Swans Thriving at the Res

Blog
A pair of swans and three cygnets were enjoying the waters of the Res this morning near the emergency spillway.  The female is actually perching on a rock. We've also had reports of the male trying to intimidate dogs walking on the path. Postscript:  Yesterday morning was very dramatic! The daddy swan hissed at a husky and the husky went into the water chasing him! The husky would not come out and her owner said she doesn’t normally like to swim. The swan teased her and made her swim away from the mom and babies. The dog just kept swimming and swimming after him but, of course, couldn’t catch him. Finally a man came with a canoe and paddled out to direct the husky back to shore. They all got…

May Garden Planting

Blog
Saturday May 23 was a great day for working at the Res Native Plant Habitat Garden.  Not too hot, not too cold, not too wet. We had a good turnout of about ten people and put in a lot of new plants, as well as removing invasive ones.  We successfully planted over sixty plants donated by the Arlington Land Trust this past Saturday, May 23, 2026. The varieties we added to the garden included Yarrow, Butterfly weed, Aster, Coneflower, Foxglove, and Beebalm.  We have garden work days usually on the third Saturday morning during the growing season. Come by and enjoy the experience. Johanna and Cherie - Happy gardeners at work.

Fish Talk & Walk

Blog
On May 23, Eric Harrison presented an engaging and informative talk on the Arlington Reservoir, Mill Brook, and the town’s broader network of water resources. He emphasized the role of fish within a complex aquatic ecosystem, describing the density of life in the water, the interconnected food chain, and the relationship between aquatic species and bird life. He also shared examples of local fish species and offered practical observations on fishing gear and technique in response to questions from a local angler. He highlighted encouraging progress on the Mystic, where new fish ladders have supported the restoration of herring and alewife runs as far north as Horn Pond. He suggested that a similar restoration of Mill Brook could further strengthen Arlington’s ecological resources and bring greater recognition to the town’s…

Northern Lights At The Reservoir

Astronomy, Blog, Northern Lights
Tips for catching the Northern Lights   If you’re in Arlington and love The Res, you’ve got one of the best local spots for a potential northern lights sighting, especially if you walk down near the water with its clear view to the north. Chasing aurora right here in Arlington is a lot of fun, and half the adventure is learning to read space weather like a pro. To see the lights, you need dark nights, clear skies, a strong solar wind, and a little bit of luck! The northern lights are the result of geomagnetic forces in the upper atmosphere. The solar wind helps to create the northern lights. There is a score for how strong the solar wind is, called the KP index. The higher the solar wind…

Reservoir Bird Walk – Saturday November 9, 2024 American Black Duck (Photo by Chris Floyd) About a dozen bird watchers showed up at 8 AM on a cold blustery morning of November 9 to see what could be found at and around the Arlington Reservoir.  The walk was led by local birding expert Chris Floyd. We saw quite a few land and shore birds as well as a hawk.  One find was the American Black Duck who posed on a rock for us.  Full details can be found in the following eBird links.

American Community Gardening Association Visits

Blog, Garden
The American Community Gardening Association Visits Res Wildlife Habitat Garden On Saturday, September 28, after our gardening day, seven volunteers from the Reservoir Committee welcomed a busload of visitors from the American Community Gardening Association, who were in Boston for their national conference. The association supports local networks, provides resources, and engages in food security coalitions, school gardening, urban agriculture, and environmental stewardship. We walked through the Arlington Reservoir Habitat Garden, discussing native plants and sharing seeds. The visit continued to the nearby bioswale at Hurd Field before returning to participate in a "grounding" or "earthing" activity, where one stood barefoot on the soil to connect with the Earth's negative electrical charge allowing electrons to flow. Similar to forest bathing, grounding may enhance health through stress reduction and balancing. It…
