Our work in the Chattahoochee River has begun in the West Atlanta Watersheds of Proctor, Sandy, and Utoy Creeks. The entire West Atlanta Watershed includes two additional watersheds that are not shown on this map, Peachtree and Nancy Creeks, however these two watersheds had a number of organizations working with them and a number of resources available to them when NWF started its project so we chose the work where there was a greater need, these three watersheds. Other organizations including our primary partner organization, the Upper Chattahoochee Riverkeeper, have been successful working in and mobilizing citizens to actions in the more affluent and resource heavy watersheds, Peachtree and Nancy, but few have had much sustainable progress in these three. Because of NWF’s grassroots, bottom up approach and sensitivity to ways to work with diverse audiences, we have not only been successful in moving citizens in these three watersheds from awareness to action, but in putting these under-served watersheds on the map. We started our work in Proctor, Utoy, and Sandy Creek because they represent the most polluted tributaries of the Hooch in the metro Atlanta area and because they are home to previously underutilized constituencies in conservation and watershed protection work. We have been working with this constituency to help them change their reality of being the most overburdened with environmental stressors and pollution and the least represented at environmental decision making tables to being a citizenry recognized as being attentive and active on issues impacting their watersheds and communities.
