Chapel Branch Creek is a small creek draining into Lake Marion near Santee, SC. Lake Marion is an important recreational area for coastal South Carolina, and the adjacent Town of Santee receives much of its economic activity from related tourism. The creek is on the South Carolina Department of Health and Environmental Control’s (SCDHEC) list of impaired waters (2004 - 303d list) for excess nitrogen (N), phosphorus (P), chlorophyll-a, and pH. Despite being only 1600 ha, the watershed has an unusually large number of land uses with varying potential nonpoint sources of N and P: sewage effluent spraying, golf course management, highway runoff, urban and residential stormwater runoff, agriculture and some forests. Contamination of Chapel Branch Creek directly impacts the economic health of the local community. Our initial meetings with stakeholders revealed that vigorous debate has occurred for the past decade over the sources of contamination and responsibility for clean-up.
