DESCRIPTION AND LOCATION

EGCP

These are generally small to medium sized streams in

southwestern Mississippi which drain into Lake Ponchartrain.

The lower portions of the larger streams lie in Louisiana.

CONDITION AND CONSERVATION STATUS

Streams in this drainage have been impacted by localized

channelization and construction of small impoundments.

Because of the relatively low conservation ranking of these

streams, they are apparently secure in the state.
