Abstract

The Boyer Dam was built between 1966 and 1969 on the Susquehanna River for recreation purpose. It is in use during 120 to 150 days a year, during summer in order to create a lake known as Lake Augusta. It is then deflated for the rest of the year, espacially during flooding periods.

At the beginning, the dam was equipped with rubber membranes that were noticed to be too thin, which led to numerous failures. These membranes were inflatted with both water and air. They have been replaced between 1986 and 2012 by thicker rubber and they are filled with air.

The control chamber is located on the east bank of the river.

A lot of experience has been gained by the operators on that kind of structure. They noticed air bubbles in the fold area (near pillars) of the membranes. A possible reason could be the effect of debris, ice, rocks,... on the membrane as it lays down at the bottom of the river. Another one could be an excess of stress in that fold.
