Albert Yin from Maryland drowned in late June while swimming in the lake which is popular bathing spot in summer.
The boy was rescued by a police diver and resuscitated at the scene. He was then airlifted to hospital. But he later died at the facility.
Albert was a great ice hockey player and pianist, according to comments made by his family to US broadcaster CBS.
"Over the summer, we go to perform in prestigious venues overseas. So this year, we had gone to Italy and we had gone to Switzerland and after our concerts, we would go to do vacation and touristy things," his sister Margaret told CBS.
The day before Albert died, the 13-year-old had performed the Hungarian Rhapsody by Liszt at the Culture and Convention Centre (KKL) in Lucerne.
