The Connecticut River Watershed flows from the New Hampshire-Canada border all the way to where it meets the ocean on the Connecticut coast. Towards its southern border lies Stony Brook, one of the river’s distributaries that flows through the Mount Holyoke College campus. The entirety of the Stony Brook Watershed has only four impoundments, or dams — three of which are located here on campus. The sound of rushing water under spider bridge, grassy slopes leading to trees and flowering bushes along the edge of lower lake, the docks reaching out into upper lake; these are all quintessential parts of the Mount Holyoke campus that are possible because of the dams that transform Stony Brook into its current two-lake form.
