Flow365 Monitoring Team

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

Who Are We?

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 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. 

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.

2024 Water Year Annual Flow365 Report

This year’s flow data indicates we recorded less flow days overall when we compare to the 2023 water year, but with much of the rain occurring in the first 6 months of the 2024 calendar year, many of our rivers still experienced flow on some level. Many of the sites highlighted in this report had decreased flow through our monsoon season, even with an average amount of monsoon rain. We also saw some of our more intermittent sites, like the Wentworth Bosque along the Tanque Verde Creek, began flowing with winter rains in early February 2024 and continued throughout the rest of the water year, which is very unique to this area and its connection to groundwater.

Flow365 Community Monitoring Data Dashboard

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 and have a personal site visit with our River Run Network Program Manager Lauren Knight at your new monitoring site. You will 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.
