Interpretive Programs

Visitors are welcome to walk into the park and utilize the area. Fall and winter are a wonderful time of year to take a walk through the park and when we have enough snow, snowshoeing and cross-country skiing as well as snowmobiling are a great way to get out and enjoy the park. Wildlife viewing is also a popular activity enjoyed in the park. If you are interested in interpretive programs and would like a park ranger to present a program, we are available for both on and off site presentations. If you have any questions or would like to schedule a program please call.

Natural Resources

More then half of Otter Brook Lake's 458 acres, are forested with white pine, hemlock, maple, beech, birch, and oak. The open areas are a mix of old fields, wetlands, shrub areas, and the 90 acre lake itself. These varied habitats provide for a diversity of both resident and migratory wildlife. Deer, fox, raccoons, beavers, and turkeys make their home at Otter Brook Lake year round. Waterfowl, such as canada geese, black ducks and mallards use the area to rest and feed along their migratory journey.

Natural resources are an important component to the management of Otter Brook Lake. Park rangers use an assortment of forestry techniques to improve or conserve different habitat types. Woodcock habitat improvements have been conducted as well as managing a deer yard on the property. Apple trees are planted and pruned for food production for deer, turkeys, grouse, and various other bird species. Park rangers have also studied vernal pools and other unique habitat types and have conducted amphibian surveys to ensure biodiversity and maintain a healthy ecosystem.
