Staff Reports
Divers doing routine maintenance at the J.B. Converse Reservoir dam in Mobile, Alabama found something that should make every local and federal official hit the panic button: a grenade‑style improvised explosive device (IED) planted underwater near the dam. The device was pulled out and safely detonated by a multi‑agency bomb team, and authorities are calling the incident “an unprecedented threat.” That description is not hyperbole — it’s a wake‑up call.
What happened at the Converse Reservoir
MAWSS crews discovered the grenade‑type IED while inspecting the Big Creek Lake dam. The Gulf Coast Regional Maritime Response and Render‑Safe Team, along with the Mobile County Sheriff’s Office, the FBI bomb squad, Mobile Police Department EOD, the Alabama Law Enforcement Agency bomb squad, and Daphne Search and Rescue, handled the recovery and a controlled detonation. There were no injuries and no catastrophic damage — thank goodness — but that’s a miracle, not a policy.
The J.B. Converse Reservoir supplies tens of millions of gallons of drinking water per day to the Mobile area. MAWSS Director Bud McCrory called the find “an unprecedented threat” and said the utility notified the Department of Homeland Security. That is exactly what should happen. A device placed at or under a dam is not a prank; it’s an attack on critical infrastructure and on public health.
Why this matters — and why answers are needed
Imagine if that grenade‑style device had worked as planned. A detonation near intake structures or treatment facilities could disrupt water treatment, damage infrastructure, and, in a worst‑case scenario, cut off drinking water to hundreds of thousands of people. The technical details of the device, who placed it, and why are still being investigated. For now, there are more questions than answers — and rightfully so. The public deserves straight talk about motive, suspects, and forensic findings.
It’s also worth noting that MAWSS has been tightening access to Big Creek Lake in recent months. Security measures that limit casual public access make sense when infrastructure is threatened. But security needs to be real and consistent, not a slogan. If we are going to treat our water system like critical infrastructure, then we need critical infrastructure security — not a patchwork of lawsuits and press releases.
Practical steps we should demand
Federal, state, and local officials must move beyond statements and do three things right away: harden the site, hunt down the perpetrators, and publicly explain the findings. Hardening means better perimeter control, increased surveillance (including drones where appropriate), regular EOD sweeps, and redundant monitoring at intake and treatment points. Hunting down perpetrators means the FBI and U.S. Attorney’s Office treating this like the serious federal crime it is. And the public deserves transparency on what was found and how future attacks will be prevented.
Let’s give credit where it’s due: the bomb crews and divers did their jobs and likely averted disaster. Now the rest of the machinery — law enforcement, Homeland Security, and local leaders — must do theirs. If an IED at a municipal dam doesn’t spur urgent, sustained action, then we’re fooling ourselves about how much we value the most basic public service: safe drinking water.
