Michael Stewart, 6, was found unresponsive when he was pulled from a swimming pool at Liberty Lake Day Camp in Mansfield Township, Burlington County on Monday.
It was the first day of camp for the summer. Camp officials say the boy was in the freshman division, which means he was going into their first or second grade.
Stewart was part of an inclusion program for children with additional or special needs, officials say.
An investigation into his death is now underway.
All of the proceeds from Saturday's lemonade stand are set to go to Stewart's family to help cover the cost of funeral expenses.
