Ecology created SMA_Jurisdiction_Streams (also known as SMA_Arcs_Adopt) by selecting appropriate flowlines from the National Hydrographic Dataset "NHDFlowline.lyr" as maintained by the Department of Ecology in conjunction with the USGS. This dataset can be used with linear referencing and is synchronized with the March 2019 version of NHD.The original official list of streams that meet the 20 cubic feet per second (cfs) mean annual flow criteria found in state rule at WAC 173-18 HAS BEEN SUPERSEDED by lists contained in Ecology-approved shoreline master programs.Each local government master program shall include a list of streams constituting shorelines of the state within the jurisdiction of the master program that complies with the requirements of RCW 90.58.030 (2)(d). When such master program is approved by the department, subsequent to the effective date of this provision, the list within the master program shall be the official list for that jurisdiction and shall supersede the list contained herein. Streams and rivers westof the Cascades crest with a mean annual flow of 1,000 cfs or greater, and eastof the Cascades crest with either a mean annual flow or 200 cfs or more orthe portion downstream from the first 300 square miles of drainage areas are classified as shorelines of statewide significance.
