The Lampasas River is a scenic waterway in central Texas, originating in western Mills County and flowing southeast for approximately 75 miles before joining the Leon River to form the Little River, a tributary of the Brazos. The river passes through the Texas Hill Country, draining portions of Mills, Lampasas, Burnet, and Bell counties. Paddling opportunities on the Lampasas vary greatly depending on rainfall and releases from Stillhouse Hollow Dam. The upper reaches above Stillhouse Hollow Lake offer a more natural, undeveloped paddling experience when water levels permit. Below the dam, recreational paddling is possible during controlled releases, with several access points along the 17.5-mile stretch to the confluence with the Leon River.

The difficulty of paddling the Lampasas ranges from Class I flatwater to Class II+ rapids, depending on the section and water levels. The upper sections require more skill to navigate potential hazards like log jams and strainers, especially after heavy rains. Below Stillhouse Hollow Dam, the river is generally more forgiving but can become swift during high releases. Spring and fall are typically the best seasons for paddling, when rainfall and releases are more consistent. Summer often brings low water conditions, while winter can be unpredictable. Paddlers should always check current flow rates and release schedules before planning a trip.

The river corridor supports diverse wildlife, including white-tailed deer, wild turkeys, and various fish species. The surrounding landscape features limestone bluffs, pecan bottoms, and oak-juniper woodlands typical of the Texas Hill Country. Notable landmarks include the historic town of Lampasas, known for its mineral springs, and Stillhouse Hollow Lake, a popular recreational area. Access points are available at several road crossings, with key put-ins near Lampasas, Youngsport, and below Stillhouse Hollow Dam.

The Lampasas River played a role in early Texas settlement and continues to be an important water source for the region. Today, it offers a mix of scenic beauty and recreational opportunities for paddlers, anglers, and nature enthusiasts. Safety considerations include checking water levels, being aware of potential strainers and log jams, and respecting private property along the banks. Some sections may require a Texas Parks and Wildlife Department public river access lease agreement. While most paddling trips on the Lampasas are day excursions, multi-day trips are possible on the upper reaches during favorable conditions, though camping options are limited and should be carefully planned.
