The Silver State is proud to be a member of CoCoRaHS! From 13,145 ft high at Boundary Peak to only 479 ft at the Colorado River, and from Reno to Las Vegas, we're now able to measure how dry or wet the Silver State really is! Joining the network in 2007, Nevada was the westernmost state at the time to participate in CoCoRaHS in the continental U.S. Be a part of this volunteer weather watching group with your own 4-inch rain gauge--simply click Join CoCoRaHS on the menu, or contact one of the state coordinators.

Who Can Join

Anyone with an interest in weather or climate can join. We pride ourselves on having trained observers. CoCoRaHS observers provide  valuable data for monitoring, responding to, assessing, and managing extreme weather in Nevada, especially the wide-ranging impacts of drought or floods.

Training Sessions

Training is required for all observers. You may attend an online training session and/or use the online training slideshow found on the CoCoRaHS home page.  Occasionally, in-person training sessions are scheduled for community groups, schools, offices, or individuals. All trainings are open to the public. RSVPs are requested, but not required in most cases. If you're interested in training for your community, please email or and let us know of your interest and where you are located. We can't guarantee we can travel to every locale, but we'll try our best.

I Want To Join. Now What Do I Do?

As soon as you have a username and password, you many enter observations, almost immediately! It is just as important to know when it rains as when it does not rain so please don't forget to report your ZEROs.
