Flow Monitoring of the Rio de Flag

The Rio de Flag is Flagstaff's river. Like many rivers and streams in the Southwest, "the Rio" appears as a dry wash for most of the year. But when winter storms roll through Flag, and monsoon seasons pick up, the Rio flows through town and makes its way to San Francisco Wash, a tributary to the Little Colorado River.

We will host a citizen science data collection event in order to better understand water quality and flow of the Rio de Flag.

Contact Chelsea Silva at or (928) 213-2152 to RSVP.

Location: Meet at the south end of the Frances Short Pond (at Veit Cabin, directions available on this Google Map)

Note: Please dress for weather. Long pants and close-toed shoes recommended. Bring a water bottle. Gloves, trash bags, and trash grabbers will be available for use. Water, coffee, and light breakfast provided. More information about this event provided upon RSVP.
