Welcome to the Arlington Reservoir website.
The Arlington Reservoir (the Res) was built in the 1870's as part of a municipal water supply system, but has served since the 1890's as a recreational area for walking, swimming, fishing and boating. A perimeter path of almost a mile is enjoyed by walkers, joggers ad bird watchers throughout the year.
The total area of the Res and its shoreline is about 65 acres. Although all of the Res and adjacent land is owned by the Town of Arlington, about half of it is located in Lexington. The Res is part of the extensive watershed that connects Arlington's Great Meadows in East Lexington to the Mystic Lakes and Mystic River via Mill Brook.
The Reservoir Committee of the Vision 2020 Environmental Task Group is a group of concerned citizens working to solve the Reservoir's problems. The Committee meets on the third Tuesday of the month in the Arlington Town Hall Annex. Anyone with an interest in the Reservoir is welcome to participate.
Financial donations to support the work at the Res can be made through the Arlington Land Trust, PO Box 492, Arlington, MA 02476, or through their website:

Wildlife Habitat Garden
The habitat garden is planted with native shrubs, grasses and wildflowers that provide shelter and food for a wide variety of wildlife, including rabbits, turtles, toads, birds, butterflies bees, dragon flies and many other species. The successful wildlife habitat garden must provide food, water, shelter and places to raise young. Native plants provide the foliage, pollen, nectar and seeds that many species need to survive. The garden is located on the main path from the parking lot on both sides of the spillway .
Inspired by an anonymous donation from an Arlington Land Trust member and subsequent contributions from many other ALT members and local residents along with support from the Conservation Commission, the Wildlife Habitat Garden came to life this spring and summer after several years of planning and design work. The garden was started in 2011 and is maintained by the Reservoir Committee, a part of Arlington's Vision 2020. Financial donations to support this work at the Reservoir can be made through the Arlington Land Trust, PO Box 492, Arlington, MA 02476, or through their .

A special debt of gratitude is due to the Arlington Department of Public Works, whose staff provided critical assistance and support in many ways, initially preparing the site and especially by installing the water pipes and spigots that helped sustain the garden through the dry spells.
