Lake Lyndon B. Johnson, commonly known as Lake LBJ, is a 6,534-acre reservoir located about 45 miles northwest of Austin in the Texas Hill Country. The lake stretches for 21 miles along the Colorado River from Kingsland to Horseshoe Bay. With a maximum depth of 90 feet, Lake LBJ offers diverse paddling opportunities.

Several public boat ramps provide access for paddlers. The Wirtz Dam/Cottonwood Ramp on the south shore has a one-lane concrete ramp and parking for 20-30 vehicles. Kingsland Lions Park on the north side also has a public ramp. Sunrise Beach Village maintains three free public ramps, including one at McNair Park that is sheltered from south winds.

Lake LBJ is known for its relatively constant water level, making it reliable for paddling year-round. However, the lake can become crowded, especially during summer months. Early mornings tend to offer the calmest conditions. Water temperatures typically reach the low 80s Fahrenheit in summer.

Paddlers should be aware of potential hazards like boat traffic and submerged structures. The lake has been infested with hydrilla, an invasive aquatic plant that can entangle paddles and boats. Wildlife of interest includes various fish species like largemouth bass, white bass, catfish, and crappie.

Notable sights include multimillion-dollar mansions along the shoreline, particularly around Horseshoe Bay. The Horseshoe Bay Lighthouse, completed in 1972, is visible from the water. Paddlers can also observe the Thomas C. Ferguson Power Plant, which uses the lake for cooling water.

Lake LBJ has historical significance, having been renamed in 1965 to honor President Lyndon B. Johnson, who owned a ranch on the lake. The lake serves as one of the Highland Lakes chain on the Colorado River, playing a role in flood control and water supply for the region.
