At the 2011 Fina USA Diving Grand Prix, the top two divers with the highest cumulative score are selected to represent the United States.

In the men's and women's 25 km race, both held on July 23, USA Swimming recommended its athletes not compete due to "extreme temperature conditions."

USA swimming said the water temperature exceeded its recommended limit and as a result, Alex Meyer and Haley Anderson withdrew from the race.
