Project Overview

The Sheep Creek watershed is located in Meagher County, Montana (Figure 1), near White Sulphur Springs, and is approximately 195 square miles in area (124,500 acres). Sheep Creek (see photo below) is a tributary to the Smith River within the Upper Missouri River basin (hydrologic unit code 10030103). From the Fall of 2014 through 2016, the Water Quality Planning Bureau at Montana DEQ conducted a watershed-wide assessment of streams in the Sheep Creek watershed. The purpose of the assessment was to determine the overall health of the streams in the Sheep Creek watershed, and determine if any water quality issues existed in those streams. As a result, two total maximum daily loads have been written for Sheep Creek, one for aluminum and one for E.coli. See the Sheep Creek TMDL Development page for more information.

Why is DEQ Interested in Sheep Creek?

With existing impairment listings from past evaluations and a new proposed copper mine, Sheep Creek is a prime candidate stream for water quality assessment. There are also engaged groups of stakeholders in the watershed that are interested in the issues surrounding Sheep Creek and its tributaries.

 

 

Watershed Risk Assessment Process

Since DEQ does not have the resources to look at every stream in the watershed, a risk-based approach was used to prioritize which streams were assessed. Streams that have the potential to be impaired by either a pollutant (e.g., sediment, nutrients, metals, etc.), or non-pollutant (e.g., flow alteration, habitat alteration, etc.) will be prioritized based on risk (need of restoration) and resource value. This projects also included streams that were previously identified as impaired by a pollutant from past assessments. The below diagram outlines the water quality assessment and planning process used by DEQ.  

 

 

 

Sheep Creek Watershed Monitoring & TMDL Development

In 2015, DEQ monitored the below list of streams for metals, nutrients, and temperature, and Sheep Creek was also monitored for E. coli and sediment. The 2015 sampling and analysis plans and a map of the monitoring locations can be found on the Monitoring and Assessment page.  

  • Sheep Creek 
  • Big Butte Creek* 
  • Moose Creek 
  • Calf Creek 
  • Little Sheep Creek*
  • Nugget Creek 

*Ongoing monitoring being conducted by Montana DEQ and Tintina Resources

 

As a result of the 2015 monitoring and water quality assessments, Sheep Creek was found to be impaired (not meeting its water quality standards) for aluminum and Escherichia coli (E. coli). Two total maximum daily loads (TMDL) were then written for Sheep Creek. Additional TMDL information can be found on the Sheep Creek Watershed TMDL Development page. 

 

Opportunities for Local Stakeholder Collaboration

DEQ relies on input from people who live and work in these watersheds to inform the scope of our work throughout this planning process. Opportunities for partnerships between DEQ and stakeholders may include:

  • Input on sampling design – which waters to monitor and where
  • Input on water quality issues of interest or concern
  • Volunteer monitoring program development/capacity-building
  • Landowner outreach to help facilitate monitoring on private lands
  • Support for local watershed restoration planning efforts
