This dam has been classified as unsafe, non-emergency by the St Louis District as a result of the application of the following criteria: (a) Spillway will not pass 50 percent of the Probable Maximum Flood without overtopping the dam; (b) Overtopping of the dam could result in failure of the dam; and (c) Dam failure significantly increases the hazard to loss of life downstream.

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.

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.
