The Boulder-Elkhorn TMDL Planning Area (TPA) is completely contained within Jefferson County and includes the towns of Basin, Boulder, and Elkhorn, and the Elk Park area. It encompasses the entire Boulder River watershed from its headwaters to the confluence with the Jefferson River at Cardwell. The TPA coincides with the 1002006 fourth-code hydrologic unit code (HUC), and is bounded by the continental divide on the west, the Elkhorn Mountains to the north, and Bull Mountain to the southwest. "Elkhorn" is included in the TPA name to differeniate between the Boulder River watershed near Big Timber, MT.
The Montana Department of Environmental Quality has identified 14 streams with water quality impairments in the Boulder-Elkhorn TPA. They are shown in both the table to the right and the map below. Impairments include nutrients, metals, sediment, and temperature. The TMDL planning process for this TPA incorporates a combination of water quality sampling and hydrologic modeling to further identify and quantify nutrient, metal, sediment, and temperature contributions from all significant sources.
The table identifies which streams have nutrients, metals, and/or sediment listed impairments. For complete information on each stream's probable impairment causes and sources, see DEQ's Clean Water Act Information Center. Search by the "Boulder" TMDL Planning Area within Step 2 on the web site (you do not need to select anything else in Step 1 or Step 2).
PROJECT SCHEDULE FOR NUTRIENT, METAL, SEDIMENT, AND TEMPERATURE TMDLS
Nutrients and metals TMDLs are currently under development in the planning area and are projected to be complete by the end of 2010. Water quality sampling for both nutrients and metals was conducted in June and August of this year. Additional sampling may take place next year. Sediment and temperature TMDLs are slated to begin next year as well (2010). A complete project schedule will be posted in the near future.
BOULDER-ELKHORN PLANS & DOCUMENTS
The nutrients and metals sampling and anlaysis plan (SAP) is posted on the Boulder Elkhorn Documents page. The SAP shows all 2009 sampling locations and the parameters collected at those locations. Future SAPs for sediment and temperature assessments will be posted as they are developed.
BOULDER-ELKHORN ADVISORY GROUP PAGES
These pages relate to the members of the Boulder-Elkhorn Watershed Advisory Group (WAG) and Technical Advisory Group (TAG). Information, presentations, and handouts from the October 8, 2009 meeting in LaHood Park, MT can be found on these pages.
