About Weir Hill

Trace the western shoreline of a sparkling lake or enjoy a woodsy ascent to scenic views of the Merrimack Valley.

What makes Weir Hill a special place?
We think it’s the striking vistas of both scenic Lake Cochichewick and of the broader landscape of the Merrimack Valley that will charge your imagination. Whether you prefer to wander the property’s eastern border along the lake shoreline or ascend to an overlook for a westward panorama, Weir Hill Reservation will replenish body and soul.

Follow the 0.75-mile Edgewood Farm Trail to reach the meandering shore of Lake Cochichewick, which dominates the east and south edges of this reservation. The two-mile-long lake and Weir Hill ("wire hill") are the dominant natural features in the northeast part of town and easily its most scenic. In fact, Great Pond Road was laid out on the east shore to take advantage of the views across the lake and the hill rising just beyond. Cochichewick has long served as North Andover’s drinking water supply, so public access remains limited. Hikers of the Edgewood Farm and 0.4-mile Cochichewick trails can feel fortunate as they wander, enjoying terrific water-level views. Take caution if you trek this route in winter, though, as these trails get icy!

For a quite different, but equally memorable experience, take the 0.71-mile Stevens Trail up the spine of Weir Hill to where a scenic overlook opens on the right. Hikers enjoy a broad panorama of the Merrimack Valley spreading below. On days of good visibility, you can see Mount Wachusett rising in the distance beyond Worcester, and northwest of Wachusett, New Hampshire's Mount Monadnock.

Generations of agricultural use, a history of fire, and cutting and mowing regimes have created a patchwork landscape on Weir Hill that supports ten different types of plant communities, from a 60-acre oak-hickory forest to hillside seeps, intermittent streams, and wet meadows. Several threatened state-listed and watch-listed species can be found on Weir Hill, including the white bog orchid (Habenaria dilitata), violet bush clover (Lespedeza violacea), butternut trees (Juglans nigra).

Property History

Prior to settlement, Weir Hill undoubtedly was the site of Native American activity; a 1968 archaeology survey identified a campsite at the southeast end of the reservation. It is likely that Native Americans set fire to the hill to improve the landscape for hunting, and used submerged fish weirs (woven fences with stakes) to catch alewives in Cochichewick Brook before they reached Lake Cochichewick to spawn. The reservation takes its name from these fish weirs.

In the mid 17th-century, early settlers cleared the slopes of Weir Hill for use in livestock grazing, including sheep and cattle. In the 18th and 19th centuries, dams were built along Cochichewick Brook to power lumber and grist mills, and for the past 100 years, Lake Cochichewick has provided North Andover’s main supply of drinking water (public access to the lake is not permitted).

In 1853, industrialist Moses T. Stevens married Charlotte Emeline Osgood, and over the next 30 years, Stevens’ prosperous flannel wool mill enabled them to acquire much of the land on the west shore of the lake, including Weir Hill. Here, Stevens built a country estate of more than 500 acres that included a magnificent redbrick and brownstone mansion with accompanying stables, greenhouses, and farm buildings.

Later in his life, Moses T. Stevens helped found the North Andover Country Club, which was built in 1897. The original clubhouse’s half-hidden foundation can be seen in the southeast corner of Weir Hill, right on the shore of Lake Cochichewick. At the time, members would paddle across the lake to the links to play golf and then back to the club house for dinner and dancing in the evening. In 1909, the club was moved across the lake where open farmland allowed for the development of a golf course and new clubhouse.

Property Acquisition History
Original acreage a gift, with endowment, of the Estate of Abbot Stevens in 1968. Additional land given by the Abbot Stevens Trust in 1975. Additional land purchased by MLCT in 1974 with funds donated by the Abbot and Dorothy H. Stevens Foundation and the Nathaniel and Elizabeth P. Stevens Foundation. Additional land donated in 1994 by the North Andover Improvement Society.

Programs

 While we do not currently have any programs at Weir Hill, you can explore other nearby reservations through a variety of events and activities.

Conservation and Stewardship

Ascending the 0.71-mile Stevens Trail from the parking lot, you may begin to notice char marks on trees and signs of burned underbrush. Not to worry. Trustees ecologists, along with our partners at the Massachusetts Department of Conservation and Recreation Bureau of Fire Control, Massachusetts Department of Fisheries and Wildlife, US Fish and Wildlife Service, and the North Andover Fire Department, have conducted controlled burning exercises, called “prescribed fires,” on several areas of the reservation. 



The carefully monitored fires are designed to protect and promote habitat for rare species, including plants, wildflowers, and butterflies. The burns are equally important for reducing understory and woody debris that could otherwise provide “fuel” for wildfires that burn uncontrolled. Humans have used fire at Weir Hill for many centuries. Native Americans probably burned the hill to expose good hunting grounds, full of deer and other game.

Management Planning for Our Properties
 

Since 1891, The Trustees of Reservations have worked to protect special places in Massachusetts and maintain them to the highest standards. To ensure these standards are met, a program of careful planning and sound management is essential. Comprehensive property management plans are created for each reservation and are completely updated approximately every ten years. We often work with volunteers, property users, and members of the community to carry out this planning, which typically involves several steps:
 


  • Describing in detail the site’s natural, scenic, and historical resources; identifying management issues related to the protection of those resources. 

  • Developing a detailed list of management recommendations, a work plan, and a description of financial needs for implementing the actions.

I have lived in town for a few years and took our new puppy for our first walk. There are plenty of maps posted about the property. However, none of the posted maps have an idication as to "you are here". None of the trails are marked with names either. Other than that the property is gorgeous and we plan on making it a weekly ritual

We visited here on Saturday and it was a great experience. It was the first time my wife and I had gone hiking, and can't wait to do it again. We only did one trail this time, but next time we're planning on doing them all. It was perfect for beginners like us, and there are some areas that it would be great for more experience. We recommend it 100%

My name is Morgan S.(Mike)Bragg, the now 65 y/o son of a former executive with the J.P. Stevens textile company from the mid 1930s until 1960, William J. (Bill) Bragg. Both my older brother(Spike) and I are alumni of Phillips Academy in Andover. When my parents drove me to Andover[not sure if it was for my PA interview or when I entered PA as a 13 year old "junior"(as freshamen were called)] in the Fall of 1957 they brought me with them when they visited with Abbot and Dorothy Stevens at their gorgeous old home, which I assume was the brick and stone mansion mentioned in the "History" section of your web page. I remember to this day the impressive ride through the property up to the home and the fantastic views from the home over the surrounding countryside. My four years at PA were wonderful, although I never again had the opportunity to visit Mr. & Mrs. Stevens again after that visit. Mike Bragg
