A big thank you to all those who participated in the 2018 visits!
Water level tracking is particularly important in Edwards and Trinity wells, because water levels fluctuate substantially during drought and wet periods. When home owners know the depth of their pump, a water level measurement can show how much water is above the level of the pump.
In collaboration with Travis County and to help residents better understand groundwater trends, District staff completed five weeks of neighborhood site visits focused in five different areas throughout southwestern Travis County. During the free site visits, staff took a water level measurement (if possible), and measured basic water quality. About 45 well owners participated and over 50 wells were visited total by staff.
Data collected during the visits is currently being compiled and will be shared with participating well owners. These site visits will aid in better understanding of local hydrology and geology.
The five areas included:
- Oct. 30-31: Hamilton Pool, Pedernales Area
- Nov. 6-7: Spicewood, Briarcliff Area
- Nov. 13-14: Lakeway, The Hills, Hudson Bend Area
- Nov. 20-21: Bee Cave Area
- Nov. 27-28: Westlake, Lost Creek, Oak Hill Area
