C) or type in your location coordinates.

Search for or Zoom-in to your area.

Select "Delineate" button and click on the stream whose watershed you plan to analyze. Your location is sent to our L-THIA engine and the watershed of that point is calculated; then you can run L-THIA model on it to predict runoff.

To enter a specific latitude-longitude select "Lat-Lon" button below , longitude with minus sign must be within -89.00000 to -86.00000 and latitude within 37.00000 to 41.00000

Select UTM Zone16 coordinates in meters: range of X should be within 401000 to 711000 and Y within 4180000 to 4628000

Finally click Done

We are using a 10 - digit HUC watershed as the largest possible size!
