资源简介：
These streamlines reflect a stream gradient exercise, conducted for Southeast Alaska. The goal was to delineate streams with calculated stream gradient in 100 meter sections, allowing a query to find connected waters below the 12% gradient over that stretch to gauge a possible extent of anadromy. File generated from running the Extract Data solution, clipping data around the Hoonah area.
