Weather Watchers

Rideau Valley Conservation Authority promotes a volunteer program called CoCoRaHS which stands for Community Collaborative Rain, Hail and Snow Network. It’s a non-profit network of volunteers who measure and map precipitation. This network started at the Colorado Climate Center at Colorado State University in 1998 and has expanded into Canada.

We are looking for volunteers that can record precipitation and enter the data into the CoCoRaHS website or App. Recording includes reading a gauge daily and can also include measuring snow in the winter months. Measuring locations are ideally areas that are open and not surrounded by trees or buildings as they interfere with the precipitation amounts.

CoCoRaHS is standardizing the data collected by having everyone use the same precipitation gauges. The gauge is offered at a discounted cost of $30 if you sign up on the CoCoRaHS website, however RVCA has a couple of gauges that we can give out.
