Corpus Christi: a record port on an eight percent reservoir

In the second quarter of this year, 55.8 million tons of cargo moved through the Corpus Christi Ship Channel. It was the best quarter in the port's 99 year history, and it broke the record set the quarter before. The first half of 2026 came in 7.7 percent ahead of the first half of 2025, with liquefied natural gas up 36 percent and agricultural exports up from 189,000 tons to 2.1 million.

Twelve miles up the Nueces River, Lake Corpus Christi and Choke Canyon Reservoir, the two lakes that hold three quarters of the city's water supply, sat at a combined 8 percent of capacity through the spring. Choke Canyon was at 47 percent in October 2021. The city has banned lawn watering since 2023, cancelled its billion dollar desalination plant last September, had its credit outlook cut to negative by Fitch in April, and has been told by its own engineers that a Level 1 water emergency, the first ever declared by an American city of this size, is a matter of when.

Both of those paragraphs are true of the same place in the same year. That is Corpus Christi, and anyone underwriting Nueces County has to hold both at once.

The port

Start with what it is, because the scale is easy to underrate from Houston. The Port of Corpus Christi is the third largest port in the United States by tonnage. It is the largest crude oil export gateway in the country and the third largest in the world, behind only Russia and Saudi Arabia, moving more than 2.4 million barrels a day to foreign buyers. It is the second largest LNG export gateway in the United States. Trade through it was worth about $89 billion in 2024. In a decade it went from about 85 million tons a year to more than 200 million, and nearly all of that growth is one thing: Congress lifted the crude export ban in December 2015, the Permian pipelines converged here rather than at Houston, and the port built the channel to receive them.

That channel is the piece of infrastructure that changed the trajectory. The Channel Improvement Project, conceived more than thirty years ago and finished in June 2025, deepened the ship channel from 47 feet to 54 and widened it from 400 feet to 530, with barge shelves on either side. Cost was about $625 million, split between the port, Congress, and the Army Corps. What it buys is very large crude carriers loading at the dock instead of lightering offshore, and two way traffic where there used to be one. The port's own estimate is that exporters save more than $200 million a year in transportation cost. The new Harbor Bridge, which replaced a 1959 span with a cable stayed bridge tall enough to clear the vessels the deeper channel invites, went into service alongside it.

The 2026 numbers are the first full year with both in place, and the mix is what to read. Crude, the dominant commodity, was up only 1.3 percent in the first half. The growth came from everything else: LNG up 36 percent to 11.5 million tons, refined products up 9 percent, natural gas liquids up 18 percent, other bulk liquids up 12 percent, and agriculture up more than tenfold. The port CEO has said publicly that the next thing he is looking at is container service, which Corpus Christi has never handled, and that the constraint on crude is now pipeline capacity from West Texas rather than dock capacity here. Two of the three main lines are expandable.

Now put the Middle East next to it. The Strait of Hormuz has been running at a fraction of normal flow since the Iran conflict began. Saudi Arabia shut its East West pipeline after attacks this month and has cut crude shipments to Europe. Every barrel that does not leave the Gulf is a barrel Europe and Asia buy from somewhere else, and the somewhere else with a 54 foot channel, VLCC docks, and six million barrels a day of Permian supply behind it is this one. The Q2 record was set before most of that happened. Q3 will not be smaller.

What is across the bay

Here is the county lens, and it matters more in Corpus than anywhere else we have written about.

Nueces County holds the city, the port headquarters, the three refineries on the Inner Harbor run by Valero, Citgo, and Flint Hills, the Naval Air Station, the universities, and, since January, the Tesla lithium refinery in Robstown. What it does not hold is most of the new industrial buildout. Cheniere's Corpus Christi Liquefaction, the LNG plant whose Stage 3 expansion is the reason LNG tonnage is up 36 percent, sits in San Patricio County across the bay. So does the ExxonMobil and SABIC ethylene cracker at Gregory, the Steel Dynamics mill at Sinton, and the Enbridge crude terminal at Ingleside, which loads more crude than any single terminal in the country. The port's growth story is largely a San Patricio story that clears customs through a Nueces County channel.

Nueces County has no public company headquarters of any size. Whataburger was founded here in 1950 and moved to San Antonio in 2009. The refineries answer to San Antonio, Houston, and Wichita. Cheniere answers to Houston, Tesla to Austin, Enbridge to Calgary. This is a county where other people's capital works, and where the profits on that capital are booked somewhere else. What stays local is payroll, property tax, and water demand.

The Tesla plant is the exception worth watching. It broke ground in Robstown in May 2023, went operational in January, and reached full integrated capacity in February: the first facility in North America to take hard rock spodumene concentrate, most of it Australian and landed through the port, and convert it to battery grade lithium hydroxide on one site. It ships to Giga Texas by rail. It employs about 400 people. It also needs water in a county that has none to spare, and the water contract it signed with the South Texas Water Authority was the subject of a public fight before the plant opened.

Water

This is the headwind, and it is not a footnote.

Corpus Christi Water serves about 500,000 people across seven counties and one of the largest industrial corridors in the country. Its supply comes from three places: the two Nueces basin reservoirs, and a pipeline system that brings water from Lake Texana and the Colorado River. The reservoirs are the base. They have been in decline since late 2021, when Choke Canyon was at 47 percent, and they reached 7.8 percent combined on May 1 of this year. Rain in May and June moved Lake Corpus Christi up meaningfully; Choke Canyon, the larger of the two and the one that matters, barely moved. Combined storage sits around 8.5 percent, well below the 20 percent that triggered Stage 3 restrictions in the first place. The pipeline system, which was built as a supplement, now supplies about 73 percent of the city's water.

The city's engineers projected in the spring that the system would hit the 180 day supply threshold that triggers a Level 1 Water Emergency by this September. The rains pushed that projection out, to 2027 at the earliest by most accounts. A Level 1 emergency means mandatory cuts for every user, industrial customers included, enforced by surcharges the city is not sure it can legally impose on its largest accounts, ten of which are permanently exempt under their contracts. Nobody has done this before. The city manager told council there is no manual.

The solution everyone agreed on was seawater desalination. The city spent a decade courting industrial customers on the promise of an Inner Harbor plant that would deliver 30 million gallons a day by 2028, most of it for industry. The cost estimate went from $757 million to $1.3 billion. Last September the council killed it. In June, after a fifteen hour meeting, it voted 7 to 2 to delay a decision on reviving it. Moody's downgraded the city in December. Fitch cut its outlook to negative in April. Both cited drought supply risk and the unfunded cost of doing something about it. The governor criticized the city's handling publicly and ordered state agencies to suspend normal procedures to buy time.

What is actually being built: Nueces River groundwater wells supplying about 12 million gallons a day, at pumping rates the aquifer cannot sustain for years. A reclaimed water project delivering its first million gallons a day next month. And a privately owned desalination plant at Corpus Christi Polymers, permitted and nearly complete, from which the city is now negotiating to buy water. The city has approved about $1 billion in financing toward 76 million gallons a day of new capacity across all of it, but none of it is in service yet, and the former chief operating officer of Corpus Christi Water, who resigned when the desal plant died, put it plainly: curtailment ends when the weather changes or a large new supply arrives, and there is no large new supply lined up.

For a real estate reader the translation is direct. Every industrial customer on the corridor signed a water contract assuming the desal plant. Every one of them is now a party to a curtailment plan that does not exist yet. And the city's cost of borrowing to fix it just went up twice.

Real estate

Corpus Christi is a buyer's market and has been for a year. The city median sale price was about $295,000 in April, flat to slightly down, with homes sitting 73 days against 61 a year earlier and more than eight months of inventory. About 37 percent of active listings have cut price. Two thirds of sales are closing below list. Zillow's home value index for the city is about $219,000, down 1.4 percent on the year. The metro average, which includes Aransas and San Patricio, was about $342,000 in May 2025, down from $378,000 the year before.

Two structural facts underneath that. First, this is a slow growth labor market by Texas standards. Between 2012 and 2023 the metro's labor force grew less than one percent while the state's grew 19 percent, and unemployment has run roughly a point above the state for years. The $28 billion in industrial projects announced over the last five years did not translate into population the way the same money would in Houston, because the plants are capital intensive and the construction labor commutes. Second, prices ran anyway: the city median rose 96 percent from 2012 to 2023 against 75 percent nationally. A flat labor force and a near doubling in price is a market that got ahead of its own economy, and the eight months of inventory is that gap closing.

Homeownership in the county is about 60 percent and median household income about $54,000, which puts a median priced home out of reach for a median family at current rates. Rents around $1,400 are cheap by Texas standards. The submarkets that hold value are the ones the water problem touches least and the schools touch most: the Southside along Yorktown and Saratoga inside London ISD, the Island across the causeway, Flour Bluff, and Calallen to the northwest. The Northside and the corridor along the refineries do not.

Schools and institutions

Texas A&M University Corpus Christi, the Island University, sits on its own island in Corpus Christi Bay and is the largest degree granting institution in the county, with programs in marine science, engineering, and nursing that feed the port and the hospitals directly. Del Mar College is the community college and the workforce pipeline for the plants; its welding and process technology programs are what the industrial employers actually hire from. Together they awarded about 4,800 degrees in 2024, roughly nine tenths of the county's total.

The Navy is the institution people forget. Naval Air Station Corpus Christi trains Navy, Marine, and Coast Guard pilots and hosts the Corpus Christi Army Depot, the largest helicopter repair facility in the world and one of the largest civilian employers in South Texas. That payroll does not move with oil prices, which is the only thing in the county that can say so.

At the district level, London ISD south of the city is the one buyers pay for, a small A rated district that has become the Southside's price anchor the way Highland Park is Dallas's. Flour Bluff and Calallen are the next tier. Port Aransas ISD is tiny and strong. Corpus Christi ISD is large, mixed, and carries the weight of the city's average GreatSchools rating of four out of ten. As in Dallas, the price gap between the A rated districts and the rest is the clearest map of where value sits in the county.

What would change the picture

Corpus Christi is the purest version of the Texas thesis in this series: the state as the world's marginal energy supplier, with the world's marginal energy demand routed through one 54 foot channel. It is also the clearest case of a place whose growth is capped by something it cannot ship in. The port can move 55 million tons a quarter. It cannot move a reservoir.

Before committing capital we would want:

• A large water supply under contract. The Corpus Christi Polymers desal purchase, a revived Inner Harbor plant, or an executed regional pipeline expansion. Not planned. Signed. Everything else in this county prices off that document.
• Choke Canyon above 20 percent, which is the Stage 3 threshold, or a Level 1 emergency declared and survived. Either resolves the question. Living between them does not.
• Fitch and Moody's back to stable. The city's borrowing cost is the cost of every solution, and two agencies just said it is going the wrong way.
• Container service announced, or a pipeline expansion financed. The port's next leg of growth is not crude, and either announcement would say the diversification is real rather than aspirational.
• Inventory below six months in the Southside and on the Island. That is where the county's residential value lives, and eight months means the correction is still running.

The port is the best story on the Texas coast. The water is the most serious infrastructure failure in the state. They share a city council, a tax base, and an aquifer. We will keep reading this one closely, because the day the water is solved is the day the port's numbers start meaning what they appear to mean.
