                                            Starting this fall, Big Sky Resort will become Montana’s first public ski area to use treated wastewater for snowmaking, following Yellowstone Club’s 2023 approval as the first in the state. 
The recycled wastewater is “highly treated” from the broader Big Sky community’s new $50 million wastewater treatment facility and will “[recharge] the aquifer, increasing late season water flow, and improving riparian and river health,” according to a joint press release from Big Sky Resort and Lone Mountain Land Company, which owns Spanish Peaks. The operation will take place on Spanish Peak slopes, accessible to Big Sky Resort guests. 
“Recycled snowmaking is a science-backed solution that protects the Gallatin River and every community downstream,” Big Sky Resort President and COO Troy Nedved stated in the release. 
The project received support from numerous environmental groups, including Trout Unlimited, American Rivers, Greater Yellowstone Coalition, Gallatin River Task Force, the Association of Gallatin Agricultural Irrigators, and the Big Sky County Water and Sewer District.
