Lake Cherokee (Sabine River Basin)
Lake Cherokee is located twelve miles southeast of Longview in southeastern Gregg and northeastern Rusk counties on Cherokee Bayou, a tributary of the Sabine River. The lake is owned and operated by the Cherokee Water Company to supply water for municipal, industrial, and recreational purposes. Construction on the dam began in February 1948 and was completed on November 19, 1948. The lake has a capacity of 46,700 acre-feet and a surface area of 3,987 acres at the crest of the service spillway at an elevation of 280 feet above mean sea level. The reservoir capacity is 68,700 acre-feet at the crest of the emergency spillway.
The city of Longview diverts water for municipal use. The Southwestern Power Company circulates water from the lake for condenser cooling of the steam-turbine generating units at the Knox Lee Power Plant. The drainage area above the lake is 158 square miles. According to TWDB 2003 survey, the average annual sediment filling rate at the Lake Cherokee is approximately 109 acre-feet per year after impoundment.
