Fish species in Big McNeil Slough

Big McNeil Slough is a reservoir in Phillips County, Montana.

No reliable acreage is listed for Big McNeil Slough, so begin with visible cover and the first clear change in depth.

Fish and Baits

Fish listed for Big McNeil Slough include Black Bullhead, Common Carp, Golden Shiner, Northern Pike, Pumpkinseed, and Yellow Perch.

Along the clean side of the old channel, keep a small jig tipped with a worm or minnow close to bottom on a shelf for yellow perch.

Across the shallow corner of a small island, cover weeds, shallow points, and flat edges with a spoon or sturdy minnow lure for northern pike.

Around the current seam of a channel turn, soak a worm or small piece of cut bait on the bottom in quiet water after sunset for black bullhead.

Along the clean side of a main-lake point, place corn or a dough bait on the bottom along a shallow flat for common carp.

How to Read the Water

Across the lower edge of a creek mouth, do not let the deepest number control the whole day; nearby cover, firm bottom, and food usually matter more than the deepest hole by itself.

Season by Season

Around the first edge of a main-lake point, shallow water is worth a careful look in spring and again during fall; bright summer days favor shade, weeds, or deeper breaks; under ice, a small depth change can be more useful than a long move.

A Simple Tackle Plan

Across the channel lip of an open-water break, a medium spinning rod with 8- to 10-pound line handles most jigs and small casting baits; add a stronger outfit and a proper leader when northern pike are the target.

Across the steep side of a quiet pocket, record the wind, water color, water depth at the strike, and cover after a bite; those four notes are more useful on the next trip than a long list of spots that did not produce.
