Small towns in South Texas are urgently seeking alternative drinking water sources as persistent droughts threaten to deplete their main supply.
Mattis City typically relies on Lake Corpus Christi for its drinking water; however, the intensifying drought is projected to drop levels too low for safe extraction, according to Cedric Davis from the city.
“It’s not about completely running out of water,” said Davis. “It’s just challenging to access clean water from the lake, as the extraction process brings up sediment.”
That sediment can harm urban filtration and treatment systems, he noted. According to 2020 data from the US Census Bureau, Mattis has a population of approximately 4,300.
The situation in Texas underscores the escalating challenges faced in drought-affected areas nationwide, as climate change alters rainfall patterns and reduces the availability of safe drinking water.
In 2023, New Orleans experienced a drinking water emergency when saltwater infiltrated upstream due to unusually low levels in the drought-impacted Mississippi River.
Last year, ongoing drought and years of low precipitation led to alarmingly low reservoir levels in Mexico City, resulting in significant water shortages for North America’s most populous urban areas.
South Texas has a long history of dry spells, with much of the region categorized as facing “moderate” or “severe” drought conditions. The US Drought Monitor publishes updated color-coded maps weekly to illustrate the extent and severity of droughts nationwide.
Extreme dryness has resulted in falling water levels in Lake Corpus Christi.
“There isn’t enough rain to restore the lakes and reservoirs in South Texas,” said Davis, indicating that several municipal and small community areas will need to seek emergency solutions.
Davis mentioned that projections indicate lake levels may become critically low by late December. Thus, the city is initiating the drilling of two emergency wells to ensure a continued supply of drinking water.
Although the project is still in the planning stages, Davis expressed hope that the permitting process and lease agreement with the Texas Parks and Wildlife division could be expedited. If all goes well, excavation may commence by the end of October.
“If everything goes as planned and we can install the wells by late December, we should be fine,” stated Davis.
Nonetheless, city officials are exploring additional contingency options, including potentially expensive desalination plants and wastewater treatment and reuse systems.
“We haven’t ruled anything out,” Davis concluded.
