National Dam Safety Program. Lake Land' or Dam (Inventory Number VA 03309) York River Basin, Caroline County, Commonwealth of Virginia. Phase I Inspection Report
Lake Land' or Dam is an earthfill dam with an embankment approximately 2,159 feet long and 28.2 feet high, and a 39.9 foot long concrete spillway. The dam, located in Caroline County, Virginia, is used to impound Lake Land' or for recreational purposes by the residents of the Lake Land' or Development Community. Lake Land' or Dam is an 'intermediate' size - 'significant' hazard dam as defined by the Recommended Guidelines for Safety Inspection of Dams. The dam and appurtenant structures appear to be in fair overall condition. Visual inspection of the dam revealed several minor deficiencies requiring further attention. A stability check of the dam is not required. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy, the 1/2 Probable Maximum Flood (1/2 PMF) was selected as the spillway design flood (SDF). The SDF was routed through the reservoir and found to reach a maximum water surface elevation 1.3 feet above the top of the dam. The spillway is capable of passing up to 25 percent of the Probable Maximum Flood or 50 percent of the SDF without overtopping the crest of the dam. Therefore, the spillway has been adjudged as inadequate, but not seriously inadequate since there is not a high hazard to loss of life downstream of the dam from large flows.
