Muhammad Abu Farhan, of Barkerend Road in Bradford, got into difficulty at Goit Stock waterfalls on Harden Beck, between Cullingworth and Bingley, on the evening of March 30, at the end of a warm day.
Abu's death was confirmed on the Islamic community page Janaza Announcements on Facebook.
Police said at the time of the incident that there were no suspicious circumstances.
A Gofundme page has also been set up to raise money for orphaned Bangladeshi children in Abu's memory.
Halima Begum, who set up the page, said: "Abu Farhan was a beautiful 14-year-old boy who lost his life tragically battling underwater in Goit Stock waterfalls. He had the most angelic smile and was a well-mannered little boy who was always the first to jump up and help.
"Like any normal teenager, Abu Farhan was enjoying his time with his friends at the waterfall where he found himself in great difficulty when he got into the water and unfortunately was unable to get to safety."
Abu is the second teenager from Bradford to drown while swimming outdoors during a heatwave in the past year. Last July, 18-year-old Mohammed Bilal Zeb, from Chellow Heights, died at Linton Falls in the Yorkshire Dales during a family gathering to celebrate the end of Ramadan. Bilal could not swim but decided to join friends and relatives in jumping off a rock into the extremely cold water. He drowned in less than a minute.
