How do I access current conditions streamflow data?

Start at (this link opens in a new window).

Step 1

Click the blue Current Conditions button.

You will get a map with colored dots that indicate current streamflow conditions (high, moderate, or low streamflows) at streamgaging stations across the nation.

Step 2

Click on your state or territory on the national map. A map will appear showing current streamflow conditions in your state.

Step 3

Click on Statewide Streamflow Table. You will get a list of gaging stations, identified by name and number, where streamflow is continually monitored. Also listed are current available data from each station. These data usually include gage height, streamflow, and a value for comparison--such as the average streamflow for that day. How do I interpret gage heights and streamflows?

Step 4

Group the Streamflow Table by Hydrologic Unit to focus on the stations in your local watershed. Click Go.

Step 5

Now, find your Hydrologic Unit Code (HUC) or watershed name. What is a HUC? Then click on individual station number(s) within your HUC to get data from that station.

For most stations, you will get a graph like the one below, which shows 7 days of current condition discharge (streamflow) data and historical data (median daily streamflows) for this station on the Cimarron River in New Mexico:

Step 6

For more data, change the default 7 days to a number up to the number of days wanted, or enter a begin and end date, and click GO to get data. Current condition streamflow data are available since October 1, 2007, and will include the entire period of record starting in late 2012 or early 2013. See system news for an announcement.
