Stone Building Railings: Major Success

At our October meeting, Evan Westrate announced that fencing for the Stone Building project has been fabricated and installantion is now complete. The new railings, shown in the photos to the righ, taken during construction, are gorgeous.

This project has been champrioned by Evan who announced last December that the DCR approved our public-private partnership proposal to replace the fencing by the Stone Building. The Friends have contributed $7,000 and the state $14,000 to the project. the official letter of commitment from the DCR was received last spring.

We all congratulate Evan on his tenacious work on behalf of all of us in bringing the project to a successful conclusion.


2018 Annual Summer Picnic  The Friends of Hemlock Gorge’s Annual Summer Picnic was held on a pleasant summer evening on August 7. Music was again provided by Karen Osborn and a good time was had by all.

Echo Bridge Railing Project

Echo Bridge is one of outstanding landmarks of the Metropolitan Parks System. Built in 1876, Echo Bridge was designed by the Boston Water Works (BWW) to carry the Sudbury Aqueduct over the Charles River. The largest of its seven arches is 130’ in length, which made it the second longest masonry arch in the United States. The bridge is remarkable for its graceful and handsome granite and brick design that contribute to the rugged beauty of Hemlock Gorge.

The historic cast iron railings pictured above are an integral component of the promenade over which pedestrians and bicyclists traverse daily. After 140 years, however, they are now in serious disrepair. In 2008, the MWRA installed a temporary chain link safety fence inside the historic railings to enable the bridge to remain open.

The time has come to either raise the funds to properly replicate the historic railings or to install a more permanent and attractive safety railing system inside the historic railings while leaving the old railings themselves in disrepair. Everyone prefers the former path if at all possible.

While State Rep. Ruth Balser was successful in allocating $250,000 in a past transportation bond bill for the railing project, full costs for the project far exceed that amount. In response to the fact that the MWRA cannot fund historic preservation projects decoupled from its water supply mission, a group of citizens has joined together to help raise funds to fix the historic railings, and we invite your support.

For more information, please see our website and our flyer.

Funds are being sought from multiple sources via a private/public partnership so that the expense of proper restoration is shared across a variety of stakeholders and contributors. Sources will include State funds, Newton and Needham Community Preservations funds, historic foundations, and private contributors. MWRA, the bridge owner, will be the funding recipient and will provide the engineering, contracting, and project management expertise to conduct the project. Will you join us in a pledge?

Please e-mail us your willingness to pledge to this project: at

2016 Saving the Hemlock Trees Project

Through the efforts of Bob Burke, a plan was made to treat the hemlock trees in the Reservation with an insecticide on Arbor Day, April 29. Jason Lupien of Lupient Tree Service was organizing the program to prvovide the labor at no cost, if the Friends could purchase the insecticide. See the minutes of our April, 2016 meeting (click here ).

Unexpectedly, the DCR announced that they had decided to undertake the treatment at no cost to the Friends. Ken Gooch of DCR and two USDA staff did in fact treat the trees on May 23. Brian was there to observe during the morning. He reports that they did dozens of trees from the pathway to the overlook to Echo Bridge, including some of the very tall ones near the bridge that look pretty sickly. If the treatment works, the results should be spectacular. They said they were going to spend the rest of the day treating trees and that they had plenty of supplies.

Arborist Ken Gooch of the DCR was at our June meeting to update us on the treatment of the hemlocks. At the moment the trees are in greater peril from the elongated hemlock scale than the adelgids. Lisa Barstow of the DCR updated us on the fence project, and Marti Rudi, also of the DCR, updated us on the stone building shingles. For more details read the minutes of our VERY informative June, 2016 meeting; to do so click here.

Finishing the rehabilitation of the Eliot Street Bridge in 2017

State authorities have completed reconstruction of the Eliot Street Bridge reconstruction at the southern end of Hemlock Gorge Reservation. Restoration of the meadow is proceeding. For details click here.

2018 Fall Cleanup

The Annual Fall Cleanup of Hemlock Gorge was canceled due to a nor'easter.

It was not a lovely day and everything had to be deferred.

Feast in the Falls 2018

Seana Gaherin and her volunteer committee successfully arranged the second of her Upper Falls Residents outdoor luncheons on June 23, 2017. The food was delicious and Jerry Reilly entertained us all with grandeloquent rap singing. A grand time was had by all.

The 2018 Feast will be in July.

Our 2013 Spring Cleanup  went well, though our invited guests were unable to attend. Most folks seemed to think that putting a fence like that near the new spillway should be our next project. We'll try to post some photos.

Spillway Dam Repair News

The dam is completed and the dedication was held in late November, 2012. The efforts of the Friends were recognized and President Brian Yates was an invited speaker. 

New Resource

Melissa Moody, a Girl Scout working with Site Supervisor Erica Aubin, has put in place a remarkable signage project running along the Quinobequin Road trail, downstream of Hemlock Gorge. Instead of static signposts, she has installed interactive signage with QR barcodes. Go have a look and bring your smartphone and QR barcode reader. It’s the future of nature trails, and we should plan something similar for Hemlock Gorge, perhaps with the Troop 242 Boy Scouts. Melissa's website is Very Impressive!

2013 Adelgid News from Bob Burke

  • Biggest news is that the Arboretum is planning to save some of its hemlocks using new technology.

  • "I met with Peter Del Tredici at the Arnold Arboretum and then went over to see their hemlocks. Peter had good news and bad news. The good news is that there is, indeed, a new hemlock treatment that is good for 5 years.  It involves placing a chemical substance in the soil rather than injecting it into the tree.The bad news is that at least 60 percent of a tree should be free of adelgids for this treatment to work. This can be quite expensive. He thinks we should look to saving perhaps half a dozen of the healthiest trees.

  • He also stated that 2011 was very bad for all the hemlocks because of the warm weather.  

  • Western hemlocks are more resistant than Eastern ones, but they don't do as well here because of the colder winters and drier summers.

  •  He says we need a professional tree company to determine what can be done.  He was reluctant to recommend one, but then casually said that Hartney Greymont of Needham is very reputable and one of the best.

  •  I had a look at the Hemlocks back in April or May, but have had a very bad ankle tendonitis that makes it difficult to walk up hills or sideways.   Maybe we could all go around and take a look at the trees during the cleanup in October.   The Hemlocks at Arnold Arboretum are also worth seeing since they have been treated and look fine."

Stone Building Windows: Great News

Windows are fabricated and have been installed! As soon as the prtective screens are put in front of them, we will be able to see and enjoy them--probably before 2013. Of course, we'll have to have a party to celebrate and thank the Sangiolos for their generous support of this much delayed project.

Newton Tab Editorial

Friends' activist Jerry Reilly had an editorial printed in the Newton Tab. Regrettably we do not have a link.

2012 Spring Cleanup Friends of Hemlock Gorge’s Annual Spring Cleanup took place on Saturday April 21 and was a big success. We had more than 30 volunteers on a perfectly wonderful spring day. We extend our thanks to everyone who volunteered, to the DCR staff and Site Supervisor Erica Aubin who provided support, and to Dunn-Gaherin's Restaurant who generously provided lunches for the volunteers. For a photo album of the event when available click here.

Website enhancements delayed

With regret we have to announce that modernization of our website is delayed indefinitely.

Finding the History in Hemlock Gorge Reservation

Sunday, June 22, 2017 2:00 PM

This walk took place on a gorgeous day, with about three dozen people in attendance. Everyone agreed that Hemlock Gorge is both a beautiful place to walk and the site of much historical importance as Newton's first industrial center. Old maps and photographs helped the group to visualize the mills that were located on the island and along the Charles River and to appreciate the importance of Worcester Turnpike/Route 9 to the area's commerce. The walk was expertly led by Lucy Caldwell-Stair, with whom the gourp found the site of the 1893 Echo Bridge Park amphitheater and the cave, the "Devil's Den," where Native Americans stored dried fish.


Adelgid News

Summer 2014

The woolly adelgid has now been in the reservation for some 15 years, and it is unclear how many of the hemlocks will survive.

We have moved older adelgid stories that have appeared on our web site to: Archive of adelgid news stories. We have archived the entire saga of the adelgids' appearance, our efforts to pass legislation to combat them, the release of the predator ladybugs in 2001, and follow up analyses in the Friends' Adelgid News Stories Archive. Below are some highlights and links.

  • The Arnold Arboretum's Response to the Adelgid (Winter 2005)  Click here to view the story.
  • Hemlock Woolly Adelgid Website (January 2005) The USDA Forest Service now has a website dedicated to the woolly adelgid. The site includes all the of the USDA's newsletters on the pest, pictures, and a great deal of technical information. Interestingly, the Forest Service is looking at several different control insects, not just the P. tsugae ladybugs we released. Click here to go the to US Forest Service adelgid website.

The new windows for the Stone Building, donated in 2002 and fabricated in 2008, are awaiting installation.

March 1, 2006

In early January, the Friends of Hemlock Gorge succeeded in our application for a Public-Private Partnership with the Department of Conservation and Recreation (DCR). The Friends earmarked $2500 for a new floor and other repairs to the Stone Building, and that amount will be matched by the DCR. We will post a copy of the correspondence soon. This means that our long hoped for plans to make the Stone Building a great venue for Friends' activities will soon become a reality (February 2006). The new floor will, hopefully, be followed soon by the new windows, for which funds have already been generously donated by the Sangiolo Trust. On February 23, we were notified by the DCR that they are preparing to pour the floor very soon, and that the Friends will be asked for input on design.
