The whitewater widget allows you to track and graph real-time USGS river flows right from your dashboard. This version improves speed by downloading all the data in your prefered site list on load therefore making it quicker to jump thru all your rivers quickly. It also gets fresh data every hour so you don't have to reload or change sites to see updated flow. Finally if you double click on a graph it will take you to the USGS page for that site.
You can download it for free from
