Post-Plant Behavior & Timing

Since Pablo Reservoir was last stocked June 19, 2008, 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 Pablo Reservoir:
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.
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.
Largemouth Bass Profile Tips
The centerpiece of American bass fishing culture, taken on everything from topwater lures to soft plastics and live bait.
Recommended Tackle for Pablo Reservoir
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.
Gary Yamamoto 5-inch Custom Senko Stickbaits
The heavy salt-impregnated plastic produces a unique horizontal shimmy on the fall around weed beds, docks, and submerged timber.
