Abstract:

Based on the evlauation of the conditions as they existed on the dates of inspection August 30 and September 8, 1978 and as revealed by visual observations, the condition of Shawnee Dam is assessed to be good. No conditions were observed that would require attention at this time. A swampy area was found in the emergency spillway discharge channel which appeared to be surface runoff. This area should be periodically observed to document whether or not a seepage condition is developing. It is recommended that a formal warning system be developed to alert the downstream residents in the event of emergencies. The spillway capacity is classified to be inadequate 90 PMF according to the recommended criteria. However, the spillway is not considered to be seriously inadequate because the capacity is in excess of 50 PMF.
