The Virgin Valley Water District (VVWD) convened on Oct. 21 for a pivotal meeting that provided a clear, positive assessment of its financial health and delivered a landmark report that fundamentally reshapes the understanding of the region’s long-term water resources. The board received an overwhelmingly favorable annual financial audit and accepted the findings of an exhaustive four-year groundwater flow model study, which effectively alleviates community fears about Mesquite’s capacity for sustainable growth.

A clean bill of financial health

The meeting began with a review of the district’s finances for the fiscal year ending June 30, 2025, presented by McKay Hall of Hinton Burdick. The results were unequivocally positive, earning the district a “clean opinion,” which, as Hall explained, means the “information in the financial statements is materially correct.” Furthermore, he was “happy to note there were no findings this year in relation to the audit,” a testament to the district’s meticulous financial management.

The audit illuminated several key financial successes. The VVWD significantly outperformed its budget, logging $1,876,985 more in actual operating revenues and incurring $2,234,613 less in operating expenses than projected. This prudent fiscal stewardship has solidified the district’s financial foundation. The total value of the district’s net capital assets — excluding accumulated depreciation — reached a substantial $97,263,244, marking an impressive 6.16% increase ($5,640,154) over the previous year.

Moreover, the district has been actively reducing its debt burden. Long-term liabilities decreased by $2.1 million, settling at $27.4 million by the end of Fiscal Year 2025. The net pension liability also saw a reduction of $151,000. Looking at the five-year analysis, Hall pointed to an upward trend in total equity, which he called “important to watch because it’s a pretty good indicator of the health of an organization.” The unrestricted net position, the resources the district has “at your beck and call,” has also been trending upward since 2022. Board President Adam Anderson’s query about potential concerns was met with confidence, as Hall affirmed the management team is “focused in on what they’re doing and they’re paying attention to” and “takes their responsibility very seriously.” The board extended their gratitude to district CFO/accountant Wesley Smith for his outstanding efforts.

Groundwater model delivers robust estimate

The bulk of the meeting was dedicated to a presentation by Josh Simpson of Glorieta Geoscience on the Development of a Groundwater Flow Model to Estimate Perennial Yield in Nevada Basin 222. The study, which began in November 2020, was undertaken to ensure the current water allocation for Mesquite is sustainably sourced and, crucially, to determine the possibility of additional future water rights. This was the “final phase of the investigation,” employing advanced technologies to create a more defensible estimate than older, traditional methodologies.

Simpson clarified that the study was performed by the district to “be good stewards” of its resources, noting that the Division of Water Resources has encouraged reevaluation of perennial yield estimates in many basins. Perennial yield is the critical metric: “the amount of usable water from a groundwater aquifer that can be economically withdrawn and consumed each year for an indefinite period of time without depleting the source.” It represents the sustainable, long-term rate of withdrawal.

The team, including Paul Drakos, P.G., Jim Riesterer, P.G. and Holly Swarner, developed a sophisticated, two-step process. They first used a basin characterization model (a climate model) to determine three key output parameters, which were then used as direct input for a regional scale groundwater flow model. This approach allowed them to calibrate the model to extensive field data, including Virgin River stream flow and evapotranspiration, providing a high degree of confidence in the final result.

A key challenge was modeling the hydrogeologic properties of the basin, especially the Muddy Creek formation where the district’s wells are located. The team utilized geophysical survey results and Triangulated Irregular Networks (TINS) to create an accurate subsurface map. They also considered external stresses, running simulations where pumping outside the basin, such as in St. George, was doubled. The conclusion was reassuring: “All of those simulations came to the same conclusion: pumping and change of pumping outside the pumping…don’t have a substantial influence” inside the Virgin Valley Basin.

The critical conclusion: Refuting community fears

Once the model was calibrated to accurately simulate non-pumping and mid-1990s pumping conditions — showing the zone of influence around the wells is “actually really small” — Glorieta Geoscience presented the final, key finding. The estimated perennial yield within Basin 222, the Nevada portion of the Lower Virgin River Basin, is 20,421 acre-feet per year of recharge. Simpson stressed that this value is “defensible, and it’s a robust methodology that we used to obtain this value.”

The implication of this finding is profound for the Virgin Valley’s future. The district currently draws approximately 7,000 acre-feet a year, while the state water engineer has allocated Mesquite up to 12,271 acre-feet annually. The new estimate is nearly double the current allocation, directly countering pessimistic community assertions that Mesquite has overbuilt its capacity.

When asked if a widely circulating comment that Mesquite would be “out of water by 2035” could be definitively called false, Simpson replied with a clear affirmation of the model’s strength. “You continue the pumping that you’re pumping at right now, the model suggests that you wouldn’t be out of water. That’s what the model suggests.” Asked if the population could be doubled based on the data, Simpson estimated, “I think that could be done.”

The study bolsters the district’s current conservation achievements, which have reduced water loss to less than 10%. Furthermore, the 2023 Water Master Plan, which projected 8,246 acre-feet of use in 2024, proved conservative, as the actual use was 11% less, at 7,349 acre-feet. This efficiency, coupled with low per-resident usage in developments like Sun City (6,000 gallons/month versus a 9,000-gallon allocation), provides a strong foundation for future growth toward the 2080 projected population of 73,000.

Board President Adam Anderson praised the report as “a treasure for the valley.” The board accepted the study and directed staff to coordinate a presentation with the Nevada State Engineer, hoping the data will support potential future water rights permits. They also discussed future simulations, including stress-testing the model with 24/7 pump operation and creating a more refined model for future well placement planning.

In other news, conservation specialist Nathalie Anderson reported on the success of the “Imagine A Day Without Water contest” and the upcoming launch of the Water Ambassador program. Operations updates included good progress on Treatment Plant #35 and the imminent start of the Hafen/Levitt Lane Project on October 27th.

The findings from the Glorieta Geoscience study provide the residents of the Virgin Valley with a scientific basis for confidence in their water future, shifting the narrative from scarcity to sustainable, managed growth.
