A 40-mile stretch of Gallatin River has been formally declared impaired this month after the U.S. Environmental Protection Agency approved the listing by the Montana Department of Environmental Quality. The stretch runs from the border of Yellowstone National Park to Spanish Creek.
The impairment designation comes after five consecutive years of toxic algal blooms and several environmental groups petitioning the DEQ.
The next step in this process is to monitor water quality and determine a total maximum daily load, or TMDL, which could take upwards of six years to complete.
“A TMDL is the calculation of the maximum amount of a pollutant allowed to enter a waterbody so that the waterbody will meet and continue to meet water quality standards for that particular pollutant,” according to the EPA. The EPA acknowledges that identifying these pollutants and their effects can be an “iterative process.”
Back in April, the Montana DEQ stated that, “excess algae growth is usually the result of nitrogen and phosphorous, however the assessment revealed that the river is not impaired for nitrogen and phosphorus when compared to existing numeric criteria. Instead, the assessment of the response variables, such as macroinvertebrate communities and ash-free dry weight, indicate that the river is impaired by algal growth. Photos, videos and testimonials submitted with the petition further supported this outcome.” The direct cause of these algae blooms has yet to be determined.
“There has always been more algae downstream of Big Sky, but we have started to see more algae upstream as well,” said Kristen Gardner, executive director of the Gallatin River Task Force.
Some pollutants are easy to trace and figure out where they are coming from, these are point source pollutants. Nonpoint source pollutants originate from a variety of locations and are carried into storm drainage systems and creeks by storm water and other runoff.
Gardner wants the community to know that the Gallatin River Task Force has not been “sitting around waiting” for the river to be declared as impaired. They’ve contributed to the community efforts in upgrading the wastewater treatment plant in Big Sky, a number of large-scale restoration projects going on around the Gallatin, as well as a native landscaping program that encourages everyone to do their part in protecting the river by choosing native plants that don’t require large amounts of water or fertilizer.
Gardner also stated that the DEQ will be spending an additional $500,000 to $1 million on the river monitoring efforts, and that the GRTF will be working alongside the DEQ to help connect their team with the community.

We will combine the heart-opening powers of cacao with the transcendental powers of breathwork and sound. Together, these practices will give us the opportunity for a deep inward journey and peak state experience. This experience can activate and clear the chakras, release trauma, reset the nervous system, connect us with higher consciousness, and help us achieve self-actualization.

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.
