Treasure hunting on the American River is a tradition passed on from generation to generation for one Carmichael family.

Karl Bly, a Carmichael resident, lives along the American River. He finds lost treasures in the water and takes the items that are able to be identified and puts them on Facebook.

He's been able to track down owners of GoPros through shares.

"I found a couple of pictures and posted it on Facebook and I didn't know it at the time, within nine hours, one of the people had sent me a note," Bly said.

It's a passion for hunting he got from his father, Edwin Bly. He passed away last year.

He said the most interesting thing he's found in the water is with his dad.

"My father and I way back in the 1970s found an electric golf cart, probably joy riders and ran into the river, and we were able to pull it out," Bly said.

Bly described his dad as an avid diver who went out to the river everyday.

Instead of Facebook, his dad let people know what he found through newspapers.

"We've got this great picture of my father in 1973," Bly said. "A newspaper picture holding a wad of prescription glasses that he found one day."

For some of us, the American River may be the last place we would think of treasure hunting.

"If you're out here in the middle of the summer, it's active with human wildlife," Bly said.

However, many of the items he finds don't make it back to their owners. He's found sunglasses and even a boat that he's been having trouble getting a hold of through restrictions at the DMV.

At the end of every adventure, this proves to be a hobby he's sharing with his three boys as tribute to his dad.

"He was always thinking about the next place to find a treasure," Bly said. "Not the gold sunken ships type of stuff, but the common-sense things."

As a sign of good luck, Bly always goes out into the water with things he finds in the water, which includes his boat and snorkel.
