Who is affected and how:

• Local communities and residents near the Deerfield River: may see changes over time in river management, recreation access, land-use planning, and local tourism tied to any protective measures that follow from the study.
• Recreation users (boaters, anglers, hikers): could benefit from enhanced protections, improved facilities, or restrictions intended to preserve river values depending on study outcomes and subsequent management decisions.
• Environmental and conservation groups: gain a federal process and formal study that can support preservation and restoration actions.
• Department of the Interior / federal agencies: responsible for conducting the study, preparing the report, and any follow-up actions; they will need staff time and funding to complete the mandated work.
• Hydropower operators and other river-dependent businesses: could be affected if study findings lead to new management prescriptions or constraints on river uses, though the bill itself does not impose immediate restrictions.

Net effect: The bill starts a federal review process that can lead to stronger protections and federal involvement in river management. Immediate effects are administrative (the study and report). Material changes for users and owners would depend on study results and later decisions, and the timing depends on when funds are made available.
