Prior to election in 2013, Linda Kaye was an active citizen with the Hays Trinity Groundwater Conservation District, attending meetings and addressing groundwater issues that came before the board. In 2012 she served on the District’s rules revision committee. Linda Kaye expresses the intent to work to meet the mission of the District to “preserve, conserve, recharge and prevent waste of the aquifer”. She believes that in supporting this mission, the people in western Hays County who are dependent on the aquifer can maintain their water and property rights, their property values, and the special lifestyle that comes with living in the Hill Country.

Jeff Shaw
District 2: Term expires November 2020

Jeff Shaw is the current Board Member, representing District 2 for HTGCD, since 2018. He has dedicated thousands of hours of public service to ensure clean, safeguarded drinking water for the people of Dripping Springs, Driftwood, and Hays County. “I think long-term about water, like 20 years out,” he says. “It’s a wonder why some people don’t.” He first got involved in water policy because of his kids, going so far as to speak publicly at several DSISD board meetings. “Protecting and preserving the water we have, and keeping it clean, is for them. This is for their future.”

He has been a board member with Protect Our Water (POW) since 2016. This group of landowners came together to address water quality concerns stemming from the City of Dripping Springs proposal to dump its treated effluent into Onion Creek. He said he knew POW was on the right track when the obvious results of the dye trace study appeared within 48 hours after the dye’s release. He is directly responsible for the formation of the DS Utility Commission, whose main responsibility is finding ways to ensure clean drinking water for all future Dripping Spring’s needs. “Water doesn’t observe political lines, ” Jeff says. He talks with both Sen. Donna Campbell’s office and Bill Bunch (SOSA). His work as the District’s legislative liaison at the state capitol is supplemented by his longstanding relationships with people in all political parties, in local and state government. “I bridge the gaps,” he says.

Jeff Shaw is a native Texan, a graduate of University of Texas—Austin, and married to water artist Kara Shaw. They have two children who attend Dripping Springs schools. He coached Little League Baseball in Dripping Springs for five years, and recently helped to start Capital City Soccer Club, a top south/west Austin youth soccer club.
