This Lagoon is approximately eight kilometers long and nearly five kilometers wide and offers an excellent habitat for waterfowl populations wintering in Mexico. Recent estimates have indicated that the area is home to some 800,000 birds during the North American winter. Among the species found in the Lagoon are the Pintail, American Widgeon, Redhead, Canvasback, Lesser Scaup, Northern Shoveler, Gadwall, Mexican Duck (which is endemic), Greater Scaup, Ruddy Duck, Blue Winged Teal, Green Winged Teal and Cinnamon Teal.

Hunting this Lagoon offers an experience unique to the highlands of central Mexico. Two thirds of the lagoon, situated at 8300 ft. above sea level, is covered with thick, tall bullrushes, interspersed with boat trails and small natural openings. Since the water is uniformly 2-3 feet deep throughout, travel is accomplished by long, narrow, bipointed skiffs poled by hand. Hunters are lined up about 40-50 meters apart along the trails all facing in the same direction. "Beaters" sent out in separate boats, one for each hunter, begin a noisy "drive" about 5-600 meters in front of the hunters and advance thru the reeds towards the hunters.

The flushed birds fly out over the hunters, providing exciting and varied shooting. When the beaters arrive at the line of hunters, your guide will borrow the narrow, beaters boat and pole thru the reeds to retreive your downed birds which he has carefully memorized the location of by a system of bent reeds pointed toward them. As noted Florida bird taxidermist and waterfowl hunter Tony Gilyard stated "This was the most interesting and unique duck hunt I have experienced. The ability of the guides to mark and retreive birds under these conditions defies belief. Truly a wonderful experience."
