    • Fish Creek Watershed Lake Classification, NPRA, Alaska, 2016

    Metadata Updated: January 22, 2026

    This study focuses on the development of a 20 attribute lake cover classification scheme for the Fish Creek Watershed (FCW), which is located in the National Petroleum Reserve-Alaska (NPR-A). The GIS dataset consists of 4,362 lakes (which were extracted from a 5m resolution IfSAR/orthophoto image) covering 18% of the 4,900 km2 FCW and provides information on lake morphometry, hydrologic connectivity, surface area dynamics, surrounding terrestrial ecotypes, and other important aquatic conditions. The FCW lake cover classification scheme provides lake specific information for an arctic watershed that will guide research and aid in the management of the natural and human-modified environment.
