Tonkawa Dam at Hilltop Lakes

Hilltop Lakes, TX

The Tonkawa Dam in Hilltop Lakes, TX is part of a string of spring fed lakes within the community. The existing dam had a deteriorating steel bulkhead which compromised the dams integrity. With the increased population density and this being a recreational area with boat and personal craft traffic, the dam became more critical. The repair needed to not only perform well but also be aesthetically pleasing. The engineer proposed several options with HydroTurf® being selected by the HOA due to its natural look and ease of maintenance. 

This installation was challenged by an extremely wet season. Not only did the water need to be lowered, but the installation needed to be completed quickly. In the end, HydroTurf provided little disruption to the community and an aesthetically pleasing product that easily blends with the surrounding environment. 

Overtopping of dams can lead to failure, potentially causing significant downstream damage including loss of life and property. HydroTurf is specifically designed to protect earthen embankment dams like Tonkawa Dam during overtopping. Many embankment dams have a high probability of failure due to inadequate height and insufficient spillway capacity. HydroTurf provides exceptional erosion protection for the high velocity applications of dam spillways and overtopping.

HydroTurf® is an engineered revetment solution designed to provide armoring of hydraulic structures against high velocity and shear stress. It offers the aesthetics of vegetation combined with better performance than traditional hard armor.
