DAYTON, Texas (AP) — Authorities say a 4-year-old boy drowned at Houston-area water park during an outing with his family.

The Liberty County Sheriff's Office says the accident happened late Saturday afternoon at Nine Mile Ranch in Dayton.

The boy's parents were unable to locate the child and began a search using volunteers who walked through the area, then waded into the shallow water. A searcher located the body in the lake. CPR was done but the child could not be saved.

The name of the boy wasn't immediately released.

Dayton is 30 miles northeast of Houston.
