When the Rio is "on" it is fantastic!! At other times it is known locally as a "stingy river." Thunderstorm activity and irrigation upstream make summer on the Rio unpredictable. From mid September through October flows reach their natural level and water clarity improves. Fish are very active and accessible during this period. Fish dry flies in pocket water and nymphs in deeper runs. Best fishing here is in the upper gorge, above the confluence with the Red River, a one mile hike into the 800 vertical foot gorge. Fish here are mostly Browns with some good size Cuttbows in the deeper runs.

The Lobato (Costilla Crossing) Bridge is the southernmost bridge over the Rio Grande River in Colorado. It sits on County Road G between Antonito and Jaroso, Colorado and was originally constructed in 1892 by Joseph F. Thomas. He was a civil engineer and the Conejos County Surveyor and lived in Manassa, Co.. The bridge was purchased from the Wrought Iron Bridge Company of Canton, Ohio for the sum of $8,400. The bridge parts were shipped to Colorado by train and assembled on location.

Also known as the Old State Bridge, it has been listed on the National Registry of Historic Structures since 1985. The bridge stretches 313.9 feet long with a deck width of 15.7 feet.
