Emergency crews were called to Roe Valley Park in Limavady, Co Londonderry, at around 4.30pm on Thursday.
It is understood the boy may have gone into the water to retrieve a football but got into trouble.
He was airlifted by police helicopter to Altnagelvin hospital where he later died.
The PSNI said: "The teenager is believed to have drowned after falling into the River Roe."
Roe Valley Park is managed by the Northern Ireland Environment Agency.
I cannot advise people strongly enough of how dangerous rivers, reservoirs and quarries are and my clear message is 'stay out of the water and stay safe'.
Mark H Durkan
Mr Durkan has expressed his sympathies to the boy's family following the "terrible tragedy" and has asked for an "urgent" report from officials.
"Given that DOE manages Roe Valley Country Park I have asked my officials for an urgent report on this tragic incident," the SDLP minister said.
"This is a terrible tragedy. My heart goes out to the family of the teenager and I offer them and his friends my deepest sympathy."
Local councillor Alan Robinson, of the DUP, said the borough was shocked by this "desperately sad news".
He continued: "To know that one of our young people lost their life yesterday in this borough places a very heavy heart on us all.
"Any young children in and around water should be very careful and look out for the dangers."
Last month 39-year-old Collin Pollard died trying to save a teenager who got into difficulty while swimming in a quarry close to Annalong, Co Down.
Kevin O'Hare, who was 15, also lost his life in the incident.
We would appeal to parents to explain to their children the dangers of playing in or around these areas.
The DOE has since launched a campaign to highlight how dangerous Northern Ireland's 3,000 disused quarries can be.
NI Water also put out a message for children and young people to stay away from reservoirs.
A statement from the company explained: "Water may look safe, but it can be dangerous, which is why people need to learn to spot and keep away from dangers. You may swim well in a warm indoor pool, but that does not mean that you will be able to swim in cold water."
There has also been a call from the Royal National Lifeboat Institution for people to be careful at the beach.
They said: "The RNLI's advice is to choose a lifeguarded beach and swim between the red and yellow flags, which is the area most closely monitored by the lifeguards."
