The bulk of the collection is documentation for engineering projects where Dr. Sagar either designed, advised on, or reviewed the gates and/or valves involved. Projects involve countries on four continents and at very wide ranging scales. The collection also contains papers, publications, and presentations by Dr. Sagar along with some general documentation of his career. The majority of the collection is in English, but several other languages are also present.

As a hydro-mechanical engineer, B. T. A. Sagar specialized in gates and valves for irrigation and hydropower projects around the world. He designed or reviewed gates and valves for some of the largest such projects.
Bokkapatnam Tirumala Ananda Sagar was born in Guntur, India, in 1929. He earned an undergraduate degree in civil engineering from Andhra University (1950) and an M.S. from the University of Colorado (1959). A decade later he enrolled in Colorado State University and completed his Ph.D. in hydraulics and hydromechanics in 1973.
Over nearly two decades (1950-1969), Sagar worked his way up as assistant director, deputy director, and then director of the Central Water and Power Commission for the government of India in New Delhi. He was responsibile for the gates and hoists at most of the major dams and hydropower projects in the country.
In the United States, Sagar worked for Engineering Consultants International (ECI) (earlier called PRC Engineering Consultants) in Englewood, Colorado, starting in 1969. There he was responsible for hydro-mechanical equipment used at many hydropower and irrigation projects around the world. He was vice president of ECI from 1999 to 2001 and became an independent consultant after retirement. Beyond India, his work involved facilities in Indonesia, Thailand, the Philippines, Peru, and other locations. U.S. locations included Puerto Rico and several western states.
Sagar's professional activities included service as a consultant to both the United Nations and the World Bank. He held professional memberships in the American Society of Civil Engineers, U.S. Committee on Large Dams (USCOLD), International Water Resources Assocation, and Sigma Xi. He was the founding chair of the USCOLD Subcommittee on Gates and Valves. He also published a number of articles and gave several conference presentations on subjects relating to various types of gates.
B. T. A. Sagar and his wife B. T. Yashoda married in 1962 and had two children, son Mohan and daughter Sangeetha. They lived in the Denver metro area and in Colorado Springs. Sagar was proficient in six languages and was a devout Hindu. Sagar passed away in 2017.

Language of Materials
As a hydro-mechanical engineer, B. T. A. Sagar (1929-2017) specialized in gates and valves for irrigation and hydropower projects around the world. The collection includes representative projects from across Dr. Sagar's career and a variety of countries in which he worked. The bulk of the collection is documentation for engineering projects where Dr. Sagar either designed, advised, or reviewed the gates and/or valves involved, along with his papers, publications, and presentations.
The collection consists of 2 series in 6 boxes:
Series 1: Professional activities, 1963-2016 and undated
Series 2: Projects, 1965-2015 and undated
The Papers of B. T. A. Sagar was donated by his daughter Sangeetha Sagar in March and June 2018.
The collection was sent to the Archives by Dr. Sagar's family. Materials had little to no organization and were not in the cleanest condition. In sorting through the materials, it became apparent that many documents that could be identified as part of specific projects contained proprietary information. Ultimately, what was retained are materials by Dr. Sagar that were clearly, or highly likely, not contractually restricted and that were representative of his work. Some large sets of materials related to projects he worked on, even if his contributions were not specifically indentified, were retained as examples. Drafts, duplicates, reference materials, government documents, vendor literature, personal mail, religious flyers, unidentified materials, and moldy items were generally not retained.
Processing was completed in July 2018. Materials were rehoused in acid-free boxes and folders as needed. One item was cleaned of mold. The floppy disk and CDs were backed up on the library's digital server.
