Function: This add-on downloads stream flow information from USGS monitoring sites in the United States.

The input setting format for this add-on is:

stream_flow:sitenum
where stream_flow is the add-on name and sitenum is the USGS site number. You can lookup site numbers by state/territory below:

Choose Location... Alabama Alaska Arizona Arkansas California Colorado Connecticut Delaware Dist. of Columbia Florida Georgia Hawaii Idaho Illinois Indiana Iowa Kansas Kentucky Louisiana Maine Maryland Massachusetts Michigan Minnesota Mississippi Missouri Montana Nebraska Nevada New Hampshire New Jersey New Mexico New York North Carolina North Dakota Ohio Oklahoma Oregon Pennsylvania Puerto Rico Rhode Island South Carolina South Dakota Tennessee Texas Utah Vermont Virgin Islands Virginia Washington West Virginia Wisconsin Wyoming

The pull down menu will take you to a USGS website that lists stream monitoring sites in each state/territory, along with their site numbers (typically an 8-digit number, listed in the left column as a blue link).

Example: setting the pulldown to Virginia, we see that the site number for "RAPPAHANNOCK RIVER AT REMINGTON, VA" is 01664000. The add-on setting for Wx in this case would be:

stream_flow:01664000
You can link multiple monitoring sites into the add-on using a "+" to combine them. For instance:

stream_flow:01664000+stream_flow:02041650
would load data for "RAPPAHANNOCK RIVER AT REMINGTON, VA" and "APPOMATTOX RIVER AT MATOACA, VA" into the add-on window for a track (in order listed left to right).
