Agua Negra
Four Species, One Grand Slam
Week 16 brought five anglers from Switzerland to Agua Negra for a week of excellent weather, low clear water and highly productive fishing.
The group found strong opportunities for both dorado and pacú throughout the system, including a 20-pound dorado for Heinz on the Sécure and a particularly visual encounter for Claude in the Upper Agua Negra.
But the defining achievement came on the final day.
Stefan completed an extraordinary four-species Grand Slam, landing pacú, dorado, surubí and yatorana in a single day.
The Chimoro added another highlight, with Claude, Grégoire and Stefan making a long walk into a remote section of the river and finding excellent fishing waiting at the end.
5 Stefan, Konrad, Heinz, Grégoire & Claude (Switzerland). Stefan and Konrad stayed with us for two weeks.
Weather remained excellent throughout the week. Sun and warm temperatures dominated, with only one particularly windy day breaking the pattern.
The rivers remained low and clear throughout the week. Those conditions provided excellent fishing opportunities across the system, with active dorado and pacú appearing in a variety of environments.
Catch of the Week
Twenty Pounds from the Wood
Heinz landed the largest dorado of the week on the Sécure.
The fish appeared in an area of submerged wood known for producing opportunities and weighed approximately 20 pounds.
It became one of the week’s strongest individual catches and another reminder of how productive these structured sections can be when the river is low and clear.
Memorable Moments
Four Species in One Day
On the last day, Stefan pulled off a spectacular Grand Slam.
Not three species.
Four.
Pacú, dorado, surubí and yatorana, all in a single day.
Claude’s Perfect Shot
Claude’s dorado in the Upper Agua Negra was straight out of a movie.
We saw the fish perfectly, he made the perfect cast, and the dorado responded: it gave us an incredible fight.
What followed was an explosive take and a powerful fight, turning a textbook sight-fishing opportunity into one of the most cinematic moments of the week.
Deep into Chimoro
Claude, Grégoire and Stefan made a long walk to a very remote stretch of the Chimoro.
The effort paid off.
They found excellent fishing and several quality dorado, turning a demanding approach into one of the week’s most productive days.
The Week at Agua Negra
Low, clear rivers and stable weather allowed the group to explore very different parts of the system.
A 20-pound dorado from the wood, a four-species Grand Slam, a perfect shot in the Upper Agua Negra and a long walk into Chimoro gave Week 16 a remarkable range of fishing.
For next week, there is some rain in the forecast, but for now nothing suggests it will significantly affect fishing conditions.
See you next week.
