What You'll Find at Back River

Back River is a tidal estuary that runs roughly north-south through Bourne, Massachusetts, draining into Buzzards Bay near the town line with Mashpee. The river is narrow—rarely more than a few hundred feet across—and shallow in most sections, which makes it ideal for wading and small boat fishing. The bottom is mostly sand and mud, with eelgrass beds in the lower reaches that hold baitfish and attract striped bass and summer flounder.

The river's tidal range is significant. At low tide, much of the middle and upper sections expose flats and sandbars; at high tide, water pushes well inland and opens up fishing in channels and along marsh edges. This tidal swing is the key to timing your trip. Stripers move in on the rising tide to hunt in the shallows, and flounder settle into deeper holes and channel edges as the tide falls.

Access is limited compared to larger rivers in the region, but there are a few reliable spots where you can reach the water without trespassing or paying a fee.

Key Takeaways

  • Back River is a shallow, tidal estuary best fished on the rising tide when stripers move into the flats and marsh edges.
  • The main public access point is the Bourne Town Landing on Sandwich Road, which has parking and a boat ramp suitable for small boats and kayaks.
  • Summer flounder and striped bass are the primary targets; flounder fishing peaks in July and August, while stripers are active spring through fall.
  • Wading is productive in the upper sections at mid to high tide, but watch the tide tables—falling water can strand you or make exit difficult.
  • The river is narrow and shallow, so use light tackle, small lures, and quiet presentations to avoid spooking fish in clear water.

Bourne Town Landing and Boat Access

The Bourne Town Landing on Sandwich Road (Route 130) is the main public access point for Back River. The facility has a paved boat ramp, parking for roughly 20 vehicles, and a small pier. The ramp is suitable for launching kayaks, canoes, and small center-console or skiff-style boats. Larger boats are possible but awkward, especially at low tide when the ramp's end sits in shallow water.

There is no launch fee, but parking is limited and fills quickly on weekends during summer. Arrive early or plan your trip for a weekday if you can. The landing is open year-round, though winter access can be affected by snow or ice.

From the landing, you can motor or paddle upstream into the narrower sections of the river, or downstream toward the mouth and Buzzards Bay. The downstream route is wider and deeper, making it better for larger boats. The upstream sections are shallower and more intimate—ideal for kayaks and wading.

Seasonal Patterns and Target Species

Striped bass move into Back River in April and May as water temperatures warm, and they remain active through October. Spring fishing is often best in the deeper channels and holes; as summer arrives and water warms, stripers push into the shallows on the rising tide, especially around dawn and dusk. Fall can be excellent as water cools and stripers feed aggressively before moving offshore.

Summer flounder (fluke) arrive in June and peak in July and August. They prefer the deeper holes, channel edges, and areas with structure—fallen trees, rocks, or eelgrass. Flounder are ambush predators and hold tight to cover, so focus your casts on specific spots rather than blind casting across open flats.

Bluefish show up in summer and fall, particularly in the lower river near the mouth. They are aggressive and will chase small lures and live baitfish. Weakfish are occasional visitors in summer and early fall, usually in the deeper sections.

Wading and Shore Access

Wading is productive in the upper sections of Back River, particularly around the bends and along the marsh edges where current scours deeper pockets. The bottom is soft—sand and mud—so wear wading boots with good grip. The water is often clear, which means fish can see you; wade slowly and keep your shadow off the water.

Access for wading is limited to the town landing and a few informal pull-offs along Sandwich Road, but these are not reliable and may be on private property. Stick to the town landing and ask locals or the town harbormaster about other legal shore access before exploring.

Timing is critical when wading. Plan to enter the water at mid-tide and fish the rising water as it pushes into the shallows. Avoid low tide, when you may find yourself stranded on a flat with no water deep enough to wade out of. Always check the tide table before you go, and give yourself a safety margin—start heading back before the tide peaks.

Lures, Bait, and Tackle

Back River's narrow, shallow water demands light tackle and subtle presentations. For stripers, use 1/4- to 1/2-ounce soft plastics on light jig heads, small topwater plugs, or shallow-running crankbaits. Stripers in this river are often wary of heavy lures and loud splashes. Cast parallel to the marsh edge or along channel edges, and work the lure slowly.

For flounder, live or fresh-dead baitfish work best. Mullet, mackerel, and silversides are all effective. Use a simple rig: a 2/0 to 3/0 hook on a light leader, a small sinker to keep the bait near bottom, and a rod sensitive enough to feel the flounder's take. Flounder bite softly, so set the hook quickly when you feel weight.

Live shiners and small bunker work for both stripers and bluefish. If you can catch or buy live bait, it often outperforms artificials in this river. A simple live-bait rig—hook through the nose or back, minimal weight—is all you need.

Tide Tables and Timing

Back River's fishing is entirely tide-dependent. Stripers are most active on the rising tide, when water pushes into the shallows and marsh edges. The first two hours of the flood tide are often the most productive. As the tide peaks and begins to fall, fish move back into deeper channels and holes.

Flounder, by contrast, often bite better on the falling tide, when they settle into deeper pockets and wait for baitfish to wash past. However, flounder will bite throughout the tidal cycle if you fish the right depth and location.

Check tide tables for Buzzards Bay or Bourne before each trip. The National Oceanic and Atmospheric Administration (NOAA) provides free tide predictions for the area. Plan your trip to arrive at the landing 30 minutes before the tide begins to rise, so you can launch and position yourself before the bite starts.

Hazards and Practical Considerations

Back River is shallow and narrow, which creates specific hazards. Submerged stumps, rocks, and pilings are common, especially in the upper sections. Propeller damage is a real risk if you motor at speed. Slow down and watch the water ahead, particularly at low tide when hazards are more visible.

Mosquitoes can be intense in summer, especially around the marsh edges at dawn and dusk. Bring insect repellent and consider long sleeves and pants if you are wading in the early morning or evening.

The river can get crowded on summer weekends, particularly around the town landing. If you want solitude or better fishing, plan a weekday trip or fish during the shoulder seasons—April, May, September, and October.

Frequently Asked Questions

Can I fish Back River from shore without a boat?

Yes, but access is limited. The Bourne Town Landing has a small pier and nearby wading areas, but most of the river is only accessible by boat or kayak. Wading is productive in the upper sections at mid to high tide, but you will need to launch from the town landing or find informal access along Sandwich Road (which may be private).

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

Spring (April–May) and fall (September–October) are excellent for stripers. Summer (July–August) is peak season for flounder. Winter fishing is possible but slow. If you want the most consistent action, plan a trip in May or September when water temperatures are moderate and both stripers and flounder are active.

Do I need a boat to fish Back River?

A boat or kayak gives you access to more water and deeper sections, but wading from the town landing is productive for stripers in the shallows. A kayak is ideal for this river—it is quiet, draws minimal water, and lets you reach narrow channels and marsh edges that larger boats cannot.

Is there a parking fee at the Bourne Town Landing?

No, parking is free. However, spaces are limited and fill quickly on weekends. Arrive early or fish on a weekday to ensure a spot.

What should I do if I get stranded on a flat at low tide?

Avoid this by checking the tide table and starting your wade at mid-tide, giving yourself time to exit before the water drops too far. If you do get stranded, stay calm, stay in the water to avoid overheating, and wait for the tide to return. Always tell someone where you are going and when you expect to return.
