Drought Impacts Lessened But Still Severe in Riparian Areas
In 2016, Pima Association of Governments worked with CWP volunteers to map the June flows in the Pima County Preserve and found improvement in perennial flow extent after several years of record lows. The BLM coordinated to map flows with volunteers the same week.
The County Preserve is at the downstream end (northern end) of the watershed near Vail. In the Preserve in June 2015, only 9% of Cienega Creek within the 9 mile segment that was once considered perennial was flowing, a record low. This year, creek flows improved to 20%. Long-term drought impacts were still apparent, as Cienega Creek has not recovered above pre-drought flow levels. Davidson Canyon also saw improvement, with its first pre-monsoon flows since 2012! Drought impacts have lessened but are still severe in riparian areas.
