National Dam Inspection Program. Flat Rock Dam (NDS I.D. Number PA 00896, DER I.D. Number 51-1), Delaware River Basin, Schuylkill River, Montgomery and Philadelphia Counties, Pennsylvania. Phase I Inspection Report,
Abstract
Flat Rock Dam is owned by the Commonwealth of Pennsylvania, and the pool formed is used primarily for recreational purposes. The left abutment of the dam abuts the Manayunk Canal wall owned by the City of Philadelphia. Visual inspection of the exposed sections of the dam, review of available data and simplified calculations presented in Appendix D indicate the dam is in good condition. No data other than Plate 12, Appendix E, were available for the canal wall. Calculations presented in Appendix G indicate the wall is marginally stable under assumed conditions. The results of the stability analysis are at variance with the canal wall's demonstrated performance history.
