Large water-use proposals filed: Recent water-rights applications for the Dewey-Burdock in-situ uranium project and related filings propose intensive groundwater use — including plans to drill into the Inyan Kara and Madison aquifers that would amount to billions of gallons annually — and the Department of Agriculture & Natural Resources accepted public comment through Nov. 9 ahead of a Dec. 2 hearing. The proposals have been recommended for approval by the chief engineer of the water rights program.

Policy and funding responses mount: State lawmakers and officials moved to address shortages: Senate Bill 231 (2026) created a Water Infrastructure Development Fund seeded with $3 million, and officials said finding more funding would be a priority in the 2027 legislative session while late-October meetings outlined potential expansion projects totaling roughly $13 billion. Lawmakers signaled growing support to invest in water infrastructure to meet demand.

Streams and rural wells run dry: By late October 2026, stretches of Spring Creek were completely dry and multiple West River rural wells and homestead supplies were reported as running low or dry, with drawdowns visible at Angostura, Belle Fourche and Pactola reservoirs. These surface-water losses have been linked to low precipitation and declining aquifer support.
