Which wetland is known to be the largest freshwater wetland in the U.S.?

The Florida Everglades is the largest freshwater wetland in the United States, covering approximately 1.5 million acres. This unique ecosystem is characterized by slow-moving waters and supports a diverse array of wildlife, including numerous threatened and endangered species.

The Everglades play a crucial role in regional water management by acting as a natural filter for water flowing into southern Florida, and it contributes significantly to the water supply. Its vast expanse and complex interactions between water, soil, and vegetation make it a vital ecological region.

The other choices, while notable wetlands, do not compare in size to the Florida Everglades. The Great Dismal Swamp is a large wetland located in Virginia and North Carolina, but it is smaller than the Everglades. The Okefenokee Swamp, found on the border of Georgia and Florida, also ranks as a significant wetland but is not as extensive. Caddo Lake, straddling the Texas-Louisiana border, is known for its unique cypress-trees and rich biodiversity but is much smaller than the Everglades. Understanding the vastness and ecological importance of the Florida Everglades highlights its designation as the largest freshwater wetland in the U.S.
