Formerly known as the Lynnfield Marsh, Reedy Meadow is the largest freshwater cattail marsh in Massachusetts. It is located in the towns of Lynnfield and Wakefield. The majority of the Lynnfield portion of the meadow is owned by the Town of Lynnfield Conservation Commission and National Development. The U. S. Department of the Interior designated Reedy Meadow as a National Natural Landmark. It is the major water retention area for the Saugus River Watershed, as well as a natural wildlife refuge. Pillings Pond drains into the meadow. The best access in Lynnfield is traveling along the old railroad bed at Summer Street by Saint Paul’s Church.

Lynnfield Marsh IBA, now officially named Reedy Meadow, is an area of extensive freshwater marsh in the floodplain of the Saugus River. The system was dammed to store water for the city of Lynn. The site is surrounded by urban and suburban development. Possibly, it is the largest contiguous emergent freshwater marsh in Massachusetts. The habitat is predominantly cattail marsh with some significant invasions of Common Reed and Purple Loosestrife, but there are also areas of scrub, especially Buttonbush, swamp; an area of seasonally flooded canary-grass meadow; some areas of Tussock-sedge meadow; bordering areas of wooded Red Maple swamp; and some wooded islands and peninsulas dominated by oak-conifer forest. There are also several ponds. The marsh is surrounded by dense suburban development with a golf course forming a boundary to the west, an industrial park, and a business park on a large artificial island near the south end.
