Percentage Differences Streamflow

A comma separated values (csv) file that is a snapshot of percent difference between November 19, 2008 and November 14, 2016 peak streamflow. The file lists station identification, water year, original (2008) peak Q, current (2016) peak Q and percent difference calculated per water year. The percent difference was calculated as the absolute value of [(current peak Q - o

Estimates of inorganic nitrogen deposition from precipitation for selected Chesapeake Bay Watersheds

This dataset contains estimates of the yearly sum of nitrogen atmospheric deposition of inorganic nitrogen in selected Chesapeake Bay watersheds from 1985-2012. Data for 1985-2012 were downloaded from the National Atmospheric Deposition Program.

Wheat Corn Soy Estimates Red River of the North Basin

These data describe the percent of cropland harvested as wheat, corn, and soybean within each basin (basins 1-8, see accompanying shapefiles). Data are available for other crops; however, these three were chosen because wheat is a traditional crop that has been grown for a long time in the Basin and corn and soybeans have increased in recent times because of wetter conditions, the

Total Phosphorus Flux/Load Estimates Red River of the North Basin

The dataset contains estimates of annual flow and annual flux in kilograms for six sites in the Red River of the North Basin (identified as basin 1, 2, 3, 4, 5, and 8). The shape files that are part of this data release document the basins and the streamgage locations are also provided in an associated shape file.

Wastewater Treatment Plant Total Phosphorus Flux Load Estimates Red River of the North Basin

The dataset contains estimates for total phosphorus flux from wastewater treatment plants that discharge to surface water within the Red River of the North Basin in the United States and subbasins. Shapefiles defining the subbasins are available as part of the same data release in which these data are published. Estimates of wastewater treatment plant total phosphorus flux (or load) were ca...
