Multiple Grand Lake incidents have seen the deaths of two people and the injury of a five-year-old.

 Grand River Dam Authority spokesman Justin Alberty says the first incident claimed the life of 54-year-old Eric Peterson, of Belton, Missouri. Peterson died Friday in an ATV crash in the off-road area below Pensacola Dam. Peterson, who was not wearing a helmet, was riding the ATV up a hill when it overturned.

 A second incident claimed the life of an 87-year-old Kansas man, who died in the Honey Creek arm of Grand Lake. The man, whose name hasn't been released, fell into the water while trying to step from a boat onto the dock. Alberty says GRDA officers responded to the scene shortly before 2:00 p.m. and recovered the man’s body.

 The third incident happened Saturday evening, as a boat exploded near the Check-in Bay area of Grand Lake. A 5-year-old child was taken to Hillcrest Hospital in Tulsa with unknown injuries.

 Alberty says that incident is still under investigation.
