| #D025 | | How’s My Waterway | A user-friendly search tool that retrieves state-reported water quality conditions from EPA data systems for a user-defined local search area. It allows you to see if your waterway was checked for pollution, what was found and what is being done. | high |
| #D026 | | Surf Your Watershed | This tool allows one to find citizen-based groups that are working to your watershed. You may want to contact one of these groups to find out about cleanups, monitoring activities, restoration projects and other activities. | high |
| #D027 | | Watershed Central | This site has been designed to assist users to develop and put into place effective watershed programs. It includes guidance, tools and case studies to help you share information, analyze data and identify opportunities to begin or increase your efforts. | high |
| #D028 | | ATTAINS | Water Quality Assessment and TMDL Tracking. ATTAINS contains information on waters that are not supporting their designated uses. These waters are listed by the state as impaired Under CWA section 303(d). The database also tracks the status of TMDLs and actual TMDL reports. | high |
| #D029 | | MyEnvironment | For more experienced users, MyEnvironment is a search application that provides a cross-section of all environmental information for a specific location. Under the MyWater section, users can access information on all of EPA’s water programs, such as water quality assessment, drinking water and discharge permits, as well as from other sources, such as streamflow data from USGS. | high |
| #D030 | | WATERS GeoViewer | This webpage displays snapshots of EPA Office of Water program data. It depicts the status of NPDES permits for each state, summary information from the clean Watershed Needs Survey and water quality assessments. WATERS GeoViewer also contains water-related geographic themes such as 12-digit watersheds, the national stream network known as the national Hydrography Dataset and other water-related map layers. | high |
| #D031 | | Restoration and Protection Screening | This site provides technical assistance for restoration programs. It helps states consider where to invest their efforts and resources for greater likelihood of success, based on the traits of their own geographic area's environment and communities. | high |
| #D032 | | Compendium of Tools for Watershed Assessment & TMDLs (pdf) | This report contains useful information for selecting appropriate models and supports the watershed approach by summarizing available techniques that assess and predict physical, chemical and biological conditions in waterbodies. | high |
| #D033 | | NHDPlus in WATERS | The National Hydrography Database (NHD) provides a national framework for assigning reach addresses to water quality related entries, such as dischargers, drinking water supplies, streams affected by fish consumption advisories, wild and scenic rivers, assessed waters under CWA 305(b) and 303(d), designated uses and more. | high |
| #D034 | | Water Pollutant Loading Tool | The Discharge Monitoring Report (DMR) Pollutant Loading Tool is designed to help users determine who is discharging, what pollutant they are discharging and how much, and where they are discharging. The tool calculates pollutant loadings from permits, DMR data and NPDES Compliance data. | high |
