About this map

Dorchester and Sperry sit at the center of this North Texas landscape, where the headwaters of the East Fork Trinity River begin their southward journey. The terrain is defined by a dendritic network of streams including Choctaw Creek and its South Branch, which drain towards the Red River basin while Buck Creek and Little Elm Creek flow toward the Trinity. This drainage divide is marked by local water management infrastructure such as the Soil Conservation Service Site 18 Dam and Soil Conservation Service Site 10a Dam.

A network of farm-to-market roads and historic thoroughfares, including the Old Preston Rd and Old Gunter Hwy, connect these rural communities. The layout of rural routes like Morman Grove Rd and Colonel Hall Rd reflects the agricultural character of Grayson County at the beginning of the 21st century, showing the transition between the expanding outskirts of Sherman to the north and the persistent open ranchland and farms to the south.
