Madison And Upper Big Hole Watershed Assessments Ready For Public Review

Assessments of resource conditions on public lands within the Madison and Upper Big Hole watersheds are available for public review.

The Madison Assessment is located in Madison County of southwestern Montana and covers about 30,729 acres of public land on 39 grazing allotments, as well as 7,089 acres of unleased and unallotted public land.

The Upper Big Hole Assessment is located in Beaverhead County and covers about 5,900 acres of public land in 12 grazing allotments, as well as 432 acres of unleased and unallotted public land parcels. 

In preparing the assessments, the Dillon Field Office of the Bureau of Land Management evaluated each watershed’s resources according to the five standards for rangeland health. These standards include  maintaining properly functioning upland and riparian areas; assuring that water quality and air quality meet state standards; and providing for biodiversity. Forest health, fuel conditions, and recreational issues were also assessed.  

National Environment Policy Act (NEPA) documents will be prepared to analyze alternatives for revising management where resource concerns were found within these watersheds. The NEPA documents will be completed by resource specialists from the Dillon Field Office in coordination with grazing lessees, other agencies, and the interested public. 

The BLM welcomes public comments to help formulate alternatives and define issues for the environmental assessments. To be most useful, public comments must be submitted by January 22, 2010. These reports have been mailed to all individuals who expressed an interest in the projects and asked to be on the mailing list. If you would like to receive a copy of either watershed assessment report, please call the Dillon Field Office at (406) 683-8000, or email The reports are also available for review online at:

The BLM manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's mission is to sustain the health, diversity, and productivity of America’s public lands for the use and enjoyment of present and future generations. In Fiscal Year 2015, the BLM generated $4.1 billion in receipts from activities occurring on public lands.
