“However, if a system is permanently impaired it is also possible that recovery will not reach former levels,” Montagna mentioned.
Studies counsel that methods round Corpus Christi might already be “permanently impaired,” Montagna mentioned, largely attributable to a sustained lack of recent water.
Similar issues span the decrease Texas coast. The Rio Grande hasn’t flowed constantly into the Gulf of Mexico because the early 2000s. On the Colorado River, which runs by Austin, authorities have saved water releases to the coastal wetlands at a naked minimal lately. Jennifer Walker, director of the National Wildlife Foundation’s Texas Coast and Water Program, referred to as it “critical life support.”
“Water to meet environmental needs is frequently the first to be negotiated away,” Walker mentioned. “Our bays and estuaries are a hugely important part of Texas and they’re not something that would be easy to go back and fix.”
In Corpus Christi, a significant refining and export hub for Texas shale oil and fuel, metropolis authorities have imposed water use restrictions on residents, with extra to come back if reservoir ranges fall beneath 30 p.c. But the area’s largest industrial water customers function unabated, due to a purchasable exemption from drought restrictions for industrial customers—$0.25 per 1,000 gallons—handed by the town council in 2018.
That contains customers like ExxonMobil’s huge new plastics plant, which is allowed to make use of as much as 25 million gallons of water per day—1 / 4 of the regional summertime water demand.
“Industry can continue full bore through all of these drought stages and the estuary gets cut off early,” mentioned a water useful resource guide from Corpus Christi who requested anonymity to protect his enterprise relationship with the town. “I think it’s a looming disaster. They are still trying to recruit all these water-intensive industries along the coast.”
Proceeds from the exemption program have been purported to fund improvement of seawater desalination vegetation that might increase the regional water provide and meet calls for of a booming industrial buildout. The first plant was initially deliberate to start operations early final yr, but it surely stays mired in challenges and years away from breaking floor. Meanwhile, the commercial buildout continues.

Two hundred miles inland, the five-county area surrounding Austin, Texas’ high-tech capital metropolis, has grown quicker than any US metro space for 12 straight years. Its water provides haven’t.
In 2022, much less water flowed into City of Austin reservoirs than ever earlier than, metropolis workers mentioned at a public water process drive assembly on Tuesday. Last yr was solely barely higher. The largest reservoir serving Austin, Lake Travis, fell from about 80 p.c full in January 2022 to 38 p.c full in the beginning of this yr.
