Description:
Abstract:
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.
Purpose:
The data was collected for the purpose of developing a classification system for the Fish Creek Watershed.  This will guide research and aid in the management of the natural and human-modified environment.

Methodology:
Methodology Type: Relative lake depth information was assigned to each lake using the SAR-based classification scheme of bedfast and floating ice lakes developed by Grunblatt and Atwood (2014).; Lake surface area dynamics were classified from a dense time series of Landsat TM, ETM+, and OLI imagery available from 1985 to 2015. Trends of different multi-spectral indices were calculated for each pixel on all unobstructed observations during peak summer season (July, August) between 1985 and 2014.

Attribute Definition:
Lake surface area dynamics were extracted from a dense time series of Landsat TM, ETM+, and OLI imagery available from 1985 to 2014.  All cloud-free pixels were analyzed over this 30 year period and classified as either water or non-water.  This information was aggregated for the entire time series and trends in lake surface area were categorized over the entire time series as: 1: expanding lakes, 2: shrinking lakes, 3: dynamic lakes, and 4: stable lakes.
