Jesse Byrd Dam is located in Haywood County, Tennessee eleven miles northeast of Brownsville Tennessee and is an earth fill embankment 28.7 feet high and 518 feet long. The crest width is ten feet. Facilities for discharge of the reservoir include a service spillway located near the center of the dam that has an 18 inch asphalt coated corrugated metal riser with a 12 inch asphalt coated corrugated metal pipe barrel and a two foot section of 36 inch corrugated metal pipe attached to the top of the riser to serve as an antivortex baffle and debris guard. A slide gate is attached to the bottom of the riser to provide a means of draw down the lake. The emergency spillway is located in the left abutment in a natural swale that has had some shaping. The spillway has a bottom width of 60 feet and side slopes of 1V on 23H and 1V on 13H. Its depth of flow below the low point of the dam is 3.0 feet and its maximum capacity at this depth was calculated to be 337 cfs. The embankment slopes are 1V on 3H. The upstream slope has no wave protection. The downstream slope has undesirable vegetation. Jesse Byrd Dam is in the small size category and has a downstream hazard potential classification of high by the USCE and 'I' by the State of Tennessee.
