Scanning the gin-clear water from the elevated platform on the stern of my skiff, I see a large shadow cruising near the drop-off from 2 into 12 feet. Carp love shallow flats adjacent to deeper water, when prevailing winds blow in warm surface water that collects against the shore and spreads out from there. The shadow is on a rambling track to move past the boat. With a little luck—and a well-placed fly—I might be into my first fish of the day.

Carp cruise with seeming deliberation that turns suddenly random at times, as they move from one pocket or depression on the flat to the next. Sometimes fish pause and mill before moving on. It’s during these brief windows that an angler has a chance to hook up with one of the hardest-fighting, longest-running, still most under-appreciated gamefish in North America.

Carp get more active as the day progresses—sunshine on their shoulders makes them happy. So, while most other fish are hugging bottom, waiting for overcast, heavy wind, or evening shadows, carp are out while the sun crests and you’re applying a layer of Australian Gold.

I anchor the skiff on a shallow hump just away from the traveling activity, not unlike a deer hunter positioning just away from an obvious main trail. The key is the deeper pocket along the trail on the flat. That’s going to stop the fish and give me a chance.

As the shadow moves closer, I see it’s a group of three fish—the smallest about 10 pounds, the largest maybe 20. The two smaller fish are golden while the largest is darker, a richer shade of brown. Just before the carp reach the pocket, I cast a burnt-orange craw bunny to the far side—the water’s too flat to risk casting nearer the fish.

As the fish reach the pocket, I hop the craw bunny a few feet and let it settle. My grip tightens as the smallest fish turns toward the fly. Take it easy. The white mouth opens and the fly disappears. Wait. At the hint of pressure, I sink the hook and press the butt of the 8-weight into my gut. The water in the depression explodes. The fish and its comrades rocket off the flat—rod bent to the cork handle, drag singing a sweet tune, 100 feet of line sizzling off into the deep, dark-blue waters.

Ten minutes and a sore forearm later, I pull the hook from my first carp of the day. In the next hours, I’ll land 5 more fish from this pocket. This is some of the most exciting fishing in freshwater.

When to Go

Throughout the Great Lakes region, carp frequent shallow water from April through September. Spring is unpredictable, with fish moving in and out of the shallows as water temperature changes with each weather pattern. The unpredictability of spring keeps carp tight-lipped at times. Cooling water in fall also means undependable fish in the shallows. So, prime time is June through mid-August, when carp on the flats are as predictable as Monday morning mail.

Good Things Happen at 70

Water temperature is the key element in site-fishing for Great Lakes carp. When water temperature reaches 70°F or above, carp move onto shallow flats.

Monitor the temperature in the shallows where the carp want to hold, not the main-lake temperature. It’s common for water temperatures to be in the high 50°F or low 60°F range on the main lake, while they reach the mid- to high 70°F range in the shallows.

Carp move into the shallows because they like the warmth, to feed, and to spawn. In the morning it’s common to see fish move up on a flat and then immediately return to deeper water. As the day progresses and the water warms to that magic 70°F mark, fish cruise more slowly, often pausing for minutes to mill, especially in deeper pockets on a flat.

At times fish also lay up and sun in the warmest pockets or against the shoreline. It’s not unusual to find dozens to hundreds of fish lazing around in these areas on a nice afternoon. Cloudy, rainy weather sends the fish deep, until conditions change.

Choosing a Location

Bays with warm water at times hold so many fish that beginning carp anglers, upon first seeing the moving black mass, assume they’re in for a back-breaking day of angling bliss. They often end the day disappointed. Fish in back bays often are only interested in soaking up warmth. They can also be very spooky.

By comparison, prominent main-lake points offer protection, and the adjacent protected areas seem to be better feeding places for the carp. I look for points with pockets that offer food, warmth, and quick access to deep water. On the Great Lakes, such points may encompass several miles of water.

These large points gather warm water with various wind directions. If the wind’s from the west it blows warm surface water onto west-facing shores. Fish quickly move there. And if the wind switches, the fish move again. Small islands can also be good. They always have an onshore wind on at least one portion of the island.
