National Dam Inspection Program. Tamarack Lake Dam 'B' (NDI-PA-00746, PennDER-20-47B, SCS-PA-461B), Ohio River Basin, Mud Run, Crawford County, Pennsylvania. Phase I Inspection Report,

Abstract

Tamarack Lake is impounded by two separate dams at opposite ends of the reservoir. Tamarack Lake Dam 'B' is located at the southern end of the reservoir and Tamarack Lake Dam 'A' is located at the northern end of the reservoir. Tamarack Lake Dam 'B' is a homogeneous earth dam designed by the Soil Conservation Service (SCS), U.S. Department of Agriculture. This multi-purpose reservoir and dam is presently owned and operated by the Pennsylvania Fish Commission. The dam has a crest length of 425 feet and a maximum height of 21 feet. A 6-foot-high dike was constructed in a saddle area to the left of the emergency spillway channel. Tamarack Lake Dam 'B' is classified as a 'High' hazard-'Intermediate' size dam. The dam was found to be in good overall condition at the time of inspection. Hydraulic/hydrologic evaluations revealed that the spillways will pass the Probable Maximum Flood (PMF) without overtopping the dam. The spillways are therefore considered 'adequate.'
