Flood Observatory Mission Statement
The Dartmouth Flood Observatory was founded in 1993 at Dartmouth College, Hanover, NH USA and moved to the University of Colorado, INSTAAR in 2010. Its sustained, not-for-profit operation depends on grant and project support. Financial contributions may be tax-deductible.

Since late 1999, satellite data have been obtained by the Flood Observatory, processed to detect water/land boundaries, and analyzed to produce flood inundation limits in vector GIS format. DFO's Current Conditions updates this information each day into displays showing current surface water compared to the record of flooding. In 2017, we are revising the displays for global coverage. New format sample: 090E030N.
River and Reservoir Watch
DFO's River and Reservoir Watch provides experimental, fully automated satellite-based river discharge and reservoir area measurements. They are updated daily and do not require any ground-based information. However, ground-based gauging stations can test its results (blue line in example below, Site #91, Wabash River, central USA). DFO is developing an array of validated measurement sites for the Earth (click on link above or map below).
The same technology is also being used to monitor reservoir area changes (Site #2012, example below; satellite altimetry for comparison).
