Looking for an older movie

I’m looking for a movie title about a young kid who is forced to work at a campground for the summer. He finds a new friend, and they go swimming in a river one day and his friend drowns. I have not used this site before, so I’m not sure what is really needed to start a search. Thank you for any kind suggestions.

was it a kids movie? how old is it do you think? was it in english? the kid died?
