How to find a waterbody on the state map
- Select the waterbody of interest from the scroll down menus in
the 303(d) database.
- Click on the record ID.
- Note the LLID. The LLID is a unique identifier for each
waterbody in the state. It uses the latitude and longitude at the
mouth of the stream to identify the stream.
- The LLID can be converted to latitude and longitude (in decimal
degrees) by adding decimal points as follows:
- Type the latitude and longitude into the Latitude Longitude Identification Application.
- You can then identify the stream by clicking on the highlighted
point. You can use the identify tool to identify surrounding
waterbodies. You can also add such features as cities and counties
to the map.
- Please note: Some waterbodies in the state are not yet
assigned LLIDs. These waterbodies appear in the 303(d) database with
artificial LLIDs such as "1111111111112". These waterbodies will not
appear in the LLID Application map.
