An 11-year-old boy who died after he fell in a canal in Burnley "always had a smile on his face", his headteacher said.
Robbie Williamson walked across a pipe on a canal bridge before he lost his balance and plunged into the water.
A passer-by jumped into the Leeds and Liverpool Canal at Lowerhouse Lane and pulled the youngster out and he was given CPR before emergency services arrived.
The Year 7 pupil at Shuttleworth College in Padiham was then taken to Royal Blackburn Hospital but later died.
Bob Wakefield, headteacher at Shuttleworth College, said: "Robbie was such a good lad who worked hard and always had a smile on his face. He was very popular with his classmates and was bursting with energy.
"He was very friendly and well-behaved, and when he came in to school he got on with things straightaway without any fuss.
"This is a terribly sad day for everyone in the school, and our thoughts are with Robbie's family at this very difficult time."
