The bird was found stranded at a dam along the lake "at least 15 or 20 feet out of reach," according to the Netcong Police Department and St. Hubert's Animal Welfare Center in Madison.
Animal control officers worked for several hours to rescue the swan, which was "in a very difficult location under a bridge on the dam," St. Hubert's said.
"The rushing water and slippery surface made the rescue all the more challenging."
The bird was then taken to the Raptor Trust for treatment and will be released in a safe location close to where it was found once fully healed, authorities said.
The Netcong Fire Dept. also assisted with the rescue, police said.
