The information contained on this website does not purport to offer a legal “safe harbor” from the current conflict that exists between your state laws and federal law. Power is also provided for railroad use to Amtrak and SEPTA; previously to the Pennsylvania Railroad. This is due to the flashboards at Holtwood Dam, which are designed to fail when the water surface elevation exceeds 174.2 feet.

Like the sunny day hydrograph, the PMF is purely theoretical; therefore, the starting date and time for each simulation have no effect on peak stages, discharges or travel times for the flood wave, which depend on downstream distance and elapsed time since the breach. The mixed marshy terrain of the Conejohela Valley contained rapids and small waterfalls, wetlands, and thick woods along both sides of the river within a ten-year floodplain which saw annual inundations all the way down into Maryland at the headwaters of Chesapeake Bay, and experienced catastrophic floods regularly (the meaning of a ten-year floodplain). In November 2006, the authors obtained the Federal Emergency Management Agency’s HEC-2 input data set for the Susquehanna River. Because Holtwood Dam represents the downstream study limit, a stage-discharge curve based on the hydraulic characteristics of the spillway, flashboards and powerhouse was used in lieu of an inline structure to model it. Under FERC’s Dam Safety Performance Monitoring Program, owners of dams that impound water for hydro powerhouses must evaluate facility safety under all potential failure modes. On arrival Officer Brian Liddick found that Safe Harbor Officials detained two 15 year old juveniles for trespassing onto the Power Station Property.

The FEMA cross-section elevations, which date back to the 1980s, were adjusted accordingly. Because the 104.5-foot-wide-breach at 100,000 cfs involves two or more monoliths, peak stages, discharges and travel times associated with this scenario (see Table 2) are appropriate for the preparation of inundation maps and other EAP documents.
