The bill titled "An Act relative to Great Brook State Park Trust Fund" proposes the establishment of the Great Brook State Park Trust Fund, which will be managed by the commissioner of conservation and recreation. This fund will be credited with various sources of revenue, including appropriations from the general court, public and private donations, fees from permits and licenses related to the park, and any interest earned on these funds. The commissioner is required to consult with stakeholders, such as recreational users and the Town of Carlisle, to ensure the fund meets the needs of the community.

Funds from the Great Brook State Park Trust Fund will be used to support recreational, educational, and conservation initiatives within the park, including the construction and maintenance of facilities and infrastructure improvements. Importantly, any unspent balance in the fund at the end of a fiscal year will carry over to the next year and will not revert to the General Fund, ensuring that the resources remain available for future expenditures. Additionally, the bill stipulates that expenditures from the fund must not result in a deficit at any time.
