Maximum likelihood logistic regression is used to estimate drought probabilities for selected Virginia rivers and streams 5 to 11 months in advance. Hydrologic drought streamflow probabilities for summer months are provided as functions of streamflows during the previous winter months. This application allows the display and query of these drought streamflow probabilities for Virginia streams.

Light Detection And Ranging (Lidar) generates extremely accurate (vertical and horizontal) location information and has long been a desired product for the Upper Mississippi River System (UMRS).

Bathymetric data are collected with an automatic survey system and processed in a Geographical Information System (GIS). Through interpolation the individual points of water depth are converted into a water depth map.

Land/water is one of the classification attributes in the land cover/use data sets created by UMESC from aerial photography. These data are redistributed here as shape files with the boundaries of the region's 1:24,000-scale USGS quadrangles added to the data. 

The Upper Mississippi River Restoration (UMRR) Program Long Term Resource Monitoring (LTRM) element has collected millions of records of information over 20+ years. Fisheries, water quality, vegetation, and invertebrates have all been sampled. Geographic locations were collected for all sampling points. 

This mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where surface-water, groundwater, springs, and atmospheric data has been collected.

This tool allows the user to view several scanned and georeferenced historic map image mosaics. Data is available for viewing by selecting the layer list button described below, and checking the boxes next to the data layers of interest. There are other tools that allow map creation, distance and area measurements, and drawing tools.                  

In 1998 the Upper Midwest Environmental Sciences Center (UMESC) began aquiring digital orthophoto quadrangles (DOQ) for the Upper Mississippi River floodplain to georeference the center's aerial photography and land cover/use data. As these data become available, the files are compressed and placed online so others can also use them.

The Virginia Water-Monitoring-Sites Mapper is an interactive map of Virginia water monitoring-site locations from the USGS National Water Information System. It provides access to surface water, groundwater, and water quality monitoring data for active sites.

The West Virginia Water-Monitoring-Sites Mapper is an interactive map of West Virginia water monitoring-site locations from the USGS National Water Information System. It provides access to surface water, groundwater, and water quality monitoring data for active sites.

Scientists refined the existing national-scale "De facto Reuse Incidence in our Nation's Consumable Supply" (DRINCS) model for the Shenandoah River watershed. The model, complemented by field measurements, provides a screening tool to understand human and wildlife exposure to toxicants and pathogens associated with the incidental reuse of treated wastewater in the watershed.
