The boys were playing with two other youngsters at the Mudong Canal in Vichit, south of Phuket City, when the alarm was raised about 4.30pm.
Pinian ''Gott'' Na Roi-Ead, aged five, was the first to be found. Emergency workers rushed him to Vachira Hospital in Phuket City, but doctors and nurses could not revive him.
The body of his playmate, Wannawoot Tanakan, aged six, was found about 40 minutes later.
Khun Gott was the adopted son of La-Ongsri Deesamer, 46, who said she had cared for him since he was 25 days old.
Khun La-Ongsri's natural son, aged six, was also playing beside the canal this afternoon with his adopted brother.
The parents of both the drowned boys live near the canal. Khun La-Ongsri runs a somtam papaya salad stall near the Rimlay Restaurant.
Emergency workers speculated that one of the boys may have gotten into difficulties and the other boy went to his assistance.
The canal is swollen with heavy rains this month and flowing more rapidly than usual.
A joint Australia-Thai project is underway to establish a lifesaving and learn-to-swim centre on Phuket at Nai harn beach, but the project is in its early stages.
