| Summary: | Lakes of Alaska were analyzed by watershed and region of Alaska for the State of Alaska Salmon and People (SASAP) project. 188 watersheds and thirteen regions were assessed for number of intersecting lakes, area covered by lakes, and other lakes statistics as described in "Lake_Polygons.ipynb" in this package. Lakes data is based on the River Analysis Project (RAP) dataset as outlined in "A Riverscape Analysis Tool Developed to Assist Wild Salmon Conservation Across the North Pacific Rim" by Whited, D. C., J. S. Kimball, J. A. Lucotch, N. K. Maumenee, H. Wu, S. D. Chilcote, and J. A. Stanford (2012). Lakes polygons in the RAP dataset were provided directly by the authors (Waterbody_AK_RAP.zip) and are based on 1990s-era Landsat 4 and 5 satellite data, with methodology outlined in the publication above. More information on RAP can be found here: http://www.ntsg.umt.edu/rap/default.php. Regions are determined by the SASAP project and watersheds are based on HUC8 definitions from the International Joint Commission and sub-sub-drainages from the Canadian National Hydro Network.
