Mission routes, Republic-era politics, pine forests, poultry farms, and reservoir coves occupy the same compact East Texas county. A San Augustine County Texas map places the historic county seat north of center, Broaddus near the southern recreation corridor, and the Attoyac River along the western edge. The pattern is more useful than a simple town list because most residents and economic activity are spread among forest roads, farms, small communities, and lake access points.
The Census Bureau estimated 7,722 residents on July 1, 2025, 2.5 percent below the 2020 estimate base of 7,921. San Augustine remains the principal government and service center, while timber, agriculture, public employment, and Sam Rayburn tourism support rural parts of the county.

Ayish Bayou Connected Native, Spanish, and Anglo Settlement
The Ais, part of the Hasinai Caddo world, occupied this area long before European settlement. Spanish authorities established Mission Dolores de los Ais near Ayish Bayou in the early eighteenth century and used the Old San Antonio Road to reinforce their presence in East Texas. Although the mission did not become a permanent colonial town, its location marked a long-used route between Indigenous settlements, Louisiana trade, and Spanish Texas.
Anglo-American settlers later called the area the Ayish Bayou District. San Augustine developed as a commercial and political center during the Mexican period and became the county seat after Texas independence. County offices were elected in 1837, placing the community among the early administrative centers of the Republic of Texas.
Sam Rayburn Changed the Southern Landscape
Sam Rayburn Reservoir is a 114,500-acre impoundment of the Angelina River extending through several East Texas counties, including San Augustine County. Its coves and tributary arms reach the county’s southern side, where Broaddus provides a practical gateway for marinas, boat ramps, fishing, and lakeside lodging. Water levels vary, so shoreline details may change from one season or drought cycle to another.
The reservoir also inundated the lower reaches of some older streams, including parts of Sandy Creek. Turkey Creek flows through forested terrain toward Ayish Bayou, while the Attoyac River forms much of the western boundary. These waterways explain why the southern and western edges appear less regular than straight survey lines.
Pine Forests Support Timber, Wildlife, and Poultry
San Augustine County lies in the East Texas Timberlands, with pine stands interspersed with oak and other hardwoods. Lumbering and sawmill activity have long been important, and a substantial portion of farm and ranch acreage remains wooded. The Angelina National Forest adds public forest land and wildlife habitat in the southern part of the county.
Poultry production became a major agricultural income source during the twentieth century, alongside cattle, hay, vegetables, and other crops. Modern employment also includes health care, education, retail, government, logging, transportation, and visitor services. The result is a rural economy in which forest products and lake recreation operate beside agriculture rather than replacing it.
Highways Meet at the County Seat
San Augustine sits at the junction of U.S. Highway 96 and State Highways 21 and 147. U.S. 96 connects north toward Shelby County and south toward Jasper County, while State Highway 21 follows an older east–west route toward Nacogdoches and Sabine County. State Highway 147 runs south toward Broaddus and Sam Rayburn Reservoir.
Smaller places such as Bland Lake, Denning, Macune, Chinquapin, and Grapevine identify rural sections that otherwise contain few incorporated towns. Those labels help distinguish the north, east, and central parts of the map. They should not be interpreted as continuous urban areas, because settlement is dispersed through forest and farm country.

Color Map
The color map separates San Augustine County from Nacogdoches, Shelby, Sabine, Jasper, and Angelina counties. Broaddus can be compared northward with San Augustine, while Denning and Bland Lake provide eastern and northeastern references. Sam Rayburn Reservoir and the Attoyac River frame the southern and western sides of a county dominated by timberland.
Black-and-White Map
This version removes color fills but keeps the county outline, neighboring boundaries, and selected place names. Macune and San Augustine remain easy to compare with the reservoir corridor near Broaddus. It is designed for reports, worksheets, and low-ink printing.
Outline Map
The outline base removes both labels and colored areas, leaving San Augustine County and surrounding county lines. Users can add San Augustine and Bland Lake, trace the Attoyac River, or mark Sam Rayburn Reservoir and State Highway 147. The open layout also supports custom forestry, settlement-history, or watershed projects.

Frequently Asked Questions
Why is Ayish Bayou important to local history?
The Ais lived in the area, Spanish missions were established nearby, and later settlements used the same corridor. The bayou therefore links Indigenous, Spanish, Mexican, and Republic-era history.
Is Broaddus the main lake-access community?
Broaddus is the principal incorporated community near the county’s southern reservoir corridor. Individual marinas, ramps, and recreation areas are spread around different coves and roads.
Does the outline file show national-forest boundaries?
No. The outline version is limited to the county and surrounding boundary framework. Detailed Angelina National Forest ownership and recreation units require a separate federal land map.
