DescriptionReach A4 is approximately 3.3 miles long, extending from near the Sweet Grass County Fairgrounds downstream to the Boulder River confluence. Reach A4 is very dynamic with active channel migration, threats to infrastructure, bank armor, flanked barbs, and active riparian recruitment on raw gravel bars. The most dynamic portion of the reach is upstream of the Highway 191 Bridge; in spring of 2013 a large meander formed a 1,500 foot long chute cutoff near the fairgrounds which abandoned about 3,500 feet of channel to the south.TypeTextGenredocumentsLanguageeng Date2016-03-16SubjectRivers--MontanaYellowstone RiverYellowstone River WatershedContributing InstitutionMontana State LibraryGeographic CoverageYellowstone RiverMontanaDigital CollectionYellowstone River Corridor StudyDigital Formatapplication/pdfDigitization SpecificationsBorn PDF documentsCopyrightCC0
