Deerfield River Wild and Scenic River Study Act of 2023

This bill directs the federal government to study whether the Deerfield River (including all its branches and major tributaries like the Green River and North River) in Massachusetts and Vermont should be designated as a Wild and Scenic River. It requires the Secretary of the Interior to complete this study within three years of funding and submit a report to Congress with the findings. The study itself is the primary action; it does not immediately protect the river but would inform future decisions about potential designation. This affects the river watershed and communities along its path by initiating a formal review process.
