History

The stream was named in December 1849 by the Gregg Party. Myth has it that the leader of the party, in apparent anger with fellow companions over latitude positioning, coined the term when comparing the experience of the difficult exchange between his peers.

At the 2000 census, Mad River constituted a census county division (CCD). The population was 838 at the 2000 census. Most of the former CCD is covered by the Six Rivers National Forest and the Shasta-Trinity National Forest. Mad River itself is near the western extent of Ruth Lake, the major water reservoir for the populated area around Humboldt Bay within Humboldt County located to the northwest.

Communities within the former CCD

Most of the communities that encompass the former Mad River CCD are off main highways and at least 100 miles (160 km) from a major city. The area code for most of the region is 707, because phone service comes from larger communities in Humboldt County, such as Bridgeville or Garberville.
