The Atchafalaya Floodway System
• 50,000 acres of the land is in-fee for public use.
• They also hope to have 33800 acres on purchase easements.
• To date they have approximately only
32,000acres.
• The fee-owned public areas will be opened for use.

• Mississippi River
• Atchafalaya river flows 226,760cfs with a sediment load of 88,223000 tons.
• Wax lake takes 38% of the river flow and
35% of the sediment.
• Lower Atchafalaya River
• Gulf of Mexico

• Some effects from the channeling are good.
• Increased sediment deposition
• Other effect are dead zones
• Stagnate water which has caused crawfish production to go down.

• In the Atchafalya Delta exposed land has increased from 10,000 acres to 19,000 acres in 1995.

• Plants such as duck potato vegetate the small islands (i.e. deltas) and provide excellent waterfowl habitat.
• The placement of sediment from dredging make land in these areas and that land is proving to be good mottled duck habitat for their colonial nesting.

• Older islands do move on though and stand of willow take hold and have shown to make great wading bird rookeries.
• Supplemental planting of oaks on these areas help to feed the rising deer population in these areas.

• 70 species of fish
• 100 different types of plants have been documented
• 200 species of birds identified
• 60 species of reptiles found

• It’s a growing delta system
• The wetlands located there are considered nearly stable. Wetland loss between
1932-1990 is only 3760 acres.

• Vital staging area for migratory birds
• Provide food and resources for their long flights.
• Breeding Bird Habitat
• One half the migratory species of North
America flyway use this area each year.
