Techniques tailored to the species stocked in Grass Lake Tlm:

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.

Brook Trout Profile Tips

Arctic Grayling Profile Tips

A popular dry-fly target in Montana and Utah's high-country waters, prized for its willingness to rise.
