Yellow boy forms from iron and manganese oxide precipitating out of stream water and occurs naturally in Sewanee, TN in the outlet streams of the Lake Cheston, Lake Dimmick, and Lake O’Donnell dams. Usually yellow boy appears as a yellowish-orange to brown pigment within in the drainage streams. This ferric hydroxide precipitate can act as a blanket of pollution that is potentially harmful to aquatic flora and fauna; therefore, it has capability of destructing natural ecological processes. Due to the potential harm yellow boy has on habitats and ecological systems, the Tennessee Department of Environment and Conservation (TDEC) has forbid the construction of further man-made lakes on the plateau. This is partially due to lack of understanding of possible adverse outcomes of the pollution, which could come from run-off streams that stem from the lakes. (McGrath 2011)
