France 24 reports that the last draining in 2001 also revealed strange debris including more bicycles, bathtubs and ammunition from World War I.
More than 24 million gallons of water were slowly drained from the canal in the massive clean-up project which takes place every 12-14 years and cost approximately $10.2 million to complete.
"It's necessary to dredge the canal, repair its walls and renovate the locks," Eau de Paris president Célia Blauel said.
Teams of fisherman will collect the canal's wildlife as the area is drained. When draining is complete the canal will remain empty for about three months.
