s and provides areas for wildlife and recreation.

Torrential rains from hurricanes in 1938, 1955 and 1968 caused water levels to rise and rivers to overflow their banks in communities across New England. The floodwaters caused millions of dollars in damage and took hundreds of lives throughout New England. Along the Charles River, the residents and properties of the lower Charles are the most seriously affected when flooding occurs.

As a result of these floods, the Corps of Engineers conducted a study that determined the best way to protect the populous lower basin of the Charles River was to construct a pumping station capable of rapidly discharging the floodwater into Boston Harbor

. The study also determined that the best way to protect the middle and upper portions of the river system from future flooding would be to protect the natural storage capacities of the wetlands.

Flood control

The lower 9 miles (14.5 km) portion of the watershed known as the "Charles River Basin" was created in 1910 with the construction of a dam across the mouth of the river. There was no dependable means of discharging river flood flows into Boston Harbor, since the dam relied on gravity flow with the sluice gates operating only at low tide. In addition, the dam effectively eliminates salt water

In 1968, congress authorized the Corps to build the new Charles River Dam

 at the mouth of the Charles in Boston. The $61 million structure was completed in 1978. Six massive pumps at the dam maintain a safe basin level by discharging river flows into the harbor. Each 3,000 horsepower diesel engine pump is cable of discharging 630,000 gallons of water per minute. The structure includes navigation locks to handle ever-increasing boat traffic. The dam is now operated and maintained by the Metropolitan District Commission of Massachusetts.

Studies by the Corps of Engineers revealed that the communities above Newton had a history of only minimal flooding. Extensive marshes, swamps and wet meadows scattered around the upper watershed were holding floodwaters and then only slowly letting them go.

In 1974 Congress authorized the "Charles River Natural Valley Storage Area," allowing for the acquisition and permanent protection of 17 scattered wetlands in the middle and upper watershed. final acquisition totaled 8103 acres (3,279.2 ha), with 3221 acres (1,303.5 ha) of land acquired in fee and 4882 acres (1,975.7 ha) in flood easement, at a project cost of $8,300,000. The Massachusetts Division of Fisheries and Wildlife manages the fish and wildlife resources in some of the Corps' fee - owned land.

Thanks to the foresight of the Corps' planners of the 1960s, increasingly valuable wetlands now provide both flood protection and open space to be enjoyed by future generations.

Preservation

The Corps of Engineers has acquired the natural valley storage areas of the Charles River to be maintained in a natural state in perpetuity.

The Charles River Natural Valley Storage flood control project was authorized by Public Law 93-251 as a "multi-purpose" project for flood control, recreation and fish and wildlife management. As a result, all land was acquired to be preserved in its natural state and to prevent any alteration of natural drainage characteristics.

The Corps is dedicated to safeguarding these natural areas as green space for flood protection, recreation, wildlife habitat and guaranteed protection of open areas. The Charles River must remain a legacy pass by this generation to all those that follow.

Recreation
