A recent article in The Blaze caught my eye — the kind of headline that makes you sit up and take notice: a bomb had been discovered underwater at the base of an Alabama dam. As it turns out, the story is more interesting for what it reveals about bureaucratic incentives than for any genuine threat to national security.

On May 12, 2026, divers conducting routine maintenance and repair inspections at the J.B. Converse Reservoir dam — also known as Big Creek Lake — near Mobile, Alabama, discovered an underwater “grenade-type improvised explosive device” (IED) near the dam’s base. Authorities described the device as such. The device was retrieved and safely detonated by a multi-agency bomb disposal team.

The Mobile County Sheriff’s Office coordinated with the Gulf Coast Regional Maritime Response and Render-Safe Team, the FBI Bomb Squad, the Mobile Police Department Explosive Ordnance Detail, the ALEA Bomb Squad, and the Daphne Search and Rescue Team. Homeland Security was notified because the reservoir is designated as federally protected critical infrastructure.

The Mobile Area Water and Sewer System (MAWSS) Director Bud McCrory wasted no time characterizing the discovery as an “unprecedented threat.” He stated that the device “could have caused serious damage to our water supply or harm to individuals.”

Officials also raised the specter of contamination of the freshwater supply, in addition to structural damage.

The numbers cited were indeed dramatic. The J.B. Converse Reservoir is a 3,600-acre man-made lake holding approximately 17 billion gallons of water — the sole drinking water source for an estimated 350,000 residents of the Mobile area, producing roughly 60 million gallons of drinking water daily. A failure of that supply would be genuinely catastrophic for the region.

Here is why the story deserves a second look. The question is not whether the device was dangerous. It obviously was. The question is whether it posed a serious threat to the dam or the regional water supply.

The device was described as “grenade-type” — a relatively small, low-yield improvised explosive. It was not a shaped charge. It was not a large quantity of military-grade high explosive placed at a structurally critical point. It was a grenade-like object found at the bottom of a reservoir.

Anyone with knowledge of structural engineering or military demolitions will tell you that concrete gravity and earthen dams are extraordinarily robust. Breaching one requires tons of precisely placed explosives delivered to exact structural weak points. During World War II, the famous “Dambusters” raid (Operation Chastise) required custom-engineered 9,250-pound bouncing bombs carrying roughly 6,600 pounds of Torpex, which were dropped at precise angles and depths after months of testing — and even then, the results were mixed. A single grenade-type device on the floor of a reservoir would, in all likelihood, produce a loud bang and some dead fish.

This raises an obvious question: was someone fishing?

Blast fishing — the practice of using explosive devices to stun or kill fish, which then float to the surface for easy collection — is illegal in most of the world but remains widespread, particularly in rural and semi-rural areas near large bodies of fresh water. The reason is simple physics: an underwater explosion generates a concussive shockwave that radiates outward, rupturing the swim bladders of fish within range. Most sink; a few float to the surface. It is crude, destructive, and surprisingly common among people who want fish and have little patience for a rod and reel.

This fishing method was common during the Vietnam War. Both American soldiers and their South Vietnamese allies routinely used hand grenades for fishing, and veterans have written and spoken openly about it for decades.

The practice made practical sense in that context:

• Grenades were abundant and readily available — soldiers carried them as standard issue
• Conventional fishing was time-consuming; a grenade produced immediate, large results
• South Vietnamese soldiers and civilians taught American troops the technique, so it had deep local roots long before U.S. involvement
• U.S. Navy Brown Water sailors on river patrol boats specifically used concussion grenades for fishing — the lead boat would drop one, and the crew would collect the stunned fish floating to the surface
• One veteran recalled using even a blasting cap from a disassembled grenade to stun fish for local children, who were amazed by the haul

The legacy literally outlasted the war — as late as 1996, a Vietnamese man was killed while attempting to fish with an American Vietnam War-era hand grenade that had been stored since the conflict ended.

A large reservoir full of largemouth bass, catfish, and crappies, accessible to anyone driving through the area, is precisely the kind of target a rogue fisherman might choose.

As of this writing, there have been few follow-up news accounts or official statements beyond the initial alarm. As of May 14, 2026, the FBI and the Department of Homeland Security had not issued public statements. No suspect has been identified. No motive has been established. No additional devices have been reported.

What has been reported is that MAWSS plans to “beef up security” at the dam in the wake of the incident.

That costs money — and money requires a compelling justification for elected officials. The phrase, “We found what appears to be improvised fishing gear” does not move the needle. “Unprecedented threat to critical infrastructure serving 350,000 people” absolutely does.

No doubt the funding request will be approved.

None of this is to suggest the MAWSS director is cynically dishonest. He may genuinely believe the threat framing or be very cautious. But institutional self-interest and honest threat assessment often yield identical outcomes in these situations — making them nearly impossible to distinguish from the outside.

This pattern plays out across government and quasi-governmental agencies at every level, hundreds of thousands of times a year. Every incident becomes a justification for expanded resources. Every expanded budget becomes next year’s baseline, virtually impossible to cut. Every director whose job security depends on organizational growth rather than efficiency has every incentive to see threats as larger than they are and no incentive for restraint.

The national debt does not accumulate only from dramatic policy failures and trillion-dollar programs. It accumulates incrementally, one security upgrade at a time, one “unprecedented threat” press release at a time, multiplied across every water authority, transit board, school district, health department, and municipal agency in the country.

A grenade-type device found at the base of a dam in rural Alabama might have been part of an actual terrorist plot, though an apparently incompetent one. My bet is on some local redneck who decided to go fishing.

Nevertheless, whoever was responsible will most likely produce a very real and lasting consequence — a budget line item that will outlast us all.
