Fishing Tips & Stocking Guide for Colstrip Pond 1
Practical advice on fish behavior, recommended tackle, and state regulations for anglers fishing in Montana.
Post-Plant Behavior & Timing
Hatchery-raised fish are conditioned to pelleted feed and open raceways. Following a release into Colstrip Pond 1, 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 Colstrip Pond 1 was last stocked May 30, 1975, 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 Colstrip Pond 1:
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.
Catfish Rigging
Fish a Carolina slip-sinker bottom rig with a 1/2 to 1 oz egg sinker, swivel, and 1/0–3/0 circle hook. Baits such as chicken liver, cut baitfish (shad), nightcrawlers, and stink baits produce best during early morning, dusk, or night in deeper holes.
Bass & Panfish Approach
Target visible structure such as docks, weed lines, and fallen trees. Small 1/32 to 1/16 oz jig heads with soft plastic grubs or live worms under a float work well for crappie and bluegill; soft plastic worms or spinnerbaits work well for bass.
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.
Northern Pike Profile Tips
Known for aggressive strikes on large spoons, spinnerbaits, and live bait; its sharp teeth call for wire leaders.
Recommended Tackle for Colstrip Pond 1
Field-tested tackle and presentations matched to the species stocked here.
Berkley PowerBait Floating Trout Dough
Hatchery-raised trout are conditioned to pelleted scents; scented dough floated 12–18 inches off bottom consistently triggers strikes.
Panther Martin Classic Teardrop Inline Spinner
The heavy convex blade spins instantly upon retrieval, sending vibration through the water that triggers aggressive reaction bites along drop-offs.
Sliding Sinker & Treble Hook Rigging Kit
Sliding egg sinkers allow cautious trout to run with bait without feeling line drag, while size 14–16 treble hooks keep dough bait securely pinned.
Heavy Duty Offset Circle Hooks (1/0–3/0)
Circle hooks naturally turn into the corner of a catfish's jaw as it turns, preventing gut-hooking and improving hookup rates.
