If you'd like to find out how your river is doing, just go to http://waterdata.usgs.gov/nwis/rt.
rt= real time data. You will get on your monitor a page that looks like the image below. It's fun to see what other parts of the country are doing. New England is wet (blue and black dots), and across the south things look below normal (red dots).
(Note: The image below is a screenshot and is not active. It is not click-able.)
Once you get this page up on your computer using the link above, just click on your state to get to your state-specific page. You'll be able to negotiate your way from there. Each dot is a different river location.
