What few knew was that another nearby lake (Lago Quiroga) was also initially stocked years ago, and that lake (as well as a series of lagunas, the inlet and outlet to that lake on Rio Capitan, the river itself, and a nearby spring creek) also burgeoned with populations of rainbows eating aquatic-insect steroids and exploding in size as a result. That fishery has been under wraps. I first got wind of what was happening here in 2008, when I fished with brothers Alex and Nico Trochine on the Rio Irigoyen. It's been in development since then, but now, the brothers Trochine and their company, Faraway Flyfishing, have teamed with Untamed Angling (which runs the fabled Tsimane Lodge for dorado in Bolivia) to open Kooi Noom. And I'm here now.
