Welcome to the Water Locator Tool

STEP 1: Where is your facility located?

Provide the information for either A or B below:

STEP 2: Which water(s) receive stormwater from my facility?

To view an on-line map of waters in the vicinity of your facility, click on the "Go To: My WATERS Mapper" button (Page will open in a new window. You must disable pop-up blocking in your web browser).

Once the new window opens, follow these directions to locate potential waters that receive stormwater from your facility:

• The map will automatically identify your location based on the information provided in Step 1.
• Use the plus (+) and minus (-) signs to zoom in or out on your location.
• Water(s) will be displayed on the map in blue. Note: if the water is impaired the water will be displayed in red.
• Click on the water to identify additional features, such as the name and hydrologic unit code.
• If the name is unavailable, you will need to consult another mapping resource, such as U.S.G.S. quadrangle maps.

Keep a list of the water(s) closest to your facility for Step 2. You should verify information obtained from EPA mapping systems by double-checking the information against local mapping resources (e.g., U.S.G.S. quadrangle maps, or other topographic maps) and/or knowledge of the property and landscape. In some cases, the closest water to your facility may not receive stormwater from your facility based on actual topographic conditions.
