Charles River Dam (adjacent to the Museum of Science) and tidal control

The Charles River Dam, located next to the Museum of Science, controls tidal exchange between the Charles River Basin and Boston Harbor; its gates and lock influence basin water levels and can affect the timing and volume of stormwater and combined sewer discharges that reach the harbor. The dam's operation is managed as part of regional flood control and water quality measures for the Charles River and adjacent stormwater systems. The dam is a fixed infrastructure feature at the Museum of Science waterfront.
