Phase I Inspection Report written by Rudolph Wrubel and published by . This book was released on 1980 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations and past operational performance, Cranes Lake Dam, initially listed as a 'high' hazard potential structure, but reduced to a 'significant' hazard potential structure as a result of this inspection is judged to be in good overall condition. The dam's spillway is considered inadequate because a flow equivalent to 86 percent of the Spillway Design Flood - SDF - would cause the dam to be overtopped. (The SDF, in this instance, is one half of the Probable Maximum Flood).
