Pre- and post-dike removal at Billy Frank Jr. Nisqually National Wildlife Refuge

A 19th century dike (first image) cut the estuary at Billy Frank Jr. Nisqually National Wildlife Refuge off from tidal flow, and it eventually turned the landscape into a freshwater wetland, but the removal of the dike in 2009 has helped return the landscape back to its baseline condition as an estuary rich with biodiversity.
