Degradation Description
A series of six tidegates were installed in Morris Creek (New Haven) prior to 1915 for mosquito control. The tide gates leaked a little bit, but not enough to maintain healthy tidal wetlands. The tidegates significantly reduced upstream tidal flow during the flood tide, but flapped open during the ebb tide to drain storm water off the marsh and out of the system. The entire tidegate structure has been replaced several times since the initial installation in (prior to 1885), but their purpose had remained unchanged until the completion of this project.
