    • USGS Dynamic Surface Water Extent (DSWE)-based Inundation Frequencies for Select U.S. Fish and Wildlife Service Mountain-Prairie Region Properties, North Dakota 1982-2020

    Metadata Updated: September 14, 2025

    This data release contains grids, in geographic tagged imaged file(.tif) format, summarizing inundation frequency of the U. S. Geological Survey (USGS) Dynamic Surface Water Extent (DSWE) Landsat Science Product at 114 National Wildlife Refuges throughout the U.S. Fish and Wildlife Service (USFWS) Mountain-Prairie Region (Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota, Utah, and Wyoming). The DSWE product provides long-term (1982 to present), high temporal resolution data (30-meter) on surface water inundation patterns that can help identify locations of past or current drought conditions. For each refuge, three files were produced using data from different periods: the baseline period (1982-2000), the evaluation period (2001–20), and the period of record (1982-2020). Inundation frequencies for each pixel were derived by dividing the total number of observations classified as any one of the DSWE water classes by the total number of observations of water extent or presence. This child item contains data for wildlife refuges within the state of North Dakota (ND). See keywords for specific refuges.
