Bicyclists and hikers will have a unique chance to access and cross over the Missouri River at Cochrane Dam on Saturday, June 1 from 9 a.m. to 3 p.m. The dam is normally closed to public access, but NorthWestern Energy and Montana Fish, Wildlife & Parks are working together to provide this special opportunity for hikers and bikers to experience the trails along both sides of the Missouri River near Great Falls.
