The incident happened around 5 p.m. in the 15000 block of West Airport, according to a tweet from Fort Bend County Sheriff's Office.
Authorities say the 3-year-old was at an apartment complex pool with his family.
The toddler, who did not know how to swim, was wearing flotation devices on his arms and waist when a family took them off when it was time to eat.
According to authorities, the child slipped away to try and sit by the pool but fell in.
The child's father noticed he was missing and jumped in the water to try to save him, but it was too late.
