Scorton Ledge Fishing for Striped Bass

By Captain Ryan Collins


Scorton Ledge is one of the most well known fishing locations on the Cape. Almost everyone who wets a line in Cape Cod Bay has at least heard of the Ledge. So far in 2011 the Ledge has already coughed up another 50 pound bass to one fortunate angler.

If history repeats itself, those two 50 pound bass are just the tip of the iceberg. Most Cape Cod fishermen know the Ledge produces big bass. Yet the reason why bass "stack up" on the Ledge is an entirely different matter. There are a lot of theories floating around as to why bass flock to the area one day, and then are gone the next. Scorton Ledge does have a mysterious side to it.

Why is it such a productive area? Why do red tubes work so well? Why do bass stack up on the Ledge during the late summer and early fall? The list of unanswered questions continues. A general understanding of the Ledge will, however, at least improve your chances of being there when the fishing is hot. There does seem to be certain criteria to a successful Scorton fishing trip.

From what I have been told by divers, the Ledge is actually more of a hump. On a full moon low tide, the depth on top of the Ledge may be a mere 10 feet. I'm not a geologist, but it would make sense to say that the Ledge may of been formed by glaciers. Much of Cape Cod's landscape was shaped by glaciers advancing and retreating thousands of years ago. From what I've gathered, the Ledge has a muddy bottom that is strewn with large boulders. I have even marked boulders on my sonar that have risen 10 feet from the bottom. This is prime sea bass and lobster territory, and during the height of the summer, the Ledge is bombarded by lobster pots. The lobster pots, along with drastic depth changes make Scorton Ledge a tough place to fish. Add to the equation the flotilla of boats that descend on the Ledge when the fishing is hot, and you have yourself quite the challenging place to troll a tube.

The trick to beating the fleet to the bite lies in an angler's ability to predict when the bass will appear on the Ledge. It seems that the Ledge produces more consistent fishing during the early spring, and then again during late summer and early fall. Sometimes in the spring it is possible to pick a few fish off the Ledge before heading off to more productive areas. The bass don't seem to "stack" up on the Ledge as often at this time of the season. However this luxury of finding at least a fish or two on the Ledge fades as summer approaches. Last summer we did not catch a single bass on the Ledge during the month of July.

Towards the end of summer, things start improving again at Scorton. The bass' behavior seems to change as summer gives way to fall. At this time of the year, bass will often "stack up" on the Ledge. An entire school of stripers will appear out of nowhere, and remain on the Ledge for a tide, day or week at a time. This usually occurs after three or four days of a brisk onshore breeze. There are a lot of theories floating around as to why this happens. Some fishermen believe bait gets "blown" onto the Ledge. The bait in turn convinces large schools of bass to stack up at Scorton. Others believe it has something to do with bait being flushed out of Scorton Creek-which is located just to the south of the Ledge.

I believe bass congregate at the Ledge for a much different reason-to feed on the plethora of sandworms that call the Ledge home. Sandworms prefer muddy sediment, much like the Ledge's. Sea bass (not striped bass) also love to eat sandworms. Throughout the season, the Ledge is often covered by sea bass. Because sandworms are a staple part of a sea bass' diet, the presence of so many sea bass on the Ledge indicates there is a strong possibility that the Ledge is also home to thousands of sandworms.

If bass are focused on sandworms while at the Ledge, then this could explain why tube and worm rigs work so well. Fully grown sandworms can reach four feet in length. These worms are often red or orange in color-a good match for many of the most popular tubes on the market. It'd be easy to conclude that bass at the Ledge mistake tubes for big sandworms. Bass have a tendency to move closer to shore towards the end of summer and start of fall. This tendency, coupled with a brisk onshore breeze, may help to draw bass to the Ledge. The onshore wind will kick up the Ledge's muddy bottom. Waves and currents help to stir up the sediment. The constant pounding of waves and currents over the Ledge disturbs the sandworms that are usually hunkered down in the mud, making them more vulnerable to attack by large stripers.

Could the brisk onshore winds of late summer, the bass' tendency to move shallow, and a potential worm spawn be responsible for the blitzes at Scorton? I've been led to believe that most worm spawns happen during the spring, however I wouldn't be surprised if another happens during late summer on the Ledge. When spawning, mature male and female sandworms leave their muddy boroughs. These types of spawns occur on an enormous scale. Certainly it would gain the attention of any bass in the area.

If sandworms are spawning around the same time that a brisk northwest wind hits during late summer, it could help to explain why such enormous schools of bass flock to the Ledge, when just days prior not a single bass could be seen in the area. Sandworm spawns could also help explain why bass prefer a tube and worm rig at the Ledge. On most trips, the fish refuse to hit anything but a properly trolled tube.
