The Double Mountain Fork Brazos River is a significant tributary of the Brazos River system in West Texas. Originating on the Llano Estacado, this ephemeral, sandy-braided stream flows approximately 170 miles eastward before joining the Salt Fork to form the main stem of the Brazos River near the town of Old Glory.

Paddlers can enjoy several notable sections along this river, with the most popular stretch being the 64-mile run from Clairemont to Old Glory. This section offers Class II-III rapids, making it suitable for intermediate paddlers seeking a multi-day adventure through the scenic landscapes of Kent and Stonewall counties. Another noteworthy segment is the 22-mile Slaton to SH 207 stretch, which provides Class II whitewater and is part of the North Fork of the Double Mountain Fork. The river's difficulty ranges from Class I to III, with most sections falling in the II-III range. Paddlers should have intermediate skills and be comfortable with moderate rapids and longer trips.

Due to its ephemeral nature, the best paddling times are typically in spring or after significant rainfall events when water levels are sufficient. The Double Mountain Fork flows through a semi-arid region characterized by rugged terrain and diverse wildlife. Paddlers may encounter native species such as roadrunners, coyotes, and various bird species adapted to the West Texas environment. Key landmarks include the river's namesake, Double Mountain, a distinctive geological feature in Stonewall County.

Upstream near Lubbock, paddlers should note the presence of two man-made lakes: Buffalo Springs Lake and Lake Ransom Canyon, which, while not part of the paddling route, are interesting features of the river system. Access points are limited due to the remote nature of the region. Primary put-in and take-out locations include Clairemont, Old Glory, and Slaton, with SH 207 serving as a notable landmark for river access.

The Double Mountain Fork holds historical significance as part of the larger Brazos River system, which has played a crucial role in the development of Texas. The river's name and character reflect the rugged landscape of the region.

Safety considerations include the river's flashy nature and potential for rapid water level changes. Paddlers should check water conditions before embarking and be prepared for self-rescue in remote areas. Multi-day trips are possible, particularly on the Clairemont to Old Glory section, but require careful planning due to limited access points and services along the route.

For those seeking a true Texas river adventure, the Double Mountain Fork Brazos River offers a challenging and rewarding experience through some of the state's most iconic landscapes.
