Lago Lolog

Lago Lolog venue image

Lolog lies close enough to San Martín de los Andes to draw a mixed crowd of anglers and holidaymakers, but the fishing holds up: glacial-volcanic water full of brown and rainbow trout that respond well to streamers worked along the drop-offs and rocky points away from the main beaches.

How to fish it · for Trout
When
No strong hatch signals at the moment — general searching tactics should work best. Calm conditions may limit drift fishing — consider buzzers or dry fly if fish are rising.
Where
With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the calm, a single dry fly or a slowly-fished nymph tends to out-fish an active retrieve. When no hatch is visible, a buzzer team — black stripped quill on the point, attractor or pearl-rib on the top dropper — is the default starting point on any UK stillwater.
The plan
Plan A

With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the calm, a single dry fly or a slowly-fished nymph tends to out-fish an active retrieve. When no hatch is visible, a buzzer team — black stripped quill on the point, attractor or pearl-rib on the top dropper — is the default starting point on any UK stillwater.

Plan B

If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Bank

Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.

About this water

Lolog lies close enough to San Martín de los Andes to draw a mixed crowd of anglers and holidaymakers, but the fishing holds up: glacial-volcanic water full of brown and rainbow trout that respond well to streamers worked along the drop-offs and rocky points away from the main beaches. A Woolly Bugger or Zonker stripped past structure in the early morning, before boat traffic picks up, is the reliable approach, and shoreline access is good enough to fish effectively without a boat. The season here runs long by regional standards, extending toward the end of October with catch-and-release expected once the standard window closes, and trolling rules have shifted in recent regulation cycles — worth confirming before heading out. It's an easy lake to fish for an afternoon and a good option when wind has closed down the bigger water nearby.
