Principal Flood Problems
The major floods in this area are usually the result of a heavy snowfall followed by a sudden warm rain. A freeze on top of the snow just before the warm rain can further complicate matters by causing very rapid runoff conditions. The chief sources of flooding in Jackson County are Rogue River, Bear Creek, Ashland Creek, and Applegate River.
In 1861, there was major flooding in the county. The extent of this flood on Rogue River is indicated in the report by the USACE. The most dramatic flood in the recent past occurred along Rogue River in December 1964. Two of the areas receiving heavy damage by Rogue River in the 1964 flood were the areas around the City of Rogue River and the City of Shady Cove. Floodwaters reached depths of more than 4 feet in some structures. default Read more...
Changes since last mapping
The countywide Digital Flood Insurance Rate Map (DFIRM) conversion for Jackson County consisted of three major efforts:
1) New detailed studies of Daisy, Elk, Griffin, Horn, Jackson, and Mingus Creeks within the City of Central Point;
2) The digital conversion of effective floodplain mapping throughout the County. The digital conversion included the redelineation of effective floodplain hazard areas using newly obtained topographic data within the Cities of Ashland, Central Point, Medford, Phoenix, Rogue River, and Shady Cove; and
3) The straight digital conversion, or capture, of flood hazards in areas without new topographic data. As part of the digitization process minor modifications were made to floodplain boundaries to improve mapping accuracy and alignment based on comparison to recent aerial photography.
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.
