Divers performing routine maintenance at the Converse Reservoir dam on Big Creek Lake on Wednesday found a grenade-type improvised explosive device (IED) submerged underwater, directly threatening the primary drinking water supply for the entire city of Mobile and surrounding areas.
The device was located during a scheduled underwater inspection of the dam.
The Mobile Area Water and Sewer System (MAWSS) immediately alerted the Mobile County Sheriff’s Office, which coordinated a multi-agency response involving the Gulf Coast Regional Maritime Response and Render-Safe Team, the FBI Bomb Squad, Mobile Police Department Explosive Ordinance Detail, ALEA Bomb Squad, and Daphne Search and Rescue.

The team safely retrieved the IED and detonated it off-site with no injuries or damage to the dam or water supply.
MAWSS Director Bud McCrory issued a statement emphasizing the seriousness of the incident to local station Fox 10.
“Our top priority is keeping your drinking water safe,” McCrory said. “This is an unprecedented threat, and we are fortunate that this device was discovered before it could cause serious damage to our water supply or harm to individuals. We are grateful for the professionalism and competency of our law enforcement partners – as well as the quick thinking of our contractors and divers – in identifying this device and safely destroying it.”

Built in the early 1950s, the lake supplies roughly 60 million gallons of drinking water per day to hundreds of thousands of residents in Mobile and surrounding communities.
Officials have confirmed the water supply was never compromised and remains safe.
As of Thursday afternoon, no suspects have been named, and no motive has been publicly disclosed.
The FBI and local law enforcement are actively investigating how the device ended up at the dam.
The Department of Homeland Security has also been notified.
Authorities have not released details on the exact construction of the IED beyond describing it as a grenade-type improvised explosive.
The Gateway Pundit will continue monitoring the investigation for any updates from the FBI, Mobile County Sheriff’s Office, or MAWSS.
