PIERRE, S.D. – (DRG News) South Dakota’s State Climatologist says that officials continue looking for people interested in helping keep track of rainfall and other moisture–as part of a volunteer network that maps precipitation. CoCoRaHS stands for the Community Collaborative Rain, Hail and Snow Network. It was started in Colorado in 1998 and now includes volunteers nationwide. South Dakota was added to the network in 2007. Each time precipitation is noted; volunteers measure it and record the information on the CoCoRaHS website. Dennis Todey says CoCoRaHS shows that precipitation levels differ from place to place and he believes that expanding the monitoring network can help producers-especially in times like the current drought conditions.

Todey says the CoCoRaHS system has expanded in the five years since South Dakota joined. He says it’s easy for people all across the state to sign up.

The mission for CoCoRaHS is to provide accurate, high-quality precipitation data for its many users and encourage volunteer weather observing. Its data is used by several organizations, including the National Weather Service, meteorologists, emergency managers, insurance adjusters, the USDA and others. To find out more, visit
