National Dam Inspection Program. Warner Dam (NDI Number PA 00975, PennDER Number 58-71), Susquehanna River Basin, Tributary of Snake Creek, Susquehanna County, Pennsylvania. Phase I Inspection Report
Warner Dam is owned by William S. Newlin, Jr., and is classified as a 'Low' hazard - 'Small' size dam. The dam was found to be in fair overall condition at the time of inspection. Hydraulic/hydrologic evaluations revealed that the spillway capacity is less than the peak inflow to the impoundment during the 100-year flood. A spillway design flood (SDF) in the range of the 50-year flood to the 100-year flood is required for Warner Dam. The 100-year flood was chosen as the SDF. The spillway is therefore considered 'Inadequate.' It is recommended that the owner immediately develop remedial measures to provide adequate spillway capacity. The inspection revealed certain items of remedial work which should be performed by the owner without delay. These include: (1) Provide adequate spillway capacity; (2) Repair the spalling on the downstream face of the concrete corewall; (3) Ensure that the outlet works are operable, or develop an emergency drawdown plan; and (4) Cut all trees on the embankment at ground level. All trees with a trunk diameter greater than 3 inches should have their root systems removed. All resultant areas of erosion and cavities should be filled, graded, compacted and seeded. In addition, the following operational measures are recommended to be undertaken by the owner: (1) Develop a detailed emergency operation and warning system; (2) During periods of unusually heavy rainfall, provide around-the-clock surveillance of the dam; and (3) When warning of a storm of major proportions is given by the National Weather Service, activate the emergency operation and warning system.
