In 1992 the state and federal Trustees settled natural resource damage claims with the potentially responsible parties. The total recovery of damages and future oversight expenses for all the Trustees was $1,353,440. The primary issue raised by the National Oceanic and Atmospheric Administration (NOAA) regarded the potential migration of contaminants through Flint Pond to the Merrimack River.

The Trustees provided $30,000 to the United States Fish and Wildlife Service (FWS) for herring/shad restocking on the Concord and Sudbury Rivers. The Trustees have also allocated approximately $10,000 to the Massachusetts Department of Environmental Protection for the repair of the Flint Pond dam to lessen the opportunity for any residual Flint Pond contamination to reach the Merrimack River. The bulk of the money has been, and will be, spent on land acquisition for conservation purposes. Properties acquired thus far include:

• A 130-acre parcel on Dunstable Road in Tyngsborough and Dunstable, located across the road from the Charles-George Landfill. Dunstable Brook runs through the property, creating some emergent marsh and wet meadow habitat. Because of the patchiness of the habitat on this property, it is expected to provide habitat for an exceptional diversity of songbirds. It also provides habitat for upland game birds like ruffed grouse and American woodcock. The property also likely provides habitat for white-tailed deer (particularly for grazing), eastern cottontail, numerous small mammals, and hunting areas for fox and coyote. A portion of Dunstable Brook running through the property was impacted by the landfill.
  
• A 75-acre parcel on Scribner Road in Tyngsborough, located on the Dunstable town line. This property is mostly forested, and abutted to the west and north by conservation land owned by the Town of Dunstable and the Massachusetts Division of Fish and Wildlife. With the purchase of this property, a contiguous block of approximately 180 acres will be protected.

The Trustees are investigating the benefits of removing the Talbot Dam or implementing fish passage improvements at the dam, the only remaining obstacle to fish passage on the Concord River.
