What the Back River offers and when to fish it

The Back River is a tidal estuary in the Boston area that holds striped bass, shad, and seasonal runs of other species. It flows through Weymouth and Hingham before emptying into the harbor, and access points exist along its length, though some require parking arrangements or permission. The river responds to tide more than rainfall — high tide pushes saltwater fish upstream, and low tide concentrates them in deeper pools. Spring (April through June) brings shad runs and schoolie stripers; summer holds larger stripers in deeper sections; fall sees aggressive feeding as fish prepare to leave.

The Back River is narrow and shallow in most places, which makes it different from open-water harbor fishing. You will be casting to structure — pilings, marsh edges, and current breaks — rather than working open flats. The river is also heavily developed, so access is more limited than on rural rivers. Parking and launch options matter more here than on less-populated waters.

Key Takeaways

  • The Back River holds striped bass year-round and shad in spring, with best fishing on moving tides when saltwater fish push upstream.
  • Access is limited to a few public parking areas and private launches; confirm parking rules before you go, as some lots are permit-only or have time restrictions.
  • Spring (April–June) is peak season for shad and schoolie stripers; summer offers larger bass in deeper holes; fall brings aggressive feeding.
  • Regulations follow Massachusetts saltwater rules: striped bass minimum 19 inches, one fish per day for recreational anglers; shad season runs April through May.
  • The river is tidal and narrow, so fish structure like pilings and marsh edges rather than open water, and plan your trip around tide timing.

Access points and parking

The most reliable public access is at the Weymouth Landing area, where a boat ramp and parking lot serve the lower river. Parking is free but limited, and the lot fills quickly on weekends. Arrive early or plan for a weekday trip if you want a may provide spot. The ramp itself is in decent condition but can be crowded during spring shad season.

Hingham also has a public landing on the Back River, though it is smaller and less developed than Weymouth. Parking is street-level and limited. Some anglers fish from shore along the marsh edges in both towns, but access is often blocked by private property or posted land. Always check for signs before crossing onto any bank.

If you have a kayak or small skiff, you can launch from either public ramp and fish upstream into narrower sections where fewer people venture. The river is shallow — expect 4 to 8 feet in the main channel and 2 to 4 feet along the edges — so a shallow-draft boat or kayak is an advantage.

Species, seasons, and what to expect

Striped bass are present year-round but most active April through November. Spring and fall offer the most aggressive feeding. Summer stripers tend to hold in the deepest holes and are less predictable. Fish the edges of the channel on moving tides, especially the last two hours of the incoming tide when baitfish are pushed into the river. Schoolies (fish under 25 inches) are common; larger fish are possible but less frequent.

Shad run the Back River in April and May. They move upstream on high tide to spawn in freshwater sections. Fish the deeper pools and current breaks with small shad lures or spoons. The run is short — usually four to six weeks — so timing matters. Check with local tackle shops in late March to learn when the run is starting.

Bluefish appear in summer and fall, usually in the lower river near the harbor mouth. They are aggressive and will take larger lures and live baitfish. Mackerel and herring also move through seasonally but are less reliable targets for rod-and-reel anglers.

Tides, currents, and timing your trip

The Back River is entirely tidal, so water level and current speed change dramatically over six hours. High tide pushes saltwater fish upstream and covers shallow flats; low tide concentrates fish in deeper channels and makes wading possible in some areas. Most anglers fish the last two hours of incoming tide and the first two hours of outgoing tide, when current is moving but not so fast that casting is difficult.

Check tide tables for Boston Harbor before you go — the Back River follows Boston's tide schedule. Websites like NOAA Tides and Currents or local fishing apps show exact times. Plan to arrive 30 to 45 minutes before the tide turn you want to fish, so you are in position when the bite begins.

Water temperature also matters. In spring, the river warms slowly, and shad and stripers move in as water reaches the mid-50s. By July, water can be warm and murky, which slows daytime fishing. Fall cooling triggers aggressive feeding again.

Regulations and licensing

Massachusetts saltwater fishing requires a recreational marine fishing license if you are 16 or older. You can purchase it online through the Massachusetts Division of Marine Fisheries website or at most tackle shops. It costs a small fee and is valid for one year from the date of purchase.

Striped bass have a minimum size of 19 inches and a daily limit of one fish per person. Catch-and-release is allowed and encouraged if you want to fish more than once. Shad season runs April 1 through May 31, with a limit of five fish per day. Bluefish have a 12-inch minimum and a 10-fish daily limit.

Regulations change periodically, so check the Massachusetts Division of Marine Fisheries website or call their hotline before your trip. Tackle shops in Weymouth and Hingham also post current rules and can answer questions about recent changes.

Tackle, lures, and bait

For striped bass, use medium spinning or casting rods (6 to 7 feet) with 10- to 15-pound braided line. Shad lures, small swimbaits, and topwater plugs work well in spring and fall. In summer, switch to deeper-running plugs or live baitfish (mackerel, herring, or eels) fished near the bottom in deeper holes.

Shad fishing calls for lighter tackle — a 6-foot spinning rod with 8-pound line and small spoons or shad-pattern lures. Cast upstream and let the lure drift with the current, then retrieve slowly. Shad are not aggressive strikers, so feel for a gentle tug rather than waiting for a hard hit.

Live bait — mackerel, herring, or eels — works year-round for stripers and bluefish. Fish it under a float in shallow areas or on the bottom in deeper sections. Local tackle shops in Weymouth carry live bait during peak seasons and can recommend what is working that week.

Common mistakes and how to avoid them

The most common mistake is fishing slack water (the hour around high or low tide when current stops). Fish are less active and lures are harder to work. Plan to fish the moving-tide windows instead, even if it means a less convenient time.

Another mistake is ignoring the tide schedule and showing up at random times. The Back River is small and tidal, so timing is everything. Spend five minutes checking tide tables before you leave home.

Anglers also often fish the main channel when the edges are more productive. The marsh edges, pilings, and current breaks along the sides of the river hold more fish than open water. Cast to structure, not open space.

Frequently Asked Questions

Can I fish the Back River from shore?

Yes, but access is limited. The marsh edges and some pilings are fishable from shore in Weymouth and Hingham, but most of the bank is private property. Check for posted signs before crossing onto any land. Wading is possible at low tide in shallow areas, but wear waders and watch for soft mud.

What is the best time of year to fish the Back River?

April through June is peak season for shad and schoolie stripers. September through November offers aggressive stripers as they feed before leaving for winter. Summer can be slow during the day but improves at dawn and dusk. Winter fishing is possible but less predictable.

Do I need a boat to fish the Back River?

No. Shore fishing and wading are possible, but a kayak or small boat gives you access to more water and deeper sections where larger fish hold. If you only have access to shore, focus on the Weymouth Landing area and the marsh edges at high tide.

How far upstream can I fish?

The river is tidal for several miles inland. Saltwater fish (stripers and shad) move upstream on high tide but are less common above the freshwater line. Most productive fishing is in the lower river between Weymouth and Hingham, where tidal influence is strongest.

What tackle shops are near the Back River?

Weymouth and Hingham both have local shops that carry saltwater tackle, live bait, and current fishing reports. Calling ahead to ask what is working that week saves time and improves your chances. Shops also sell licenses and can answer questions about regulations and access.
