Response Location: United States, Lancaster, Pennsylvania

Scientists have transformed a stream in Pennsylvania into a marshy waterway because of a restoration project that removed 22,000 tons of legacy sediment built up by colonial-era farming and logging. After removing meters of mud from the banks of Big Spring Run, native vegetation returned, which resulted in the storage of organic carbon tripling in the restored area and the amount of key pollutants in the stream sharply dropping. Similar restoration projects are being tried in other mid-Atlantic states.

While this technique doesn’t always work during major flooding events, traditional flood control strategies can be more harmful and actually worsen flooding.
