The Hydrology Polygon Feature Class defines areas of open water features on RSL. The polygon feature class is composed of National Hydrography Dataset (NHD) Plus Polygons and where the NHD Plus layer was insufficient, water bodies were digitized from 2010 National Agricultural Inventory Program (NAIP) 10 meter aerial imagery.

The Hydrology Polygon Feature Class defines areas of open water features on RSL. The polygon feature class is composed of National Hydrography Dataset (NHD) Plus Polygons and where the NHD Plus layer was insufficient, water bodies were digitized from 2010 National Agricultural Inventory Program (NAIP) 1 meter aerial imagery. Areas of open water are known to fluctuate based on rainfall and other factors, and therefore this dataset may not be accurate for other time periods.

On May 25, 2014, a rain-on-snow induced rock avalanche occurred in the West Salt Creek Valley on the northern flank of Grand Mesa in western Colorado. The avalanche traveled 4.6 km down the confined valley, killing 3 people. The avalanche was rare for the contiguous U.S. because of its large size (54.5 Mm3) and long travel distance. To understand the avalanche failure sequence, mechanisms, and mobility, we mapped landslide structures, geology, and ponds at 1:1000-scale. We used high-resolution, Unmanned Aircraft System (UAS) imagery from July 2014 as a base for our field mapping. Here we present the map data and UAS imagery. The data accompany an interpretive paper published in the journal Geosphere. The full citation...

Data release contains 1710 polygons representing small bodies of water within 500 meters of poultry feeding operations on the Delmarva Peninsula. Ponds were identified using the USDA's National Agriculture Imagery Program's 2016 and 2017 products. Poultry feeding operations were described in location by Soroka and Duren (2020).
