Diversion Resources

Answering 10 Fundamental Questions About the Mississippi River Delta: What are the economic impacts of maintaining the status quo? How will restoration affect communities, fisheries, and navigation? Will sea level rise and subsidence negate our efforts? This paper systematically answers these and other questions. The research reveals considerable consensus within and across scientific disciplines about how the Mississippi River Delta functions and what actions must be taken to ensure long term sustainability.

“Assessment of ‘Lessons Learned’ from the Operations of Existing Freshwater Diversions in South Louisiana”: In 2011, a report was commissioned by CPRA documenting Lessons Learned from existing river diversion projects in Louisiana. A key component of this assessment was to examine the available data, literature, and reports specifically focusing on four (4) primary areas: the effects of diversions on coastal soils, vegetation, wildlife, and fisheries. A comprehensive list of approximately 1,272 relevant references was assembled and includes a mix of traditional, peer- reviewed literature (white literature), as well as agency reports, conferences, and meeting proceedings (grey literature). The linked bibliographies contain the references for A) soils; B) vegetation; C) wildlife, and; D) fisheries.

Diversion Project Fact Sheets: These fact sheets are intended to provided general information on diversion projects included in the 2012 Coastal Master Plan. Information about opportunities for public involvement associated with each project is also included.

“Myrtle Grove Delta Building Diversion Modeling Effort in Support of the LCA Medium Diversion at Myrtle Grove with Dedicated Dredging Project”: Data Collection, Preliminary Design, and Modeling Initiative.

Expert Panel on Diversion Planning and Implementation: CPRA requested the Water Institute of the Gulf to convene the Expert Panel on Diversion Planning and Implementation (the Panel) to provide independent guidance on addressing scientific uncertainties, implementation, and operation of the diversions included in Louisiana’s Comprehensive Master Plan for a Sustainable Coast. The Panel’s official charge is to provide technical input, review, and guidance to CPRA as plans are developed and refined for diverting freshwater and sediment from the Mississippi and Atchafalaya rivers into adjacent estuarine basins to build, maintain, and sustain coastal wetlands.
