"These Are the 10 Most Endangered Rivers in the USA"

"Environmental group American Rivers released its annual list of the USA's top 10 'most endangered' rivers Tuesday, and this year, the top "dishonor" goes to the Big Sunflower River, a tributary of the Mississippi River in the South.

The river is listed as most endangered, American Rivers said, because of the proposed U.S. Army Corps of Engineers Yazoo Pumps project that aims to curb flooding in Mississippi's delta region by draining thousands of acres of wetlands.

Calling it 'one of the most environmentally damaging projects ever proposed by the Corps,' American Rivers said the plan threatens the river and 200,000 acres of surrounding wetlands, home to more than 450 species of fish and wildlife."
