Tidal Freshwater Swamp at High Tide
Areas like this tidal freshwater swamp, along the Pocomoke River in Maryland, provide important ecosystem services including improving water quality by trapping watershed sediment before it reaches the Chesapeake Bay. However, a sediment shadow along tidal rivers may limit their resilience to the impacts of sea level rise.

A Rainbow Trout Rests Among Cobble Substrate in Panther Creek
A Rainbow Trout Rests Among Cobble Substrate in Panther CreekA rainbow trout rests among cobble substrate in Panther Creek downstream of Big Deer Creek, central Idaho. Panther Creek was severely damaged by heavy metals released from mining and milling activities at the former Blackbird Mine, and water quality in this section of the stream was acutely lethal to fish as late as 1985.
