Recommended Tackle & Presentations
Techniques tailored to the species stocked in Brenneman Slough:
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.
Cutthroat Trout Profile Tips
Known for being relatively easy to catch on dry flies, making it a favorite of western fly anglers; many subspecies are managed under catch-and-release rules to protect native populations.
