With the controversy over the planned Echo Park Dam in Dinosaur National Monument in the late 1940s and early 1950s, many people like Andrew Pfeiffenberger turned to Bus Hatch and his sons, Don, Ted, and Frank, to take them down the Green and Yampa Rivers. During the controversy, Hatch River Expeditions outfitted river trips for both pro-dam and anti-dam groups, trips that often included over 100 people. This was the true genesis of Hatch River Expedtions. After the controversy, and through the 1960s, the name Hatch became synonymous with river running, especially in the western United States. By the end of the 20th century, Hatch had become one of the best-known river outfitters in existence, and there are now 3rd generation members of the Hatch family who are still in the river running business.
