This interactive map viewer identifies potential causes of impairment and pollutant sources that need to be controlled to achieve desired phosphorous load reductions and reduce the Harmful Algal Blooms in the Western Lake Erie Basin.
iMapInvasives is an on-line, GIS-based data management system used to assist citizen scientists and natural resource professionals working to protect our natural resources from the threat of invasive species.
EDDMapS is a web-based mapping system for documenting invasive species distribution. It is fast, easy to use and doesn't require Geographic Information Systems experience. Launched in 2005 by the Center for Invasive Species and Ecosystem Health at the University of Georgia, it was originally designed as a tool for state Exotic Pest Plant Councils to develop more complete distribution data of invasive species.
GLANSIS is an inter-agency, Great Lakes-specific database for Aquatic Nonindigenous Species (ANS) information.
The Nonindigenous Aquatic Species (NAS) database is an information resource for the United States Geological Survey. Located at Gainesville, Florida, this site has been established as a central repository for spatially referenced biogeographic accounts of introduced aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, distribution maps, and general information. The data are made available for use by biologists, interagency groups, and the general public. The geographical coverage is the United States.
An interactive mapping platform that allows users to zoom in on subwatersheds and create detailed maps.
This interactive website by the Indiana State Department of Agriculture includes story map features and information on goals and actions in the Western Lake Erie Basin.
A mobile friendly view of real-time water quality data. The latest NOAA cyanobacterial index image is also available.
The extent and severity of algal blooms in the Western Lake Erie Basin (WLEB) are correlated with the amount of nutrients (nutrient load) entering the WLEB from the Maumee River. Measurements of nutrient concentrations in the Maumee River are collected by Heidelberg University and combined with USGS measurements of Maumee River flow to calculate daily nutrient loads.
The Great Lakes Observing System (GLOS) provides a HABs Data Portal in collaboration with a suite of western Lake Erie partners. In this initial stage, the page provides access to real-time data from stations around the Western Lake Erie Basin, including measurements of temperature, specific conductivity, turbidity, pH, chlorophyll and blue green algae. Upcoming enhancements will add access to grab sample data, satellite imagery, hydrodynamic model results, and meteorological observations.

This mapping webpage evaluates potential groundwater pollution areas for each Ohio county.
This mapping tool delineates groundwater resources within Ohio.
The Ohio DNR Hydrologic Atlas provides hydrological data for Ohio that is useful for environmental assessments and planning.
The PA DEP open data portal provides GIS data for drinking water, water quality, and other resources.
The Ohio Environmental Protection Agency provides an online GIS webpage containing spatial data on source water assessment and protection areas.
The Minnesota Department of Health provides GIS shapefiles on drinking water protection area, as well sampling results of manganese, radionuclides, nitrates.
The Wisconsin DNR's Surface Water Data Viewer (SWDV) is an interactive map that displays primarily statewide water-related data.
The Principal Aquifers in Lake Michigan Basin dataset contains the shallowest principal aquifers of the Lake Michigan Basin.
River segments, lakes, and estuaries designated under Section 303(d) of the Clean Water Act in Lake Michigan Basin (MI and WI).
