310 Permits
Within the Missoula City limits of 1946, the Missoula County Commissioners administer the Natural Streambed and Land Preservation Act of 1975. 310 Permits are required for any activity conducted by a non-governmental body that results in a change in the state of a natural perennial-flowing stream or river, its bed or its immediate bank. Missoula County's 310 jurisdiction includes the Clark Fork River and Rattlesnake Creek within the 1946 Missoula City limits.
