The Barataria-Terrebonne National Estuary Program expects to find a wide variety of junk in Bayou Lafourche when the group does its annual cleanup along 106 miles of the waterway March 15.
A spokesman says past finds in sweeps of the bayou, which provides drinking water for communities along its banks, have included old toilets and underwear.
The Daily Comet reports the group is seeking volunteers for the cleanup.
Alma Robichaux, education coordinator for the group, says about 1,000 volunteers are needed to sweep the bayou from Donaldsonville to Leeville.
Prospective volunteers can reach Robichaux at 985-447-0868 or firstname.lastname@example.org.
