Flint TMDL Planning Area Overview


Map 1: Location of the Flint Creek Watershed

(click on map to enlarge)

Location of the Flint Creek watershedThe Flint Creek watershed is located in the northern Rocky Mountains of southwestern Montana. The watershed covers an area of approximately 500 square miles, from Georgetown Lake to the Clark Fork near the city of Drummond (Map 1). An inter-basin diversion from the East Fork Rock Creek Reservoir also contributes flow to Flint Creek through its tributary, Trout Creek. Land use in the Flint Creek watershed is primarily forest and grazing, with agriculture in the valleys. Philipsburg is the only urban area of considerable size, but other communities are found scattered throughout the watershed especially at lower elevations. Development of vacation properties near Georgetown Lake has been accelerating recently. Historically, the Flint Creek watershed had considerable mining activity, some of which continues to the present.


Water quality sampling of streams in the Flint Creek watershed showed that several waterbodies are not meeting designated uses and are considered impaired for excess metals, sediment, and nutrients (Figure 2 below). The TMDL project focused upon streams identified as impaired by pollutants on Montana’s 2012 303(d) List. Sediment and metals TMDLs were completed in 2012 and nutrients TMDLs were completed in 2013, published in two separate documents.

TMDL Documents 


TMDLs were published in two separate documents for this project. Metals and sediment TMDLs were completed in 2012 and nutrients TMDLs were completed in 2013. Both documents include recommended land management activities for improving water quality in the Flint Creek watershed, as well as a monitoring strategy to evaluate progress toward attainment of water quality standards. For information on possible funding to implement water quality improvement projects, or for technical help, see DEQ's Nonpoint Source Program webpage or contact Laura Andersen (landersen3@mt.gov, 406-444-0549) or Robert Ray (rray@mt.gov, 406-444-5319).


Nutrients TMDLs

The "Flint Nutrients TMDLs and Water Quality Improvment Plan" was approved by EPA on December 30, 2013 and can be found on DEQ's Final TMDL Documents webpage. Electronic copies are also available at the Philipsburg public library (102 S. Sansome St.) and the State Library in Helena (1515 East 6th Ave).  


A public meeting was held December 4, 2013 at the Granite County Museum and Cultural Center in Philipsburg (135 Sansome St.) where Paul Kusnierz presented the document and answered questions. The presentation from the meeting is available in the table below. The public notice contains additional meeting details.  


Metals & Sediment TMDLs

The "Flint Creek Planning Area Sediment and Metals TMDLs and Framework Water Quality Improvment Plan" was approved by EPA on October 2, 2012. The document is posted on DEQ's Final TMDL Documents webpage. A public meeting was held in Philipsburg on March 7, 2012. Jim Bond and Darrin Kron gave a presentation (available in the table below) discussing the draft sediment and metals TMDL document.
