Post-Plant Behavior & Timing

Since Grayling Lake Number One was last stocked April 21, 1966, anglers visiting within 1 to 2 weeks of a reported event generally experience the highest activity before fish disperse into deeper cover.

Recommended Tackle & Presentations

Techniques tailored to the species stocked in Grayling Lake Number One:

Stocked Trout Tactics

Use light 4–6 lb monofilament or fluorocarbon line. Float scented dough bait (PowerBait) 12–18" off bottom using a sliding slip-sinker rig with a size 14–16 treble hook. For active casting, throw 1/16 to 1/8 oz inline spinners (Panther Martin, Rooster Tail) or small spoons (Kastmaster) along drop-offs.

Rainbow Trout Profile Tips

The most commonly targeted stocked trout in the country, taken on bait, spinners, and flies alike; a common first fish for new anglers.

Brook Trout Profile Tips

A favorite of high-country and small-stream anglers; often more willing to strike than brown or rainbow trout in the same water.
