Abstract: Flow lines were clipped from the National Hydrography Dataset (NHD) coverage for Norton Sound, the Alaska portion of the Yukon River, and the Kuskokwim River available from http://nhd.usgs.gov/data.html. In addition, flow lines for the Canadian portion of the Yukon River drainage were obtained from the Canadian National Hydro Network dataset available from http://www.geobase.ca/geobase/en/index.html. The flow lines clipped from the two datasets were merged to form a single flow line dataset for this project.

Purpose: To assess and compare the extent to which habitat features from four general categories (spatial isolation, habitat size, climate, and ecology) explain population structure in Chinook, chum and coho salmon from Norton Sound and the Yukon and Kuskokwim rivers.

Supplemental: This is a simplified version of the Flowlines data used in the project analyses. The flowlines were filtered using the Point Removal algorithm at a maximum tolerance of 50m. This dataset is for cartographic use only.
