From the urban communities of Denver to the farms of Baca County, from the four corners near Cortez to the high peaks of Rocky Mountain National Park, the CoCoRaHS Network currently engages over 1,900 volunteers to measure rain, hail and snow throughout the state.

The Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) was founded in 1998 in northern Colorado. A huge flash flood, resulting from a highly localized intense rain storm that dropped over 14 inches of rain over a few neighborhoods in Fort Collins, Colorado, helped point out the role that volunteers can play to report weather events, track rainfall patterns, help scientists, and monitor water resources.

We need hundreds of more observers in Colorado . . . right in your community!  If you would like to join the network and help measure precipitation in your own backyard, please click here: Join CoCoRaHS
