JURASSIC LAKE LODGE, ARGENTINA PATAGONIA

 Had the opportunity to fish for monster rainbow trout at Jurassic Lake Lodge during September 20 to 27, 2025.  Jurassic Lake, a.k.a. Lago Strobel is without a doubt the greatest rainbow trout fishery on earth.  Here, 20 lbs rainbows are caught on a weekly basis.  Lago Strobel is about a 5 hour drive from the town of El Calafate.  Jurassic Lake Lodge sits next to the Rio Barrancoso which is the only inlet in Lago Strobel.  Here, tens of thousands of rainbows make the push for spawning in September. 

September is the beginning of season while May is the end of the season.  Strobel is known for strong winds which can make fly casting a challenge.  Spinning and or casting gear is allowed in the lake.  The best places are on either side of the river mouth. 

The fishing during the week was good but the numbers are not what I have experienced in the past.  This was in my opinion due to the weather being too nice, no winds and high sun.  The best fishing was very early in the morning before the sun came up.  I would skip breakfast and head to the mouth wearing a headlamp.  The best fly was a white mop using an 8 wt, while casting a 5/8oz moonshine casting spoon in red bloody glow is without a doubt the best lure one can use on Strobel.  I probably have fished here over 20 times and have had numerous days exceeding 100 rainbows.  My best session on this trip was 42 rainbows during the morning with the majority landed before 8am.  The largest weighed rainbow was caught by friend, Jim, which pushed the Boga to a tad over 20 lbs.  My largest pushed the measuring tape to 36 inches.  

The water levels were low but came up the last day of the trip.  There were thousands of rainbows in the Barrancoso, but we did not fish in the river.  As you might know, last January the river got blown out with massive amounts of water rushing through.  The famous "aquarium" hole is now a pile of rocks and dirt.  The river flow changed thus pushing it's mouth down to the right about 50 yards.  

In all, the trip was fantastic.  The average rainbow in my opinion was 11 to 12 lbs.  There is no place on earth where one can constantly caught this size of rainbow trout wading with a fly rod in an isolated, pristine setting.  I will again return in May to catch the giant chrome rainbows which is the favorite time at Jurassic Lake Lodge.
