Permits & access
Permit required — see local rules.
  • MA has no closed trout season; the Upper C&R Area (Fife Brook Dam to Hoosac Tunnel trestle) is artificial-lures-only and catch-and-release — verify segment boundaries against MassWildlife
  • DAM-RELEASE SAFETY: flow is set by Fife Brook powerhouse releases and can rise fast underfoot — check Brookfield SafeWaters before wading.
