Lago Guillelmo

Lago Guillelmo, in Río Negro, Argentina, is the kind of lake where a careful approach pays off. Shore anglers do well casting parallel to the bank along reed lines and overhanging trees, where ambush predators wait. Boat anglers can fan-cast points and submerged humps — anywhere the bottom changes depth quickly. Lure choice at Lago Guillelmo usually mirrors the local forage: small baitfish imitations in spring, larger profiles through summer.

Fishing Techniques

• For Rainbow trout

  Vary your retrieve speed when using spinners to find what triggers a strike; sometimes a slow, steady retrieve works best, while other times a faster, erratic retrieve is more effective.

• For Brown trout

  When fishing streams, focus on seams and current breaks, where trout hold to ambush prey.

• For Common carp

  Pre-bait the area with a similar bait you plan to fish with to attract carp and increase your chances.
