The Aquatic Club Records collection contains brochures, newspaper articles, photographs, correspondence and hand-written notes. The bulk of the materials are from the Water Carnivals put on by the club from 1954 to 1958. These materials were donated by Dr. William A. Yorzyk and include notes and statistics on the carnivals (including the results of the races held), newspaper articles published before and after the carnivals, and brochures that are often marked with results of the races. There are also a few photographs of club members and a scene from one of the carnivals (ca. 1938-1960).
