About the CD

The Green Mountain Conservation District (GMCD) was organized on November 4, 1941 and is one of 58 conservation districts in Montana. A non-paid elected and appointed board of supervisors governs district activities. GMCD operations are partially funded by a 1.5 mill tax on county property, with the balance paid through grants from State and Federal resources.

State Conservation Districts began forming at the request of President Roosevelt in 1937 after Congress unanimously declared soil and water conservation a national policy priority.  The 1930’s financial disaster of the Great Depression, followed by the ecological disaster of the Dust Bowl, then the sustained drought in the Great Plains brought about this action.

The main function of GMCD is to promote conservation of natural resources. The primary activity of the board is to administer Montana’s Natural Streambed and LandPreservation Act, also known as the”310 Law.” It is a state law which requires that any person planning to work on or near a perennial stream or river on private or public land must first obtain a 310 Permit from the local conservation district.

The purpose of the 310 Law is to insure that projects will be carried out in ways that are not damaging to the stream or to adjoining landowners by following Construction and Design Guidelines.
