Abstract In 1911, the Irrigation Investigations Unit of the U.S. Department of Agriculture was established in Fort Collins in conjunction with Colorado Agricultural College (now Colorado State University). Scientists within the unit, including Ralph Parshall, Carl Rohwer, Victor M. Cone, and William E. Code, conducted irrigation-related research. They studied and designed apparatuses to measure water flow through canals and diversion structures, investigated various irrigation projects, and conducted...

Abstract Louis G. Carpenter (1861-1935), irrigation engineer, was appointed professor and head of engineering and physics at the Colorado Agricultural College in 1888. He became director of the Colorado Experiment Station at that institution in 1899 and remained at the college until 1911. Carpenter initiated the first systematic instruction in irrigation engineering, consulted widely on irrigation and hydraulic construction projects, and was also consulted for his expertise in water law. The...

Abstract Ralph Parshall contributed significantly to the field of irrigation engineering with the development of a flow-measuring device that became commonly known as the Parshall flume and continues to be widely used. Materials in the collection include Parshall's patent on his "Venturi flume water stage recording instruments," awards that Parshall received, publications, copies of talks he presented on KOA radio in Denver, and a number of lantern slides depicting flumes, weirs, plans, and...
