Comments on Charlotte Water's Interbasin Transfer Request

Sustainable Solutions: Water Conservation, Mitigation, & Assessing Impacts on Endangered Species

Catawba Riverkeeper works to preserve, protect, and restore the Catawba-Wateree watershed for all. We are currently working with over 6,000 active members who are concerned about the proposed expansion of Charlotte Water’s Interbasin Transfer (IBT) and the similar future requests from municipalities across the basin. 


Twenty-three years ago, the first Catawba Riverkeeper, Donna Lisenby, spoke in a similar forum as Charlotte requested to expand its legacy IBT of 16.9 to the current 33 million gallons per day (MGD). She also spoke out during the 2006 IBT request of Concord and Kannapolis. In 2010, our organization advocated during the South Carolina vs. North Carolina Supreme Court case. Eleven years ago, we commented on the proposed amendment to Charlotte Water’s permit. It is my lofty goal to be the last Catawba Riverkeeper who must address this challenge. 


Our position is this: it is irresponsible and not sustainable to simply allocate more Catawba River water to other basins. While we have an abundance most years, it is a finite resource in a rapidly developing area that must not be over allocated. We are advocating that Charlotte Water take this opportunity to lead the region into the next phase of water conservation and mitigation. We need a new system that better captures the value of our surface waters for current and future generations. While we are still meeting with experts and stakeholders to develop our full recommendations for the August 30th deadline, there are many ways to decrease the demand for transfers and increase the available supply. 


The alternatives analysis should include requiring and incentivizing water conservation, such as high efficiency fixtures, greywater systems, and non-potable reuse. A condition of Charlotte Water’s 2002 IBT was the formation of a stakeholder group that created a Post Construction Stormwater Ordinance. A similar group could be created to develop effective water conservation measures. 


While it might not be feasible (or desirable) to create a new reservoir on the Rocky River, Charlotte Water could offset their use through mitigation. One solution is to establish a fund that all future IBT’s would pay into. This could be used for funding source water protection, groundwater recharge, loss prevention, restoration, etc. Such a fund already exists in the Catawba Wateree Management Group. 


Finally, we recommend reassessing the impacts to the federally endangered Carolina Heelsplitter. Many of the recommendations from federal and state biologists were not adopted during the last permit and should be reconsidered with the latest decade of data. 


As demand for water continues to grow in the Charlotte region, we are looking forward to being part of a sustainable solution.

On the evening of May 26th, 2026, Catawba Riverkeeper Brandon Jones attended the Charlotte City Council Public Meeting. At this meeting, he shared our organization's comments on the proposed 150-day data center moratorium. These comments can be read below. "The Catawba Riverkeeper Foundation is a member-funded environmental nonprofit that educates, advocates, and protects the Catawba-Wateree River and all its tributaries. Our organization represents over 8,000 active members and nearly 3 million citizens who rely on the watershed for drinking water, recreation, and electricity. We are concerned that the growth of local data centers may overallocate our limited resources and decrease our ability to respond to drought. We appreciate the opportunity to comment on the proposed 150-day moratorium and strongly support the staff's recommendation to adopt it. Additionally, if adopted, we recommend that the study consider a tiered approach, transparency, and net water consumption. For our water resources, the most important data center metric is net water use. A 400 MW facility—like the one now under construction on Moores Chapel Road—may actually evaporate more water indirectly than directly for cooling. The nearby Catawba Nuclear Station uses approximately 30 MGD to produce 2,300 MW or 5.2 MGD from Lake Wylie per 400 MW. However, without transparency and reporting, it is difficult to know the current impact of these data centers and almost impossible to accurately forecast the industry's future. The most accurate forecast of our region's water resources is the Catawba Wateree Water Management Group’s 2026 Integrated Water Resources Plan. Unfortunately, this plan explicitly does not include increases in water use from data centers due to limited reliable information. It is absolutely critical that our community has accurate information. We need full transparency on the planned electrical and water use of large data centers. A ban of nondisclosure agreements between elected officials and developers could help alleviate suspicion and allow communities to make informed decisions about tradeoffs. The potential direct and indirect impact s of a project should be modeled by the CWWMG to determine its actual impacts. Those impacts could be mitigated by funding water conservation projects, as some data centers have already proposed. Once operating, we need reporting on the actual water and energy use. The cumulative impact must be understood to ensure capacity and resiliency. Water withdrawers from the Catawba utilize a Low Inflow Protocol during drought to help stretch the available supply. Large data centers need conservation plans that comply with this plan. It is hypocritical to ask residents and some businesses to restrict water use while permitting facilities that cannot or will not do the same. Most years, there is plenty of water for drinking, irrigation, ecological flows, and industry in the Catawba. However, droughts such as 2001, 2007, and today expose our vulnerabilities. These droughts are more likely in a warming climate, and we are becoming less resilient with a growing population and industrial demands. Sustainable water management requires careful planning and robust coordination between users, including data centers."

Live staking is a streambank restoration approach that reduces erosion and sediment pollution. This is the practice of planting dormant branch cuttings of native plants along streambanks (also known as riparian zones) to help hold soil in place along the waters' edge. Live stakes are planted along with native plant seeds and shrubs to create riparian buffers, which help prevent sediment from becoming a stream pollutant by securing the soil in place with good root systems. Riparian buffers also filter out other pollutants, such as chemicals, oils, fertilizers, and trash, before they enter our waterways.
