North Dakota Surface Water Data

Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in Wisconsin. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

North Dakota Ground Water Data

Data from wells, springs, test holes, tunnels, drains, and excavations in North Dakota; well location data includes information such as latitude and longitude, well depth, and aquifer. Groundwater level data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

Nutrient contributions from point sources, combined sewer overflows, and wastewater treatment plants for selected Chesapeake Bay watersheds

The dataset contains estimates for total nitrogen and total phosphorus loads from point sources, combined sewer overflows, wastewater treatment plants that discharge to surface water for selected Chesapeake Bay watersheds. For source information, please refer to the process steps in this metadata report.

Seasonal precipitation for selected Chesapeake Bay watersheds

This dataset provides estimates of annual and seasonal precipitation for selected Chesapeake Bay watersheds. Season 1 is November-February; season 2 is March-June; and season 3 is July-October.

Peak Flow File November 14 2016

A comma separated values (csv) file that is a snapshot of the U.S. Geological Survey peak flow file on November 14, 2016. The file lists agency, station identification, water year, peak date, peak values, peak qualification codes, gage height values, gage height qualification codes, and year of last peak for all stream gaging stations for which peak streamflow has been recor

Reservoir storage for selected Chesapeake Bay watersheds

This dataset contains values of normal reservoir storage in units of acre-feet per km2, for three time periods: 1992, 2002, and 2012. Values are derived from a slightly-modified version of the National Inventory of Dams (NID) 2013 dataset, for which approximately 10% of records had the dam completion date estimated.

Peak Flow File November 19 2008

A comma separated values (csv) file that is a snapshot of the U.S. Geological Survey peak flow file on November 19, 2008. The file lists agency, station identification, water year, peak date, peak values, peak qualification codes, gage height values, gage height qualification codes and year of last peak for all stream gaging stations for which peak streamflow has been recorded

Percent agricultural land enrolled in the Conservation Reserve Program for selected Chesapeake Bay watersheds

These data report the percent of agricultural land, within each selected Chesapeake Bay watershed, that is enrolled in the Conservation Reserve Program (CRP), based on county-level data for each year from the U.S. Department of Agriculture Farm Service Agency.

Palmer Hydrological Drought Index (PHDI) values for selected Chesapeake Bay watersheds

This dataset contains values of the Palmer Hydrological Drought Index (PHDI) for annual and seasonal periods from 1985-2012. Values are derived from data based on National Climatic Data Center (NCDC) climate divisions, of which there are 344 in the U.S.

Static soils, climate, hydrologic, topographic, and geographic characteristics for selected Chesapeake Bay watersheds

This dataset contains values of soils, climate, hydrologic, topographic, and other geographic characteristics such as drainage area. These are considered "static" characteristics, which do not change over the time period of this study.

Percent impervious surface for selected Chesapeake Bay watersheds

This dataset contains watershed means of estimated percent impervious surfaces for three time periods: 1992, 2002, and 2012. Estimates are based on coefficients derived from comparing land use of the 2012 NAWQA Wall-to-wall Anthropogenic Land-use Trends (NWALT) product to the 2011 National Land Cover Database (NLCD) imperviousness, then applying those coefficients to previous yea

Chesapeake Bay non-tidal network shapefiles for selected watershed boundaries

This metadata report documents a shapefile of watershed boundaries for 84 selected United States Geological Survey (USGS) water quality stations that are part of the Chesapeake Bay non-tidal network (NTN).
