Project: Upper Shadow and Shadow Lake Dam Spillway Modifications
Client: Shadow Lake Inc.
 |
Shadow Lakes, Inc. is a private lake community in the Borough of Franklin
Lakes, Bergen County. The Association owns two lakes, each created by
an earth embankment dam, namely the Upper Shadow Lake Dam, and the Shadow
Lake Dam. Based on classification reports generated by GSE on behalf of
the Lake Association and submitted and approved by the NJDEP Bureau of
Dam Safety, both of these dams have been recently classified as Class
II, Significant Hazard dams in accordance with N.J.A.C. 7:20. In order
to comply with current Dam Safety standards, GSE was recently retained
by Shadow Lake, Inc. to design the necessary spillway modifications to
the spillways presently serving both the Upper Shadow Lake Dam and Shadow
Lake Dam to meet the established spillway design flood. GSE incorporated
an innovative “labyrinth” design to allow for a reduced spillway
footprint and significant reduction in overall construction costs when
compared to more traditional designs.
