MetadataShow full item record
Lake Allatoona is an 11,862 acre impoundment of the Etowah River in northwest Georgia, lying along the southern tail of the Blue Ridge Mountains, only 30 miles northwest of Atlanta. The impoundment has been designated for flood control, hydropower, navigation, drinking water supply, fish and wildlife, and recreation. The lake first reached full pool level in 1950. Since that time, the southern part of Allatoona's watershed has developed rapidly as suburban Atlanta has expanded northward and initial surveys by the Georgia Environmental Protection Division suggested that the lake may be approaching a eutrophic state. Intensive sampling of Lake Allatoona was initiated in May of 1992 as part of a Clean Lakes Phase I - Diagnostic/Feasibility Study. Water quality data collected during the first several months of this study are examined here to assess the trophic status of Lake Allatoona.
