Reagan County Map users can start with one simple geographic fact: Big Lake is shown in the southern part of the county rather than near its exact center. This page brings together the county and road map, the ranked city map, the water and terrain map, and the elevation map. The same set is also available below as a high-resolution A3 JPG ZIP download for printing or offline reference.
Reagan County covers a broad part of West Texas where settlements are widely spaced. On the supplied maps, roads and place labels become noticeably denser around Big Lake, while much of the central and northern county is more open. That pattern makes it useful to compare several map views instead of relying on one general map. The road map explains how places connect, the city map shows how strongly the major settlement pattern is concentrated, and the water and elevation maps reveal the drainage and relief that are easy to miss on a simple boundary map.
Several details stand out immediately: U.S. 67 and State Highway 137 meet near Big Lake, Slager Lake appears in the northwest, Corral Creek and Indian Creek are labeled in the northeast, Live Oak Creek is marked near the southwest edge, and the highest ground on the elevation surface is concentrated in the southwest. Those features give this Reagan County page a more specific purpose than a generic county outline.

Big Lake, the road network, and the shape of the county
The general county map places Big Lake close to the southern part of Reagan County. Texon is labeled to the west, Witco appears southeast of Big Lake, and Crossroads is shown much farther north. The spacing between those labels is important because it shows how different Reagan County is from a densely urban county. A large amount of land separates the named communities, while Big Lake has the clearest concentration of roads and local labels.
Two routes are especially easy to follow. U.S. 67 crosses the Big Lake area from west toward the southeast, while State Highway 137 runs north-south through the city. The map also shows numbered routes including 113, 22, 50, 56, 101, and 123. These are useful for understanding direction and countywide connections, although this map is not intended to replace a turn-by-turn road map or current navigation service.
The surrounding counties help place Reagan County within West Texas. The city map labels Glasscock County to the north, Irion County and Midland County on the eastern side, Tom Green County to the southeast, and Sterling, Upton, and Crockett counties along the western and southwestern sides. Seeing those neighbors is useful when comparing regional routes or looking at a place that lies close to a county boundary.
The ranked city map is dominated by Big Lake
The city map is deliberately much simpler than the general map. Its city index contains one ranked major city, Big Lake, with a displayed value of 2,990. That figure should be read as the value printed on the supplied map rather than as a promise that it matches every newer population estimate. For the purpose of this article, the more important point is the settlement pattern: Big Lake is the only place given a ranked-city symbol on this map.
Big Lake also sits well south of the county’s midpoint. The northern half of the map contains no comparable ranked city marker, and the main city symbol lies where the southern road network becomes more concentrated. This makes the map useful for explaining why Reagan County can look almost empty at first glance. The county is large, but its principal mapped urban focus occupies a relatively small part of that area.
It helps to compare this view with the general county map. The general map includes smaller place labels such as Texon, Witco, and Crossroads, while the ranked city map uses a narrower definition and emphasizes only Big Lake. The two maps therefore serve different purposes. Use the general map when you need more named reference points, and use the city map when you want a quick view of the county’s main settlement concentration.
Slager Lake and a network of mostly small creeks
The terrain and water map does not show one large river or reservoir dominating Reagan County. Instead, numerous small channels branch across the county. Slager Lake is labeled in the northwest. Corral Creek and Indian Creek are named near the northeastern corner, while Live Oak Creek is marked close to the southwestern boundary. Many additional channels appear without labels, especially across the eastern and central parts of the map.
The northeast is particularly dissected by branching drainage lines. Farther west, some areas have noticeably fewer mapped channels, although the southwest and south still contain a number of narrow drainages. Near the southern part of the county, the name Big Lake appears close to the town area as well. Because the map is designed as a terrain-and-water reference, it should not be treated as a flood-risk map, a navigation chart, or a legal description of water rights.
This map becomes more useful when placed beside the road map. Roads are visually concentrated around Big Lake and several county corridors, while drainage lines spread more widely through low ground across the county. Keeping those themes separate prevents the map from becoming too crowded and makes it easier to choose the right graphic for a report, lesson, or printed reference sheet.
Elevation rises toward the southwest and falls into eastern drainages
The supplied elevation map reports an actual range of approximately 720 to 902 meters, with a mean elevation of 809 meters. The color surface shows that Reagan County is not one perfectly flat plain. Darker brown shades representing the highest ground are concentrated in the southwest, and moderately high terrain continues across parts of the south. Those areas contrast clearly with the green lower terrain farther east.
Low ground is especially noticeable along the branching valleys in the east and northeast. A broad lower corridor also reaches across parts of the center, creating a visible connection between the elevation surface and the creek network shown on the water map. The relationship is useful for understanding why so many drainage lines branch through the eastern half of the county. The relief is not mountainous in the way a far-west Texas mountain county would be, but the internal change in elevation is still easy to see.
This elevation layer is best used for countywide comparison, not engineering work. It can help answer questions such as which side of the county is generally higher, where drainage valleys cut into the terrain, or why the water map has denser channels in some areas. It is not survey-grade elevation data and should not be used to determine construction heights, property boundaries, or precise site slopes.
Why Big Lake became the county’s main reference point
The maps show Big Lake as the main settlement, but they do not by themselves explain how that happened. The Texas State Historical Association’s history of Reagan County records that the county was organized in 1903 and that Stiles was the original county seat. After the 1923 oil discovery and the rapid growth of the Big Lake area, voters moved the county seat to Big Lake in 1925. That history helps explain why the modern map has such a strong southern focus.
The same historical record connects Texon and the Big Lake oil field with the early development of petroleum production in this part of West Texas. That background adds meaning to place names on the general map, but the maps on this page do not show oil leases, mineral ownership, active well locations, or production boundaries. They should be used as geographic reference maps rather than as energy-property maps.
Choosing the most useful Reagan County map
For a broad orientation, start with the general county map. It combines the county boundary, Big Lake, smaller place labels, major roads, and nearby geographic context. The ranked city map is better when your main question is where the county’s principal settlement is located. If the subject is natural drainage, use the water map to find Slager Lake, the named creeks, and the many smaller channels. For terrain comparison, the elevation map gives the clearest view of the higher southwest and the lower eastern valleys.
Using the four maps together is especially helpful for school projects and regional comparisons. A road corridor that looks simple on the general map may cross a lower drainage area on the elevation map, while a sparsely settled part of the county may still contain a dense network of small channels. The maps are also formatted for straightforward printing, so a reader can use only the layer that fits a particular assignment instead of forcing every detail onto one crowded page.
Frequently Asked Questions
Where is Big Lake within Reagan County?
On the supplied maps, Big Lake is in the southern part of Reagan County near the meeting of U.S. 67 and State Highway 137. The ranked city map also highlights Big Lake as the only major city in its index, making it the easiest settlement to use as a reference point.
Which named water features appear on the water map?
Slager Lake is labeled in the northwest, Corral Creek and Indian Creek are named in the northeast, and Live Oak Creek appears near the southwest edge. Many smaller channels are drawn without names, so the labeled features are useful orientation points rather than a complete list of every drainage.
Can the elevation map be used for surveying or construction?
No. The map is intended for broad terrain comparison and displays an approximate countywide range of 720–902 meters. Surveying, engineering, grading, or property work requires appropriate professional measurements and source elevation data rather than this generalized reference surface.
