In page Salem Beverly Waterway Canal:

"

Chapter 700 of the Acts of 1913 created the Salem and Beverly Water Supply Board and gave it the right to divert Ipswich River flows over 20 million gallons per day, up to 2500 million gallons per year, in December through May, at a certain location in Topsfield (approximately the mouth of the canal).[1] In 1917 a canal was excavated from the Ipswich River through Wenham Swamp to a pumping station in Wenham, where it was pumped up to nearby Wenham Lake, a reservoir. The board declined construction of artificial impoundments on the river or canal as unfeasible.[2] In fact, in times of high water, three channels in the bank of the modern canal allow water to flow freely into or out of the swamp, which is part of the Ipswich River wetlands.
