Post-Plant Behavior & Timing
Hatchery-raised fish are conditioned to pelleted feed and open raceways. Following a release into Lost Lake, they typically congregate in schools near public access points, boat ramps, or inlets for the first 24 to 48 hours while adjusting to natural water conditions.
Since Lost Lake was last stocked May 13, 2026, 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 Lost Lake:
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.
Kokanee & Salmon Tactics
Troll small dodgers followed by micro-hoochies or wedding ring spinners tipped with shoepeg corn. Use downriggers or lead-core line to reach cooler thermocline depths (typically 20–50 ft in summer).
Kokanee Profile Tips
Usually caught by trolling small lures or bait behind flashers at depth; a major fall spectacle when spawning runs turn red in tributary streams.
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.
