Recreation Facilities/Activities
Northfield Brook Lake is located in a scenic area adjacent to the highly industrialized Naugatuck Valley, a region where public recreation is at a premium.  

The importance of the 208 acres of public land is evident on a warm summer weekend when people gather at the park to enjoy hiking, picnicking and other outdoor activities.

Northfield Brook Lake also has two picnic shelters which may be reserved by groups for a modest fee. Shelter reservations may be made on the internet at or by calling toll free 1-877-444-6777. The reservation assures you a dry spot for your organized functions. The park also has picnic tables, grills and horseshoe pits.

The 1.7 mile long hiking trail starts at the main recreation area parking lot, the 8 stationed self guided interpretive trail follows the brook up stream. Continue across the road and follow the trail, you will cross over a stream as it winds its way up the hillside. Along the crest of the hillside you enter a mature forest with its tall trees reaching for the sky. As you descend the steep hillside you will return to the main recreation area.

Each year the eight-acre lake is stocked with trout by the Connecticut Department of Energy and Environmental Protection. Warm water fish, including bass, are naturally found in the lake.

In addition to the these activities, special interpretive programs on the natural resources, water resources, water safety and flood control are provided by Park Rangers.

Northfield Brook Lake offers a variety of educational and recreational programs in the summer months. The programs are generally scheduled for Saturday or Sunday. These family-oriented activities range from safety programs on Water Safety to Flood Control discussions where you learn about the Corps of Engineers, its history, and take a tour of the dam. You can take a guided Nature Walk where you learn about the local wildlife, plant-life, and much more about our natural resources. Programs are open to the public. All ages are welcome; however, we do ask adults to accompany their children.

Natural Resources
The natural resources on the 208 acres of undeveloped public land at the lake are managed for recreation, forest and wildlife resources.

Corps employees and Scouts have been successful in reclaiming the large borrow area on the hillside at Northfield Brook. This reforestation not only has improved the aesthetics of the area, but also controlled the once prevalent erosion problem. Certain areas are kept open to create habitat diversity. The plant that grows along the edge of the forest and the open fields are especially beneficial to wildlife.

Wildlife is abundant in the reservoir area. White-tailed deer, beaver, red fox, raccoon, grey squirrel and cottontail rabbits either live or visit project lands. Birds spotted at Northfield Brook Lake include Canada and snow geese, wood ducks, great blue heron, osprey and American Kestrel.
