Points on streams and rivers where SMA jurisdiction begins as published in Chapter 173-18 WAC. This layer will not be updated. It is slowly becoming outdated as cities and counties update their list of SMA streams in their shoreline master program. See WAC 173-18-044 posted at http://apps.leg.wa.gov/wac/default.aspx?cite=173-18-044.Point locations were originally compiled for Ecology in 1972 by the US Geological Survey, Water Resources Division, Tacoma, WA, and released in STREAMS OF WASHINGTON UNDER THE REQUIREMENTS OF THE SHORELINE MANAGEMENT ACT OF 1971. Points were determined using multiple-regression techniques based on streamflow and basin precipitation records. Ecology has occasionally updated point locations, and added and subtracted points since 1972.
