Merrimack River Valley and Squan-a-Tissit TU chapters are engaged in water quality monitoring of the Witches Spring Brook Wild Brook Trout Management area in Hollis, NH. MRV Chapter Director Dave Parry is our project coordinator and is assisted by volunteers from both chapters. The project is part of the Volunteer River Assessment Program of the New Hampshire Department of Environmental Services. This study will provide information vital to the protection of this natural trout habitat. With various developments in the vicinity of Witches Brook, this study is crucial to ensure that the quality of this natural resource remains undisturbed. Witches Spring Brook is considered one of the most prolific Wild Brook Trout water in southern New Hampshire. It also feeds the aquifer to the Pennichuck water supply, providing drinking water for Nashua.
