“Our other brother drowned back in 2016 and this was near the Rainbow Bridge,” she told KTVT-TV in Sacramento. “This past Saturday is when Melino drowned as well.”

Captain Brian Gonsalves with the Sacramento Metro Fire Department says the water is deceptively low. In addition, branches, trees, and debris that have been underwater for years are now surfacing, which swimmers can get caught in.

The levels are also impacting rescue operations.

“It’s so shallow that we are having a hard time putting in our water rescue boats,” he said.

Josh West has been swimming in the river for years. “There’s a lot of underestimation that occurs, and when there is lower water, sometimes it’s the debris,” he said.

As for Melino’s family, they are now planning his funeral instead of a high school graduation celebration.

“People would know him as a gentle giant,” Poliana said, adding she will be accepting his diploma in her brother’s honor. “He had plans after high school — he wanted to join the military.”
