A century after its construction, the Rio Vista Dam on the San Marcos River was cracked and tired, in need of replacement. Following the Colorado model, councillors in San Marcos, Texas sought to replace the dam with a whitewater park. There’s a strong paddling tradition in Texas, and the San Marcos was already popular for downriver float trips. Completed in 2006, Rio Vista Park made the San Marcos even better for boating. What’s more, the river’s lush overhanging trees, aquamarine water and bleached shoreline rocks became the town’s focal point.
With 10 feet of drop at the Rio Vista Dam alone, designer Lacy had plenty of hydraulic potential to work with. The gradient was divided into three features, including a lead-in slide, a middle-hole feature, and a ledge drop at the bottom of the run. Each feature comes in at different flow rates, which range from less than 150 cfs to more than 300 cfs. The spring-fed San Marcos holds water throughout the paddling season.
Rio Vista is notoriously busy in the summer months, when tubers pack the river to escape the heat. But artificial lighting allows paddlers to surf long into the night, after the crowds have dissipated.
