Completed TMDLs in the Bitterroot River Watershed

Total maximum daily load (TMDL) work was performed by Montana DEQ in the Bitterroot River watershed for a number of years. For TMDL planning purposes, DEQ divided the watershed into three separate TMDL planning areas: Bitterroot Headwaters, Bitterroot, and Upper Lolo (see map below). Individual TMDL documents were produced for these planning areas in 2003, 2005, and 2011. A fourth document was produced in 2014 that addressed impairments in all three planning areas; therefore this project was called the Bitterroot Watershed TMDL Project. Collectively, 56 TMDLs have been completed, a breakdown of which can be found below by TMDL document. A single table of all TMDLs completed in the watershed was compiled as Table A-1 in Appendix A of the Bitterroot Watershed TMDL document.

Document: Bitterroot Temperature & Tributary Sediment Total Maximum Daily Loads and Framework Water Quality Improvement Plan 

Document Completion Date: 2011

Document Locations: DEQ's TMDL webpage. Copies are also available at the Missoula, North Valley (Stevensville), Bitterroot (Hamilton), and Darby public libraries.

 

Project History Information:

A schedule for the temperature and tributary sediment TMDLs was created for stakeholders to track the progress of the project and is still available if you would like to view the project's history. A map of streams that were assessed for sediment (map size: 0.9 MB) as part of the Bitterroot TMDLs project, and the streams that were included in the 2007 sediment sampling field work, is also still available for viewing. Note that the map is not a reflection of the sediment TMDLs that were completed; streams with completed sediment TMDLs are shown in Table 3 below.

 

Presentations related to these TMDLs can be found on the Bitterroot Watershed TMDL Project Outreach page.

Success Story: 2014 Meadow Creek sediment delisting (removal of sediment impairment from the impaired waters list)

 

This document also addresses non-pollutant impairments in the Bitterroot Headwaters and Upper Lolo TMDL Planning Areas. 

Table A-1 in Appendix A of this document provides a list of all TMDLs that have been written in the watershed, all non-pollutant impairments that have been addressed, and in what document they are contained in (i.e., 2003 Upper Lolo, 2005 Blackfoot Headwaters, 2011 Bitterroot, or 2014 Bitterroot Watershed). 

 

Project History Information:

An overview of this project, as well as a map of the included streams, is contained on the Bitterroot Watershed TMDL Project Overview page. Presentations and the project updates related to these TMDLs can be found on the Bitterroot Watershed TMDL Project Outreach page.
