Reservoir owners and operators in Southeast Texas are all familiar with the concept of non-native, or invasive, aquatic vegetation growing in their waters and the various management techniques available to help control their existence. Through close partnerships with local, state, and federal organizations, especially the Texas Parks and Wildlife Department (TPWD), the Lake Conroe Division of the San Jacinto River Authority (SJRA) manages invasive aquatic plants, zebra mussels, and other invasive species on the Lake Conroe Reservoir. In addition, the Division has developed a program to establish and maintain native vegetation across the reservoir and sustain a suitable fisheries habitat.
Lake Conroe invasive species efforts have historically targeted three primary species of plants: Hydrilla, Water Hyacinth, and Giant Salvinia. Hydrilla is a submerged and rooted plant that generally grows in shallow water. Water Hyacinth is a floating invasive species with large purple flowers that bloom in the summer. Giant Salvinia also floats freely on the surface of the water and resembles a fern. Each one of these plants presents its own unique challenges, but all three can cause serious environmental, as well as economic havoc on an aquatic environment. Countless hours have been spent to keep these three plants under control on Lake Conroe.
