In 1930, he was scouted by Athletic Director Darwin Meisnest, to serve as swimming coach and program manager of the Washington Athletic Club on Sixth and Union Streets in downtown Seattle. Athletic Director Meisnest was a former Manager at Washington University who had helped procure funds for the University of Washington's
Husky Stadium in 1920. The 101 Club, which was also part of the Washington Athletic Club organization, included many of Seattle's wealthiest citizens, who occasionally acted as athletic sponsors for WAC's more gifted athletes. After over 20 years as a swim Coach and program manager, Daughters was appointed WAC Director of Athletics in 1946. At the Silver City Water Pageant at Liberty Lake on June 16–17, 1934, Daughters featured several of his best-known Washington Athletic Club swimming proteges including Jack Medica, Olive McKean, Doris Buckley, and Mary Lou Petty. McKean broke Helene Madison's world record with her own record of 3:54.4 in the 300-yard swim. Medica swam 500-yards in a new American Record time of 5:46, and swam 500 meters in a record time of 6:24.6. The Washington Athletic Club women's relay team swam a 2:15.5 for the 220-yard freestyle relay. During his accomplished tenure as swim coach, Washington Athletic Swimming Club captured 30 world records, 301 American records and placed first in 64 National Championships. In 1935, his women's 4x100 freestyle women's relay team composed WAC swimmers Mary Lou Petty, Betty Lea, Doris Buckley and Olive McKean won the U.S. National Champion in Chicago in world record time, and again won the championship in the same event in 1936. Daughters also coached Bob Miller, an ASCAA Hall of Fame swimmer and Coach who worked as Washington Athletic Club's Assistant Coach from 1951-1955 and later coached the Olympic Swim Club.
