Be part of our community science effort and help track the flow of Tucson's creeks and rivers!



Read our 2023 Annual Flow Report

In the 2023 water year, Tucson received 10.07” of rain (NOAA) compared to our 11.92” average; receiving more of that rain in the winter/spring of 2023. Tucson experienced the hottest monsoon season on record, with an average of 89.8° and a fairly dry monsoon season with only 4.73” of rainfall compared to an average monsoon season of 5.69” rainfall. With the data we’ve compiled from the 2023 water year, we saw record days of flow along parts of the Rillito and Agua Caliente in the springtime, due to abundant winter rainfall and snowpack.

About the Flow365 Monitoring Program

Flow365 Monitors are volunteers who track the status of flow in our creeks and rivers year round. When they monitor, they also collect observations on the plants and animals in Tucson’s local riparian habitats. This one-of-a-kind data is helping us restore Tucson’s heritage of flowing creeks and rivers, adapt to climate change, and helping us prepare for a growing population that places higher demands on our regional and local water sources. In both the near and distant future, Flow365 data will help the people of Tucson protect our water, riparian habitats, and the people, plants and animals of the Sonoran Desert. Sign up to be a flow monitor here.


Why Collect This Data?

While county agencies have flow gauges at some points across Tucson to be able to alert the public about flooding, the data our Flow365 volunteers have been collecting since 2016 paints a more complete picture by recording gentler flows and capturing how flow starts and stops at different times of year. This data is critical to helping us understand how our desert rivers respond to changes in precipitation and groundwater levels. It also helps us determine the impact of collective conservation actions on creek flows, as we strive towards our long-term goal of restoring Tucson’s heritage of flowing creeks and rivers.

How Do I Volunteer?

Our Flow365 monitors are in the field collecting flow data at least once a month, but often weekly or even daily during periods of changing flow. To join this incredible group of volunteers, sign up for the River Run Network to be the first to hear about the next Flow365 Monitoring Training! There’s no scientific background necessary to join.

As a Flow365 Monitor, you’ll get the chance to meet other volunteers at our two hour training session, have a personal site visit with River Run Network Program Manager Lauren Monheim, at your new monitoring site, and commit to one year of monitoring flow at your site. You’ll also receive monthly updates from other monitoring sites, weather and flow forecasts for Tucson, and learn about other river restoration events and advocacy opportunities happening in our community.
