center, while ranching and farming supported scattered communities. The Oklahoma Historical Society records that rail construction around 1900–1903 changed the settlement pattern and helped Madill grow into the county’s dominant town.

Marshall County was created at statehood in 1907. The county name honored the maiden name of the mother of George Henshaw, a Madill resident and delegate to the 1906 Oklahoma Constitutional Convention. In 1908 residents chose Madill over Kingston as the permanent county seat. That history adds context to the current road map, where Madill remains the strongest administrative and transportation focus even though the county’s population and recreation geography extends south toward the lake.

Lake Texoma produced another major transformation in the 1940s. The new reservoir inundated farmland and forced transportation changes, including the relocation of rail infrastructure. Recreation and tourism later became important parts of the county economy. The long shoreline around Kingston and New Woodville is therefore not simply a scenic feature; it records a twentieth-century project that physically reorganized land, travel routes, and local economic activity.

Use Madill to compare Kingston shoreline country with the Washita side

Madill connects the map layers particularly well. U.S. 70, 177, and 377 define the road location, Glasses Creek provides a nearby drainage reference, and the elevation map places the city between higher northwestern terrain and lower Lake Texoma country. Returning to Madill on each map makes it easy to see how transportation and physical geography overlap.

Heading south toward Kingston brings the reservoir into the foreground. The city-connections map places Kingston about 7 straight-line miles from Madill, but the terrain and water maps show why travel becomes more constrained farther south. Reservoir arms narrow the available land, and creek valleys reach deep into the shoreline. Roads must follow the remaining ridges and crossings rather than direct lines.

The northeast provides a different comparison. Little City and Cumberland lead toward the Washita River and the broad northeastern arm of Lake Texoma. Elevation drops into the river-and-reservoir lowland, creating a sharp contrast with the northwestern hills. Those differences make water and relief unusually important for understanding settlement in Marshall County.

Choose the Marshall County map that matches the question

For roads, towns, and the county outline, start with the general map. Find Madill first, use U.S. 70 for the east-west relationship, and then follow U.S. 177 and 377 for north-south orientation. Add Oakland, Kingston, and New Woodville once the main road framework is clear. The city-connections map is cleaner when the goal is simply to compare direct direction and spacing from Madill.

For water and terrain, begin with Lake Texoma and the Washita River, then add Glasses Creek, Buncombe Creek, and Briar Creek. Open the elevation map next and compare the same places. Higher northwestern uplands appear in brown, while reservoir margins and river valleys are lower and greener.
