Join the Community Precipitation Monitoring Project – It’s Easy!
Through the Community Precipitation Monitoring Project, you can contribute to community science without leaving your own backyard!
How does it work?
First, 糖心直播 (UTRCA) staff will install a simple yet sophisticated rain gauge system on your property. Each day after, you will measure daily precipitation and record the results in the Community Collaborative Rain, Hail, and Snow (CoCoRaHS) online platform.

Thousands of volunteers across participate in CoCoRaHS, with over 20 being right here in the Upper Thames River watershed. Each of these volunteers provide high quality data for natural resources, education, and research applications.
Why participate?
The data you collect locally will:
- enhance the UTRCA鈥檚 water monitoring system and fill data gaps,
- improve our understanding of significant rain events and their distribution after they occur,
- improve our understanding of climate change trends over time,
- improve our understanding of drought,
- improve our understanding of snow distribution in the winter and spring,
- calibrate and verify our hydrology and water budget models, and
- support water-related education programs.
鈥淚 think it鈥檚 a great way to participate in your town as a volunteer and provide that information for scientific research.鈥 shared Derek Ruthig from Thames Vista Farm in St. Marys.

Derek, and his good friend Frankie the donkey, care for a herd of about 50 cattle. 鈥淚 come out and go for a walk around the farm on a regular basis and it takes about 60 seconds to dump the gauge, measure it, and record it. Just that information and knowing that you鈥檙e part of a bigger program, I think it鈥檚 rewarding and worth it,鈥 he said.
We need you!
We’re looking for more volunteers to help with the CoCoRaHS project, particularly near St. Marys (Wildwood Conservation Area) and the northern part of the watershed. We provide the technology, equipment, and training to set you up for success!
Update (Aug. 28, 2024): Volunteer spots are currently full. Thank you for your interest in participating in this project!
