Northern Pike Fishing on Lake St. Clair

The fish nobody comes here for

Lake St. Clair is famous for two things: the densest muskellunge population in North America, and smallmouth bass big enough to win a national tournament. Pike are the third fish on a lake with only two headline acts, and the result is a solid population that gets almost no directed pressure.

That is the whole argument for this page. On a Saturday in June, the Mile Roads grass flats will be full of bass boats and muskie trollers. The delta channels behind Harsens Island will have nobody in them.

The delta is the fishery

The St. Clair Flats — the delta where the St. Clair River fans out into the lake at the north end — is the largest freshwater delta in the Great Lakes. It is a maze of channels, marsh, islands and weed beds with current running through all of it.

For pike, that is close to perfect. They are ambush predators, and current gives them a conveyor belt of food to ambush. Every island point, every bend in the North, Middle or South Channel, every weed corner where the flow breaks, holds a slack pocket with a fish in it.

Fish it deliberately. Cast into the moving water, swim the bait across into the slack, and be ready at the transition. This is a tighter, more targeted game than throwing spoons over open cabbage, and it is more productive.

Anchor Bay and the shallow flats

The northeast corner of the lake off New Baltimore and Fair Haven is the other open-water area. Six to twelve feet of water over sand and cabbage, protected by the delta islands, and the first part of the lake to warm in spring.

The method is a heavy casting spoon or a big spinnerbait worked over the weed tops. One St. Clair-specific adjustment: the water here is genuinely clear over grass, unlike the stained inner Saginaw Bay where bright colors rule. Silver, gold and natural patterns are the better choice.

Know which fish you have

You are fishing a lake with the highest muskellunge density on the continent, with tackle intended for pike. Two consequences.

First, use a leader that will hold a muskie — 100 lb test, wire or heavy fluorocarbon. A leader sized for a 28-inch pike parts on a 48-inch muskie, and you lose both the fish and the bait, and the fish swims off with hooks in it.

Second, learn to tell them apart before you put one in the box. A northern pike has light bean-shaped spots on a dark body and full scale coverage on the cheek. A muskellunge has dark bars or spots on a lighter body and scales only on the upper half of the cheek. The seasons and size rules are not the same for the two species, and “I thought it was a pike” is not a defense.

Spring in the canals

April is the overlooked window. The Salt River, the Clinton River and the canal systems around Fair Haven warm several degrees ahead of the open lake, and pike move into them early. Four to eight feet of water, fishable from the bank, weeks before anyone launches a boat on the main lake.

Winter on Anchor Bay

Anchor Bay makes the lake’s most reliable ice, and the tip-up fishery there is good. Large dead baits on quick-strike rigs, set a foot off bottom along a weed edge in 6 to 12 feet. Spread flags across depths first, then consolidate.

Quick-strike rigs are worth insisting on. They set hooks in the jaw rather than the throat, which is the difference between a pike you can release and one that will not survive.

The ice here moves

This is the part that matters most. Lake St. Clair has current running through it constantly, from the delta at the north end to the Detroit River at the southwest corner, and that current runs under the ice. It thins ice unevenly, opens pressure cracks, and — when the wind gets under a sheet — floats sections away from shore with people on them. It has happened repeatedly.

Get a current local report from someone who was out that day. Ice picks around your neck, not in the sled. A partner. A spud bar. Stay well away from the delta channel mouths and anywhere else with visible current. And do not drive a vehicle out because somebody else did.

Shallow water, no shelter

Eleven feet of average depth on a nearly round lake means every wind has fetch and there is no lee shore. A 20-knot afternoon builds a steep chop with no deep water to absorb it. Add heavy summer recreational traffic off metro Detroit and a working freighter channel through the middle, and a small boat or a kayak needs a plan, not just a forecast.

Regulations

Michigan and Ontario each manage portions of Lake St. Clair and set their own pike seasons, sizes and possession rules. They change. Read the current guide from the agency whose water you are on.
