Book excerpt: The dam is located in the southeastern portion of Iron County, Missouri. The dam forms an industrial water supply lake. The inspection team observed no conditions at the dam which require immediate remedial action. The erosion protection on the upstream slope appears adequate for this dam and the few small trees in the emergency spillway outlet channel are considered a minor deficiency which should be corrected.

This book was released on 1981 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spring Lake Dam is an earthfill structure approximately 21 feet high and 400 feet long at the crest. The appurtenant works consist of a drop-inlet pipe principal spillway and a trapezoidal channel cut into natural ground at the left abutment which acts as an emergency spillway. Our inspection and evaluation indicates that the spillway has not met the criteria set forth in the guidelines for a small size dam in the high hazard potential category. This structure has the capability to hold and pass approximately 40 percent of the Probable Maximum Flood (PMF) before overtopping. The dam appeared to be in fair condition. Deficiencies visually observed by the inspection team were: (1) a row of trees (approximately 8) along the upstream face of the dam; (2) a significant potential for restriction to flow into the principal spillway intake; (3) some minor erosion on the downstream face of the dam; (4) the emergency spillway channel is partially obstructed by six steel drums and a fence; and (5) minor seepage into the principal spillway conduit from within the embankment.

Krazynski and published by . This book was released on 1980 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potosi Lake Dam is an earth dam constructed for recreational purposes. The main spillway is a 3-ft dia corrugated metal pipe (CMP), or culvert, which discharges into an unlined earth channel. A 2-ft dia CMP serves as the auxiliary spillway and discharges into the same channel. A siphon (12-in. dia steel pipe) crosses the dam at about the midpoint. It crosses under the road and rests on the downstream slope. It discharges at the dam toe. The inspection and evaluation indicate that the dam is in generally poor condition. Specific deficiencies that were noted are inadequate spillway capacity, the high potential for spillway blockage, the dense growth of large trees and brush on the downstream slope and along the upstream crest, and lack of maintenance and periodic inspections. Hydrologic/Hydraulic studies indicate that the 10 percent probability-of-occurrence event (10-yr flood) will cause overtopping of the dam. These analyses also indicate that the dam will be overtopped for a hydrologic event which produces greater than eight percent of the Probable Maximum Flood.

Berggreen and published by . This book was released on 1980 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pierce Lake Dam, Missouri Inventory Number 30999, was inspected. This dam is classified as small due to its 37 ft height and storage capacity of 681 ac-ft. A small dam is one which is less than 40 ft in height and impounds less than 1000 ac-ft of storage. The St. Louis District, Corps of Engineers, has classified this dam high hazard; we concur with this classification. The estimated damage zone, as determined by the St. Louis District, Corps of Engineers, extends approximately five miles downstream. The community of Richwoods and several other occupied structures are located within the estimated damage zone. The inspection and evaluation indicate that the dam is in generally poor condition. Specific deficiencies that were noted are insufficient spillway capacity, very steep downstream slope, high erodibility of the embankment materials and lack of maintenance and periodic inspections. Also deemed as a deficiency is the lack of any stability or seepage analyses.
