Corpus Christi, a Gulf Coast city of roughly 325,000 people, is staring down a water emergency after its two main western reservoirs fell to the lowest level ever recorded. Choke Canyon Reservoir and Lake Corpus Christi now hold just 10% of their combined capacity, according to the city’s Daily Reservoir and Pass-Thru Status Report. If conditions do not improve, city projections show a formal water emergency could be declared as early as May 2026, triggering mandatory restrictions that would affect households, businesses, refineries, and farms across the Coastal Bend region.
How low the reservoirs have fallen
The two western reservoirs have long served as the backbone of Corpus Christi’s drinking water supply. Their combined storage has never dropped to 10% in the city’s recorded history. The city’s Water Supply Dashboard tracks multiple scenarios for when supply could fall short of demand. Under moderate conditions, the city’s own modeling places the threshold for a “Level 1 Water Emergency” as early as May 2026. A separate projection shared with the neighboring community of Three Rivers during intergovernmental meetings estimated the emergency arriving by November 2026, reflecting a more optimistic set of assumptions about rainfall and consumption.
Under the city’s drought contingency plan, a Level 1 Water Emergency is triggered when demand is projected to exceed total supply within 180 days. Once declared, mandatory restrictions would follow, potentially limiting outdoor watering, curbing commercial water use, and constraining industrial operations in a region whose economy depends heavily on petroleum refining, petrochemical manufacturing, military installations, and tourism.
Texas has weathered severe droughts before, most notably the statewide drought of 2011, which the state climatologist called the worst single-year drought in Texas’s recorded history. During that period, dozens of communities imposed mandatory water restrictions and some small towns came close to running out of water entirely. The current situation in Corpus Christi echoes those conditions on a regional scale, though direct comparison is limited because the 2011 drought affected a broader geographic area while the current crisis is concentrated in the western reservoir system feeding the Coastal Bend.
A temporary reprieve from Lake Texana
City officials have moved to buy time on a separate front. A planned curtailment of water deliveries from Lake Texana, a third reservoir located east of the city, was postponed after Corpus Christi secured a bed-and-banks permit allowing it to move water through natural waterways. That outcome followed a modification to the Lavaca-Navidad River Authority’s drought plan and, according to the city’s press release, a request from Governor Greg Abbott’s office to expedite temporary permits at the state level. The governor’s office has not independently confirmed that account as of late April 2026…
