Increased Flood Storage

Wetlands associated with rivers and lakes capture and retain water, reducing the duration and severity of floods. Inland wetlands intercept surface flow and slow it down, reducing the potential for floods and minimizing drought.

A recent study estimated that one acre of wetland can store over 1.5 million gallons of flood water. The bottomland hardwood wetlands along the Mississippi River once stored at least 60 days of floodwater but now only have capacity for 12 days storage because most have been filled or drained. The impact of the loss of flood water storage along the Mississippi was evident when floods in 1993 caused $12-$16 billion in damages, and yearly damages are estimated at $3.5 billion. Coastal wetlands in Louisiana have been valued at over $1,900 per acre for their storm protection functions alone!
