Water District’s TWG shows far more water in basin

66.9 Million acf of water in storage

Indian Wells Valley Water District (IWVWD) Tracy Leach–   The Indian Wells Valley Water District (Water District) is pleased to announce significant progress in our ongoing commitment to securing a sustainable water future for our community. On February 23, the IWV Water District filed papers to initiate the first substantive phase of the Basin Adjudication proceedings, marking a pivotal moment in our commitment to managing and preserving groundwater resources effectively. A court hearing regarding the Adjudication process was held on Friday, March 22, at 1:30 PM.

As part of this milestone in the Adjudication, the Water District has shared a portion of an in-depth report called the White Paper on Groundwater in Storage in the Indian Wells Valley. This report, crafted by a team of groundwater scientists and engineers known as the Technical Working Group (TWG), offers meticulous analyses detailing the current state of groundwater in storage in the IWV Basin.

The findings from the TWG’s assessment reveal a substantial amount of groundwater resources within the Basin. By leveraging the expertise of six prominent hydrogeological consulting firms and employing advanced scientific methods, the TWG has determined that the Indian Wells Valley possesses a much larger volume of groundwater than previously thought. According to the TWG’s analysis, there’s approximately 66.9 million acre-feet of groundwater stored in the Valley, and at least 37.5 million acre-feet of it is fresh groundwater.

These estimates surpass earlier projections outlined in the Groundwater Sustainability Plan, highlighting the importance of ongoing scientific research in managing our water resources. Additionally, the TWG’s work has shed light on the potential for utilizing brackish or saline water resources within the Basin, which could provide an additional 40.0 to 53.8 million acre-feet of water. Though treatment is needed to reduce Total Dissolved Solid concentrations, these resources offer a promising avenue for sustainable water supply solutions.

“The release of the White Paper underscores IWVWD’s commitment to transparency, collaboration, and evidence-based decision-making in water management. As we move forward, the IWVWD remains dedicated to integrating these findings into ongoing discussions and initiatives to promote Basin sustainability. We believe that by harnessing the best available science and fostering collaboration among all parties, we can achieve a resilient water future for the Indian Wells Valley community.” – Ronald Kicinski, President of the Indian Wells Valley Water District.
