President – Zach Holland
Bluebonnet Groundwater Conservation District

Zach Holland is the General Manager for the Bluebonnet Groundwater Conservation District, serving Austin, Grimes, Walker, & Waller Counties. Zach is originally from Mertzon, Texas and grew up with firsthand knowledge of groundwater management from his Dad, Scott, who serves Irion County Water Conservation District and Sterling County Underground Water Conservation District. Zach’s love of groundwater led him to Texas A&M University, where he earned a Bachelor of Science degree in Animal Science (2008) and then a Masters of Water Management & Hydrological Sciences (2010). His graduate research focused on a Carrizo-Wilcox Study ordered by Senator Ogden and highlighted the benefits and good works of groundwater conservation districts. Through that project, Zach was able to reach out to many districts and gain a greater understanding of groundwater management of a completely different aquifer and area of the state than his upbringing. Zach has served the Bluebonnet GCD in varying capacities since October 2009.
