Apparently, Owl Bayou once flowed from the southwestern corner of today’s Joyce Wildlife Management Area on its way to North Pass. The intervening construction of the railroad, Hammond Highway, US 51 and I-55, with their attendant roadbeds and canals, obliterated the middle stretch of this channel and now occupy about a mile between the upper Owl Bayou drainage pattern and the lower part of the bayou where it flows into North Pass and Lake Maurepas.
The Friends of the Manchac Greenway worked with Tangipahoa Parish Government, Entergy Corp. and others to clean up and restore a short piece of the old Hammond Highway next to the bayou that is used by fishermen.
