Wet-Dry (WD) mapping is a citizen-science activity to document the presence or absence of surface water.  In Arizona this mapping is conducted on the San Pedro River, Cienega Creek, the Agua Fria River, and Ash Creek on Mingus Mountain.  The first three streams occur on lands managed by the U.S. Bureau of Land Management.  Most WD mapping is conducted in the driest time of the year (in late June), showing hydrologic conditions when the stress on habitat and wildlife is at its greatest.  Alarmingly, in early July 2017, and again in late June 2018 the Agua Fria River gage (USGS/Mayer) showed no surface flow;  the previous dry-up occurred 29 years ago!  Data collected by FAFNM on the Agua Fria also suggest a drying trend.

It is through the financial support received from FAFNM members, assistance agreements with the BLM, and a generous corporate donation from Cox Conserves that FAFNM members and volunteers are able to conduct this WD mapping.

A video about Wet-Dry mapping can be viewed at: https://www.youtube.com/watch?v=tm9Nvs8VLPA.  The FAFNM program is modeled after the program established for the San Pedro River.

The National Audubon Society has created graphs of the results of our mapping of the Agua Fria River.  To see the Audubon Story Map of our Wet-Dry monitoring go to this link http://arcg.is/0yGOKC.
