Regional Ecosystem Strategies: Region 3
Restore Swamps
1	Improve hydrology and drainage in the Verret Subbasin
Restore/Sustain Wetlands
2	Maximize land building in Atchafalaya Bay
3	Lower water levels in the Upper Penchant marshes
4	Increase transfer of Atchafalaya water to lower Penchant tidal marshes
5	Enhance Atchafalaya Influence to Central Terrebonne Marshes (Bayou Dularge to Bayou Terrebonne)
6	Stabilize banks of navigation channels for water conveyance and erosion control
7	Dedicated delivery of sediment for marsh building by any means feasible
	e.g. deliver sand from offshore or the river to build marsh in Timbalier Bay area
8	Construct large conveyance channel from the Mississippi River parallel to Bayou Lafourche to divert up to 100,000 cfs to create a delta lobe in upper Timbalier Subbasin, provided that any project related navigation feature not impede or interfere with the land building capacity of the channel.
9	Establish multi-purpose hydrologic control of HNC (freshwater and sediment distribution, salinity control, hurricane protection, and navigation)
Protect Bay/Lake Shorelines
10	Maintain shoreline integrity and stabilize critical areas of Teche/Vermilion Bay Systems including the Gulf Shorelines (bay/lake/gulf)
11	Maintain shoreline integrity in Caillou, Terrebonne and Timbalier Bays
12	Restore and maintain the Isles Dernieres and Timbalier Barrier Island chains
Special Concerns and Opportunities
Resolve Salinity and Turbidity Problem in Bays
13	Optimize GIWW flows into marshes and minimize direct flow into bays.
14	Maintain Vermilion, East and West Cote Blanche Bays as brackish
