The Navy report is silent on the emotion of the moment, which must have been extreme among the tight-knit group of divers.

Almazan was in contact with Senior Chief Diver Burger, who was Reyher’s and Harris’s supervisor and was observing with alarm from shore. Burger, too, was being evaluated, according to someone with knowledge of the case.

Almazan said that there had been “an incident” and that he needed more rescue divers.

He told Burger to call 911. Burger rushed to the scene in a second boat, according to the person with knowledge of the case.

As the anguished seconds ticked by, two more divers were sent down. But they reached only 120 feet before they had breathing problems and ran out of allotted time.

Finally, by pulling the tending line in a different direction, Reyher and Harris were brought to the surface. Harris came up first. He had the tending line wrapped around one arm.

Fellow sailors got them out of their gear — Reyher’s was covered in mud — and started CPR. Both men were rushed to the recompression chamber. Harris was later taken by helicopter to a local hospital where he was pronounced dead.

Reyher was already deceased.

The super pond today

Last week, an Army spokeswoman said the super pond is still closed and may remain so until spring.

But early last month, four unarmed ordnance items were removed from the bottom as part of a cleanup. The Army did much of the work but needed the Navy’s help.

A diver was required to go down and see that some connections were sound, a Navy spokesman said.

The job fell to MDSU2.
