Preface -- S. Jeffress Williams
Lake Pontchartrain is the largest estuary in southern Louisiana. It is an important recreational, commercial and environmental resource for New Orleans and southeastern Louisiana. This publication is part of a five-year, cooperative program led by USGS on the geological framework of the Lake Pontchartrain Basin.
This presentation has two parts. One part provides new scientific research results and documentation. This includes a preliminary release of a comprehensive database and report on bottom sediments from Lake Pontchartrain and surrounding waterways. The second part provides background information on the area for a wide circle of users. This is highlighted by an in-depth school curriculum guide to environmental education based on Lake Pontchartrain.
