Study Area
The Proctor Creek Watershed covers a 16 square mile area that includes parts of downtown and Southwest and Northwest Atlanta. The headwaters of the watershed begin in downtown, and the creek emerges above ground in the English Avenue Neighborhood, and it flows northwest for nine miles until it joins with the Chattahoochee River, the drinking water source for 70% of Metro Atlanta’s drinking water and the most heavily used water resource in Georgia (Rose 2007). Historically, residents in the watershed enjoyed Proctor Creek as a recreational resource--- as a place to play, fish, and swim. The waterway was also sacred, as a place where church baptisms were held. Connecting to a strong sense of place, watershed residents had also been active for over a century in work to protect and restore Proctor Creek from the impacts of urbanization, illegal dumping and other pollution, environmental injustices, and divestment of public resources in stormwater and wastewater infrastructure (LSBC 1978; Samuel 2017; Jelks 2020). Water quality in the creek does not support its designated use as a fishable stream (GA EPD 2020), and part of the area through which it flows has been identified as an environmental justice hotspot (GreenLaw 2012). The residents of the Proctor Creek Watershed, who are primarily Black, also experience social and economic disparities (USEPA 2021). One central neighborhood in the watershed has the lowest life expectancy in five core counties in Metropolitan Atlanta.
Eleven (11) Proctor Creek sampling sites were chosen, by USFWS based on guidance provided by other federal agencies engaged in the UWFP, to gauge the relative stream health and the aquatic fauna through citizen science techniques. The United States Environmental Protection Agency (EPA) sampled several sites in the watershed for water quality, and the U.S. Geological Survey (USGS) placed stream gages at three sites within the watershed to measure discharge in real time. After reconnaissance was conducted with EPA representatives, a subset of sampling sites were chosen based on accessibility, to ensure that sampling team members (both skilled and novice surveyors) would be able to enter and exit the stream with relative ease. The sites were also chosen to ensure that the watershed was thoroughly sampled without geographic bias toward a particular section. |
