Arkabutla Dam is a high hazard potential dam located in Desoto County, Mississippi with portions of the lake extending into Tate County, Mississippi. The dam is located on the Coldwater River, a tributary of the Tallahatchie River, and it stores floodwater to provide flood damage reduction in the Yazoo River Basin. The dam is located approximately 4.25 miles north of Arkabutla, Mississippi and approximately 35 miles south of Memphis, Tennessee. The project is authorized by the Flood Control Act of 1928, as amended by the Flood Control Acts of 1936 and 1938. The Flood Control Act of 1936 authorized a plan of improvement for control of headwater flooding in the Yazoo River Basin and the Flood Control Act of 1939 authorized construction of the project under the Flood Control Mississippi River and Tributaries appropriation. Construction of the project began in August 1940 and was completed in June 1943. The reservoir at Arkabutla was constructed as part of the Yazoo River Basin Headwater Project. The authorized project purposes include flood control and recreation.   The project consists of an embankment dam, abutment dikes, outlet works, spillway, and closure dikes. The project features are founded on alluvial deposits composed of clay and sand. The total length of the dam including the abutment dikes is 10,700 feet. The maximum height above the valley floor is 85 feet. The current outlet works consists of a three-gated reinforced concrete intake tower, single reinforced concrete conduit, reinforced concrete stilling basin, and outlet channel. A service bridge connects the intake tower with the crown of the main embankment and allows access from embankment to the intake structure operating floor. The spillway is an uncontrolled overflow type, in a natural saddle about 3,000 feet north of the dam. The spillway comprises a reinforced concrete approach apron, weir, chute, stilling basin, and riprap lined outlet channel. The two small closure dikes are located northwest of the spillway and have a total length of approximately 1,300 feet and a maximum height of 35 feet. Based on the 2023 Existing Condition Risk Assessment, Arkabutla Dam is currently categorized as a Dam Safety Action Classification (DSAC) 1. The primary risk driving potential failure modes (PFMs) of Backward Erosion Piping (BEP) into the outlet works drainage (PFM 8) and into the conduit were identified (PFM 10). An unfi…
