It’s time to rethink reuse

On Oct. 11, snow returned to the upper Gallatin watershed, and for the first time since late spring, the water bank began recharging.
In Big Sky, as with all communities across the Mountain West, fresh water comes primarily in the form of winter’s snow, as inches turn to feet and next summer’s water supply is stored in the alpine until spring.
The continuation of this cycle is critical to river health—and to the supply of fresh water in our homes and businesses—but its persistence is far from guaranteed.
As climate change continues to wreak havoc on the delicate natural balance of our headwaters ecosystem, the availability of fresh water becomes less likely every passing year. Warming temperatures mean fewer days of snowfall, shorter winter seasons and faster spring snowmelt. All of this adds up to a concerning sum—a future without ample cold, clean flows for the Gallatin River.
But just as the season’s first snow offered a sigh of relief from the dry, hot summer, proactive conservation and resilience in the face of climate change can result in a more hopeful outcome. Recently, we’ve taken major steps forward.
Earlier this year, engineers broke ground on a new, upgraded wastewater treatment plant in Big Sky. This facility will have major positive impacts on the health of the Gallatin River, as water treated there will have 90 percent less bacteria, 99 percent less nitrogen and 99 percent less phosphorus.
This highly-treated water allows us to prioritize wastewater recycling options that aren’t available currently, such as groundwater recharge and snowmaking. A snowmaking project is underway at the Yellowstone Club, and the Gallatin River Task Force is working with Big Sky Resort on a feasibility study for their terrain.
By mimicking traditional snowfall patterns, snowmaking with highly-treated wastewater will recharge our aquifers, improve streamflows in our waterways and mitigate adverse impacts from climate change. This is particularly important as drought, such as we experienced this year, becomes the norm, not an anomaly.
While using wastewater for snowmaking might seem irksome to some, it’s important to note that studies reviewed by the task force show no adverse environmental impact from doing so. In fact, as far as discharge options go, this is far more favorable than using wastewater for landscaping irrigation, although with the new treatment plant, this process will also be radically improved. Snowmaking also helps avoid direct discharge into the Gallatin, which the task force has long opposed.
Because our water supply is so reliant on snowfall, and because all climate models predict a significant decrease in snowfall, this reuse option is particularly encouraging, although there are others that could also improve water quality and bolster water quantity.
Groundwater recharge, in which treated wastewater is pumped into underground “infiltration galleries” connected to aquifers, could also go a long way toward augmenting our water supply as we prepare for a drier future. Because the wastewater is highly-treated, we believe there is little threat to water quality and river health, and indeed this method would increase in-stream flows as underground aquifers feed springs that feed the Gallatin.
As the weather shifts, forecasters are predicting a cold, snowy winter, which is good, but far from a guarantee of ample water supply come spring. For now, only one thing is clear: our water supply issues are not going away. Climate change and human use are driving our water levels down. This decrease in supply exacerbates water quality issues, further threatening aquatic wildlife, our recreation economy and public health.
To solve what feels like a monumental problem, we have to be creative, and we have to be proactive. By doing so, we can set the sustainability standard for headwaters communities across the American West. It will take outside-the-box thinking, but based on recent progress, it appears we’re heading in the right direction.

We all are familiar with using a limited palette, but do you use one? Do you know how to use a limited palette to create different color combinations? Are you tired of carrying around 15-20 different tubes when you paint plein air? Have you ever wanted to create a certain “mood” in a painting but failed? Do you create a lot of mud? Do you struggle to achieve color harmony? All these problems are addressed in John’s workbook in clear and concise language!
Based on the bestselling “Limited Palatte, Unlimited Color” workbook written by John Pototschnik, the workshop is run by Maggie Shane and Annie McCoy, accomplished landscape (acrylic) and plein air (oil) artists,exhibitors at the Big Sky Artists’ Studio & Gallery and members of the Big Sky Artists Collective.
Each student will receive a copy of “Limited Palette, Unlimited Color” to keep and take home to continue your limited palette journey. We will show you how to use the color wheel and mix your own clean mixtures to successfully create a mood for your paintings.
Each day, we will create a different limited palette color chart and paint a version of a simple landscape using John’s directives. You will then be able to go home and paint more schemes using the book for guidance.
Workshop is open to painters (oil or acrylic) of any level although students must have some basic knowledge of the medium he or she uses. Students will be provided the book ($92 value), color wheel, value scale and canvas papers to complete the daily exercises.
Sundays, April 14, 21 and 28, 2024
Noon until 6PM.
