Current FEMA Flood Insurance Rate Maps (FIRM'S) for the Unincorporated areas of Colusa County are available for download from the list below.  There are two versions of the maps available, High Quality versions which are 300 dpi greyscale PDF files, they are very large files, but they are of excellent quality.  The Optimized versions are simply compressed versions of the High Quality version, which are much smaller in size, but due to the compression, the quality of the file is not quite as good as the High Quality versions.  If you have a slow internet connection, it is recommended that you download the Optimized versions of the files.
