Silt: It's Impact on the City of Roswell's Cecil Wood Water Purification Plant

Abstract

History of the Watershed. Twenty-five years ago, Big Creek watershed was almost all small farms with cultivated row crops and cattle production, with about 60% woodlands. At that time, turbidity levels were high (average year 15 NW, according to plant records), but turbidities were of colloidal nature, with a clean bottom and sand bars.
