Detailed Description

Photographs show the CoSMoS forecasted extent of flooding (blue) across the western Swinomish Reservation compared to the actual extent of maximum flooding (black line) in March 2016. This helped to validate the accuracy of the USGS CoSMoS model. The projections are made by the USGS and overlaid on a 2011 photograph credited to the National Agricultural Insurance Program (public domain).
