Jordan Austin

Past President

TAPMS member since 2010

Conroe, TX

Lake Conroe Operations Manager for the San Jacinto River Authority

I earned my Bachelor’s Degree in Agriculture Development from Texas A&M University in College Station, TX, Class of 2008.  In 2011, I decided to go back to school and I’m currently working on my Master’s Degree in Water Management from Texas A&M and should be done by December 2015.  I started my career with the San Jacinto River Authority in 2010, and I am currently the Lake Conroe Operations Manager.  We handle a numerous amount of different tasks here at the Lake, including aquatic plant management.  I am involved in the management and strategic planning of our treatment techniques of invasive plant species, but also the re-establishment of our native plants.  Lake Conroe has a history of treating Giant Salvinia, Water Hyacinth, and Hydrilla (among other species).  In the era of 2006-2008, Lake Conroe experienced a large volume of these three plant species across the entire reservoir, which called for a vast amount of chemical and biological controls in order to overcome the spreading of these invasive plants.  We continue to treat the reservoir in order to keep this from happening again.
