The calva (common fat snook) run is still on in the Rio Colorado (usually mid-November through December). Many anglers inquire about this species - but even when we're fishing for them, the mighty Silver King is liable to show up! Here, our guide Guinder was out in the arly mrning catching calva when a big 120 lb tarpon showed up! Guinder landed him on his calva rig (calva top out at 5 kilos!). Guinder had a great day - 20 snook and 3 tarpon - all in the river just up river from the Lodge. If you want to catch snook, now is the time!
