The Old Lampasas Dam Modernization project team gave a presentation at a District 6 community meeting on January 24, 2024. View the presentation slides.
Built in 1984, the Old Lampasas Dam reduces the risk of flooding for about 30 structures and two roads downstream of the dam. In 2010, the primary outlet pipe of the dam was damaged during Tropical Storm Hermine. Due to the condition of the outlet pipe and poor construction materials, the embankment as well as the downstream slope has eroded and continues to do so when it rains. Numerous holes have formed on the upstream slope of the dam. The eroding slopes are unsafe.
Project Overview
The purpose of this project is to improve and modernize the dam to meet city and Texas Commission on Environmental Quality dam safety regulations and to improve water quality in Bull Creek. The project includes:
Replacing the damaged primary outlet
Improving the dam spillway
Modifying the shape and elevation of the embankment

Timeframe and Cost
Our capital improvement projects take many years from start to finish. The process typically includes the following phases:
Preliminary Engineering – when a solution is identified and costs are estimated.
Design – when the details are worked out and construction plans drawn up.
Bidding and Permitting – when a contractor is hired and all permits are acquired.
Construction – when the project is built.
This project is currently in the design phase. Construction is anticipated to begin in the fall of 2024.
The construction cost is estimated at $12.8 million.
