Oak Creek Watershed Improvement Plan

The Water Quality Improvement Grant funds will be used to identify and mitigate sources of E. coli bacteria loading within the Oak Creek watershed so that this pollutant can be removed from Arizona’s “impaired” waters list. This will be accomplished in two phases.

The Oak Creek watershed comprises approximately 300,000 acres in central Arizona, and includes five major tributaries between the headwaters in Fry Canyon and the confluence with the Verde River south of Cornville. In spite of multiple efforts and funding during the last 20 years to identify and eliminate sources of fecal contamination to Oak Creek, impairment by the fecal coliform Escherichia coli (E. coli) continues to be a persistent problem, resulting in seasonal closures of recreational areas of the stream, an “Impaired” classification by the Arizona Department of Environmental Quality (ADEQ), and most recently, an “Impaired” classification of an approximately four-mile long reach of Spring Creek, a tributary of Oak Creek.

Dear Property Owner:

As you are probably aware, Oak Creek has been classified by the Arizona Department of Environmental Quality (ADEQ) as “impaired” because of a persistent problem with the fecal  coliform Escherichia coli (E. coli).

This survey is designed to obtain residents’ opinions on human behaviors that affect water 

quality. It will be used to guide projects to improve water quality in Oak Creek, and its five tributaries.
