A 20-year-old Georgia woman was killed in a jet ski accident on Lake Lanier — the 12th person to die at the popular reservoir this year, authorities said.

Kaylynn Ticas was riding a watercraft at high speed Saturday around 2:30 p.m. when she crashed into the shoreline, WSB-TV reported.

Bystanders pulled Ticas from the water and she was taken to the Northeast Georgia Medical Center, where she died.

The Georgia Department of Natural Resources said they are conducting an investigation and that the probe could take several weeks.

This year’s death toll at the popular lake has already surpassed the 11 deaths in 2018.

Earlier this month, a 9-year-old boy and his 30-year-old father died after being pulled from the water, according to outlet.

Libao Chen had jumped into the lake to rescue his son Ethan Chen and didn’t immediately resurface. Both were hospitalized in critical condition, and died about a week later.

Lake Lanier, a reservoir in northern Georgia, is “one of America’s favorite lakes,” with 11.8 million annual visitors, according to the US Army Corps of Engineers.
