CoCoRaHS Precipation Map is proud to be a contributing member of CoCoRaHS. Our manual gauge measurements are made at 7:00am daily and reported to the CoCoRaHS website. The current reports for Gallatin County and surrounding areas are shown on the map below as well as our reported measurements for Belgrade.

Since the automated rain reports on this site are from midnight and the CoCoRaHS gauge is from 7:00am, the daily rain reports may differ due to the differing times for measurement resets (automatic gauge: midnight, CoCoRaHS gauge: 7:00am). The most common reported observation will be 0.00 in. (or 'T' for trace amounts) of precipitation due to this area receiving very little rainfall compared to the national average.

CoCoRaHS is an acronym for the Community Collaborative Rain, Hail and Snow Network. CoCoRaHS is a unique, non-profit, community-based network of volunteers of all ages and backgrounds working together to measure and map precipitation (rain, hail and snow). By using low-cost measurement tools, stressing training and education, and utilizing an interactive Web-site, their aim is to provide the highest quality data for natural resource, education and research applications. The CoCoRaHS network originated with the Colorado Climate Center at Colorado State University in 1998 thanks in part to the Fort Collins flood a year prior. In the years since, CoCoRaHS now includes thousands of volunteers nationwide.

Who uses the data that's collected and reported by us at on a daily basis? Here are just a few of our many users. The most obvious ones that come to mind are:

  1. Weather Forecasters
  2. Hydrologists
  3. Water management
  4. Researchers
  5. Agriculture
  6. Climatologists
  7. Insurance Industry
  8. Engineering
  9. Recreation
  10. NASA
  11. Fisheries
  12. The Media
  13. The Federal Emergency Management Agency (FEMA)
  14. The National Drought Mitigation Center (NDMC)
  15. Local Utilities
