Staff ReportsDivers doing routine work at the Converse Reservoir dam in Mobile, Alabama found something no one wants to find in their drinking water supply: a grenade‑type improvised explosive device. MAWSS called it “an unprecedented threat,” and federal and local bomb squads stepped in to retrieve and safely detonate the device. The discovery should wake up every elected official who treats water security like a second thought.
What happened at the Mobile dam
Workers from the Mobile Area Water and Sewer System (MAWSS) were on a routine dam inspection at Big Creek Lake, also known as the J.B. Converse Reservoir, when divers spotted the device. The Gulf Coast Regional Maritime Response and Render‑Safe Team, the Mobile County Sheriff’s Office, FBI bomb technicians, the Alabama Law Enforcement Agency bomb squad and other specialists all joined the multi‑agency response. The device was safely detonated and there were no injuries. MAWSS notified the Department of Homeland Security and rightly called the find “an unprecedented threat,” a striking phrase for a routine maintenance dive.
Why finding an IED in a reservoir matters
This reservoir is not a pond behind a grocery store. The Converse Reservoir is the primary drinking water source for Mobile and nearby communities, holding roughly billions of gallons and serving tens of thousands of people. A grenade‑type IED stuck under a dam could have meant catastrophic damage, contamination, or a shutdown of water service. That’s why critical infrastructure must be treated as critical — not as something to be fixed after an incident makes headlines.
Accountability: who should answer for this?
We don’t yet know who put the device there or why. That gap is not an excuse for complacency. Local officials did the right thing by calling in state and federal teams, but we need answers and faster action from the Department of Homeland Security, the FBI and political leaders who control budgets and priorities. If someone can place a bomb near a reservoir, questions about security plans, perimeter patrols, fencing, cameras and prosecution must follow. We should not rely on luck or the keen eye of contractors to keep our taps safe.
What must happen next
MAWSS says it will “enhance security” at the reservoir — good. But words must turn into clear steps: immediate water‑quality testing, visible security upgrades, criminal and counterterrorism investigations with public updates, and funding for long‑term protections of critical infrastructure. Elected officials in Mobile and in Washington should stop with the press releases and start with real fixes. Our water is not a political talking point; it is a public good that deserves action before the next headline.
