TRA names Southern Region assistant manager, Lake Livingston Project manager

Following the recent retirement of longtime Southern Region Assistant Manager Robert Stevens, the Trinity River Authority of Texas has named William Holder, former manager of TRA’s Lake Livingston Project, as his successor. Mark Waters, former LLP assistant manager, has advanced to project manager at Lake Livingston.

During his 40-year career with TRA, Stevens held a number of management and supervisory positions in both the Southern and Northern regions of the Trinity River basin. He was known for maintaining outstanding working relationships with TRA’s customer cities and for his exceptional attention to detail.

Holder joins the Southern Region management team after serving for 32 years in positions of increasing responsibility at LLP. He most recently served as LLP project manager for 20 years.

As assistant regional manager, Holder will develop and manage operating project budgets and serve as liaison for customers of the Southern Region’s three regional water supply systems, as well as LLP and Livingston Recreation Facilities. He will also manage project expansions and capital improvements, and will represent TRA in its LLP hydropower partnership with the East Texas Electric Cooperative. 

Holder earned a bachelor’s degree in chemistry from Sam Houston State University, a professional sanitarian license from the Texas Department of State Health Services and a Class A wastewater license from the Texas Commission on Environmental Quality. He has trained extensively with the Federal Emergency Management Agency and the Department of Homeland Security.

Waters takes the helm at TRA’s Lake Livingston Project after serving as its assistant manager for nearly 20 years. As project manager, his main duties will include preparing and managing an operating budget in excess of $4 million, managing employees, directing reservoir operations, managing flood events, and managing repair and rehabilitation projects.

Waters joined TRA in 1989 as a field inspector and advanced to LLP assistant project manager within four years. He earned a bachelor’s degree in wildlife biology from Texas Tech University and a professional sanitarian license from the Texas Department of State Health Services. In addition, he has completed training through the Federal Emergency Management Agency and the Texas Recreation and Parks Society.
