DescriptionReach A17 is 7.6 miles long and is located just above Laurel. The reach is classified as Unconfined Anabranching (UA), which is characteristically one of the most dynamic reach types on the river. The river is flowing in the alluvial valley with minimal influences of the valley wall and through numerous forested islands. There are sites in Reach A17 where the river has migrated almost 1,000 feet since 1950.TypeTextGenredocumentsLanguageeng Date2016-03-16SubjectRivers--MontanaYellowstone RiverYellowstone River WatershedContributing InstitutionMontana State LibraryGeographic CoverageYellowstone RiverMontanaDigital CollectionYellowstone River Corridor StudyDigital Formatapplication/pdfDigitization SpecificationsBorn PDF documentsCopyrightCC0
