The purpose of this report is to describe the development of a coast wide monitoring plan for Louisiana with specific implementation recommendations for the Barataria Basin and Pontchartrain Region (Breton Sound, Pontchartrain and Mississippi River Delta basins). Version I of the report was produced in February 2015 and included only implementation recommendations for Barataria Basin. A presentation was given to state, federal, and non-governmental representatives in April 2015 to communicate the main findings of the report and to elicit feedback on the monitoring design and implementation strategy. As a result of the workshop and from comments received during the review of the report by CPRA, Version II of the report was produced to include additional data analysis, improved integration with existing monitoring efforts, and a conceptual diagram of the linkages between the human and natural systems. The design developed for Barataria was then expanded to the basins east of the Mississippi River. The implementation recommendations for the Breton Sound, Pontchartrain, and Mississippi River Delta basins are incorporated into this Version III of the report.
