Largemouth bass fishing at El Salto and Mateos reservoirs is a secret treasure. This is where the pros you see on Saturday morning TV go to get game. Top water action can be breath-taking with double-digit fish not uncommon. Excellent all-around service with two wonderful lodges, incredible meals, terrific staff and a serious American-trained commitment to bucketmouths on the fly. 8- to 10-wt rods, floating and sink tip lines, easy casting from well maintained boats.
