National Program of Inspection of Non-Federal Dams, Tennessee. Woodrun Dam Number 1 & 2 (Inventory Number TN 06927 and TN 06933), Hatchie River Basin, near Rogers Springs, Hardeman County, Tennessee. Phase I Investigation Report,
Abstract
Woodrun Dams No. 1 (west dam) and No. 2 (east dam) are colinear earthen structures 885 feet and 945 feet long respectively. The impoundments of each structure are interconnected by a channel forming a single 43 acre lake. Dam No. 1 is 27.5 feet in height with a crest width of 15 feet. Its upstream and downstream slopes are 1V:2.5H and 1V:2.8H respectively. Dam No. 2 is 33.2 feet in height with a crest width of 10 feet. Its upstream and downstream slopes are 1V:2.7H and 1V:3.6H respectively. Both dams are uniform in cross section and host no deleterious vegetation. The reservoir has a drainage area of 249 acres. It is predominately wood-land with an average ground slope of approximately 14%. The downstream slope of Dam No. 1 is wet with seepage beginning approximately 20 feet below the crest extending to the toe and becoming attenuated toward the ends of the dam. The seepage area is accompanied by moderate erosion near the maximum section. A property owner has dug a narrow ditch along part of the toe to channel seepage from his land. Pooled seepage exists along much of the channel and a clear flow of approximately 1/2 gpm was observed emanating from its upstream side. Seepage also exists on the downstream slope of Dam No. 2. It extends over a large area beginning approximately 200 feet right of the principal spillway, emerging from the slope 10-15 feet below the dam crest. The dam is not as wet and eroded as Dam No. 1, indicating that seepage is not as profuse. The principal spillway consists of a 30 in. steel pipe riser and a 30 in. outlet culvert of similar construction.
