Principal Flood Problems
Riverine flooding in Curry County usually occurs during the months of November through February. Minor flooding occurs annually in some areas, but produces very little damage. The major damaging floods are the result of winter storms producing a sustained intense rainfall which, when combine with higher than normal tides, increase the damaging effects in the lower reaches of the rivers. In the Rogue River Basin, this intense rainfall is sometimes augmented by snow melt in the Cascade Mountains. Severe flooding occurs at about 10-year intervals, usually resulting from several days of sustained heavy rainfall and is sometimes augmented by snow melt in the Cascade Mountain Range. Flooding lasts for 2 to 3 days with peak stages lasting for only a few hours. Ocean flooding is the result of higher than normal sea levels resulting from storms or a seismic disturbance on the ocean floor. Storms during the months of November through February produce the storm surge and wind generated waves which combine with the astronomical tide to cause the most frequent and serious flooding. Seismic sea waves or tsunamis, which can occur at any time during the year, are the most destructive type of ocean flooding. Physical characteristics of the continental shelf and the shoreline affect all types of waves, focusing wave energy at some locations and dissipating energy in other areas.
Countywide update from previous floodplain maps
As part of the countywide update, floodplain boundaries were digitized from the effective FIRM and Floodway panels. USGS topographic maps and aerial photography were used to adjust floodplain and floodway boundaries where appropriate. No new detailed studies were undertaken for this project.
Current products to download -
A "KML" is a file that can be downloaded and opened directly in Google Earth, ArcGIS Explorer and other viewing software available on the Internet. The KML below is for the Special Flood Hazard Area (SFHA), also known as the "100-year" flood.

A Flood Insurance Study (FIS) is the publication developed in conjunction with the Flood Insurance Rate Map (FIRM) and discusses the engineering methods used to develop the FIRMs. The study also contains flood profiles for studied flooding sources and can be used to determine Base Flood Elevations for some areas.
