Mystic River is a public river in Middlesex County, Massachusetts, managed by Commonwealth of Massachusetts (public / navigable water). You can fish it on a Massachusetts fishing licence; bank access is at bridge crossings, MassWildlife access points and public parks. Massachusetts riverbeds are private property up to the ordinary high-water mark except on a few federally-declared-navigable reaches, so wading or bank fishing away from a public access point needs the landowner's permission. Public access confirmed via public-trust river.

Night fishing: No statewide night-fishing closure in Massachusetts on most inland waters — check local rules for water-supply reservoirs (Quabbin, Wachusett), which have their own posted hours and access restrictions.
Boats: Most Massachusetts rivers (the Housatonic, Deerfield, Westfield, Ipswich and Concord) are waded or floated by canoe, kayak or drift boat; the Connecticut and Merrimack take larger boats in their lower, wider reaches.
Bank & bivvy camping: You can fish this river on a Massachusetts fishing licence; bank and wading access is at MassGIS OFBA-listed sites, bridge crossings and public parks — check current signage for any water, as bank ownership and access rights vary by reach.
Tackle: Statewide bass limit is usually 4 (with a closed season in spring on most waters); trout limits vary by water; pickerel and panfish are generous. Check the current MassWildlife abstracts for this specific water.
Boat ramps: 4 mapped — Boat ramp, Boat ramp, Boat ramp, Blessing of the Bay Boat Ramp.
