Corpus Christi is facing water bankruptcy. Without significant rainfall (30 inches this summer), Corpus Christi is headed for a “water emergency” by fall and will reach a point next year where city supply can no longer meet demand. Corpus Christi with reach "Day Zero” the specific day a city's municipal water supply is projected to run out . On this day, authorities must shut off taps to homes and businesses, leaving residents to collect a limited daily water ration. Though, Corpus Christi actually has no operational ability to do this.
Residents have been living under Stage 3 water restrictions
since December 2024. These restrictions ban lawn watering and limit most
outdoor water use to specific days and hours. City officials have warned that a
formal water emergency could be declared later this year. This emergency stage
would require mandatory reductions not only for residents, but also for major
industrial and commercial water users.

A NASA analysis released in January showed satellite images comparing October 2021 to October 2025 highlighting the shrinkage in both Choke Canyon Reservoir and Lake Corpus Christi, the two primary water sources for more than half a million residents across the Coastal Bend.

According to NASA, Choke Canyon Reservoir dropped from 47 % capacity in 2021 to just 11% in 2025. Lake Corpus Christi fell from 87% to 14% over the same period. Combined storage fell to 10 % as of January 20, 2026. As of March 13th, 2026, the combined storage levels of Choke Canyon Reservoir and Lake Corpus Christi are at 8.7% according to the City of Corpus Christi water dashboard.
City officials also noted that portions of that remaining
water may not be fully usable due to sediment accumulation and arsenic that can
damage filtration and treatment systems. A regional drought that has slowly
intensified over several years has contributed to the problem, but according to
an article published in Inside Climate News, two large industrial users in
recent years have drained the reservoirs.
Exxon’s plastic plant started operations in 2022 and consumes
25 million gallons of water per day. This water use was approved despite the region’s
water plan projecting that the region would exceed water supply. Corpus Christi then approved another 6 million
gallons of water a day to Steel Dynamics, which then built a steel mill in
the area and came online a few years ago.
There really was not enough water, but Corpus Christi had
been discussing desalination for years. In 2016 many local politicians and
staff traveled to Israel where they toured the world’s largest seawater
desalination plant and met with Israeli officials to discuss desalination.
Later that year, an industry group hosted an event in
Corpus Christi. They proposed desalination plant they would produce 10 million
gallons per day, cost $140 million and take two years to build, the
presentation said. It would begin supplying water by the start of 2023. The Corpus
Christi City Council was on board, but only preliminary proposals were produced.
By 2020 the size of the proposed plant had doubled. In the beginning of
2024, Corpus Christi City Council produced a new cost estimate the proposed
desalination plant of about $550 million to produce 30 million gallons of
freshwater per day. A subsequent cost estimate put the project at nearly
$760 million. Then in July 2025 the cost estimate was raised to $1.2 billion and
still no plans or drawings were generated. Two months later, Corpus
Christi City Council voted to cancel the project . For more details read the
excellent Inside Climate New article and the City of Corpus Christi water news.
Meanwhile, the City of Corpus Christi under threat from
Governor Abbott to take over their water operations has rolled out a series of
long-term measures, including the development of wells, the purchase of
groundwater rights, and evaluations of future desalination capacity. None of
which seem likely to meet demand in time.
Following the Inside Climate News article publication,
Corpus Christi officials denied immediate "Day Zero" scenarios. The situation, driven by a 4 year-long drought
and high industrial demand, has prompted new modeling efforts that are
suggesting that indeed critical, low-level water conditions could emerge this
year. There simply is not enough water.
Corpus Christi is bracing itself for a level
one water emergency where the city’s plans call for an immediate 25%
curtailment of water consumption. The city has not yet determined how they
would implement it. Also, Climate News reported that the region’s largest
industrial users, which collectively consume most of the the region’s water,
remain exempt from emergency curtailment. The city denies that the industrial
users are exempt, but that remains to be clarified. These multi-billion-dollar
refineries, petrochemical plants and liquified natural gas facilities are designed
to run at a steady rate and can’t simply throttle down production in accordance
with water availability. Water is consumed primarily in cooling towers to
prevent excessive heating and explosions. Not really something you want to
throttle back.
