Interesting project. Not sure it will help the current herring crisis, but it can't hurt:
New Jersey has completed a major flooding control project at a tidal pond in Monmouth County.
The $7.4 million project at Wreck Pond involved the construction of a 600-foot concrete culvert to restore tidal flows between the Atlantic Ocean and the 73-acre waterway that straddles Spring Lake and Sea Girt, according to a release from the New Jersey Department of Environmental Protection.
The pond's natural inlet was closed in 1930s, when a pipe was added to connect with the ocean. That led to restricted tidal flows, worse tidal flooding, and poorer water quality, the release said.
The new culvert, constructed of interconnected concrete boxes supported by pilings driven into the sand, will effectively act as an inlet by using a gate to manage water levels during storm events.
The release also said that the water quality in the pond will improve since water will flush into the ocean daily. The pipe will also help fish to enter the pond and spawn.
