A Spring Expedition to Sheep Pond, Brewster

by Ryan Collins

There's something magical about spring on Cape Cod. While the air still carries winter's chill, life beneath the surface of the Cape's freshwater ponds is stirring. It's that special time of year when Massachusetts' stocking trucks make their rounds across the Cape, releasing rainbow trout, brown trout, brook trout, and even tiger trout into many of Cape Cod's glacial kettle ponds. And one pond in particular stands out among the rest - not just on Cape Cod, but across the entire state.

Sheep Pond: A Glacial Marvel

Sheep Pond in Brewster isn't just another body of water; it's a window into Cape Cod's ancient past. Carved by massive glaciers some 15,000 to 12,000 years ago during the last ice age, this kettle pond plunges to depths of over 50 feet. When you visit on a bright, sunny day, the contrast is striking - turquoise, sandy shallows along the edges that suddenly plummet into a deep, dark blue abyss, like a giant eye staring up from the landscape.

The pond's edges mirror its depths, with steep cliffs and vertical shorelines plunging straight down into the water. If you could somehow drain this natural wonder, the massive hole left behind would be a testament to the incredible forces that shaped Cape Cod's distinctive geography. Once part of the massive Laurentide Ice Sheet that covered much of North America, these kettle holes formed when enormous chunks of ice broke off, became buried in sediment, and eventually melted, leaving behind these characteristic deep depressions that filled with groundwater.

During the maximum extent of the recent glaciation, about 15,000 to 12,000 years ago the ice sheet divided into two lobes that flowed around present-day Pipestone National Monument (green star), forming the Coteau des Prairies.

The Call of Spring Fishing

After battling a nasty bout of flu that knocked our entire family down (with special recognition to my wife Lauren who somehow kept everything together while caring for both a sick baby and a bedridden husband), I finally found a window in our family schedule to escape for a few hours of fishing. My destination? The legendary Sheep Pond.

As I pulled into the Fisherman's Landing parking lot around 4:30 PM, I was greeted by the sight of several anglers already trying their luck. Three spin fishermen were working a cove to the east, while a fly fisherman cast his line from the beach northwest of the boat ramp. The pristine launch area offers plenty of room for boats and trailers, though a strict horsepower limit is enforced - not a concern for my kayak with its "zero horsepower" motor.

What happened next filled me with both hope and a touch of concern. In the brief time it took me to rig up and launch my kayak, the fly fisherman landed three trout right from the beach. Meanwhile, the spin fishermen remained fishless. As a spin angler myself that day, this observation planted a small seed of doubt that would grow throughout my adventure...[click to continue reading...]

I'm fortunate to have grown up on the beach, and I've been fishing since kindergarten. I have great family, friends and fishing experiences to be thankful for. Just being out there is enough-catching fish is just a bonus!


  • A beautiful place for fishing! I have seen many fly fisherman catch off the beach in the early spring as well.
