The Tennessee State Fire Marshal's office issued a report Friday detailing electrical violations at German Creek Marina.
That's where 10-year-old Noah Winstead of Morristown was pronounced dead on July 4th.
His 11-year-old friend Nate Lynam was taken off life support the next day.
Officials say both were electrocuted while swimming near houseboats at the marina.
Several others tried to rescue them and were shocked as well.
Exactly one week ago, TWRA and a marine surveyor visited the marina and determined the cause of the accident, but they have not released the information.
Friday's fire marshal report was in response to the accident, but is separate from the TWRA investigation.

The report does not explain how the children were electrocuted or fault the marina.
10News consulted with former electrician, contractor, and current HEP employee Bill Nichols on the safety inspection report.
HEP is a Knoxville-owned electrical plumping and heating company which sometimes conducts similar safety inspections.
Nichols says the most troubling finding says the marina wasn't properly grounded.
That means electrical feeders supplying the marina and customers didn't have wires connecting them to the ground.
"Grounding" protects people from electrocution by allowing energy to escape to the earth if the feeder accidentally becomes charged and someone touches it.
"I can't say that there are no grounds there at all because I haven't seen the system. But just reading the report, it looks like it wasn't grounded properly originally," said Nichols.
He says the report also states that some of the electrical plugs and wires weren't the kind required for marinas.
Breaker boxes also went unlabelled, according to the document, which Nichols says can make shutting off electricity difficult in an emergency.
He says there was also a note about an exposed wire coming from a light pole and going across a driveway.
There are several more minor violations as well.
"In totality that is a lot of violations that needed to be taken care of," said Nichols.
The state's letter to the marina's owner says they must come up with a plan for fixing the problems or risk having their electricity shut off.
A person who answered the phone at the marina Friday declined to comment on the report.
