DescriptionReach A18 is 2.5 miles long and extends from Laurel to the mouth of the Clarks Fork River. The reach is classified as Unconfined Anabranching (UA), which is characteristically one of the most dynamic reach types on the river. The reach has one large island and even though it is fairly intensively armored through Laurel, there has been over 1,100 feet of southward channel migration since 1950 at one location about ½ mile downstream of the bridge.TypeTextGenredocumentsLanguageeng Date2016-03-16SubjectRivers--MontanaYellowstone RiverYellowstone River WatershedContributing InstitutionMontana State LibraryGeographic CoverageYellowstone RiverMontanaDigital CollectionYellowstone River Corridor StudyDigital Formatapplication/pdfDigitization SpecificationsBorn PDF documentsCopyrightCC0
