Rio Vista Dam is a dam in San Marcos, Texas.
The dam was badly damaged during the flood of 1998.
Following a $2.1 million USD project, Recreation Engineering and Planning was commissioned to reconstruct the failing dam to enhance existing usage for recreational visitors and tourists alike while improving a stimulant of the local economy. REP was capable of providing a design which was tailored to the needs of the Rio Vista Dam which drastically reduced the reconstruction costs from $1.8 million to $500,000. The reconstruction efforts included removing the failing concrete side walls, grading the banks down to the water, and the addition of artificial rapids. REP completed the project in just under four months when the park reopened on May 25, 2006.
