The urban reef at Isla Verde supports various species of protected corals, sea turtles, and crustaceans, as well as many Caribbean fish. It also protects the International Airport and numerous homes and resorts on the coast.

RestoreNet locations are testing commonly used restoration techniques, including pitting, mulching, and above-ground micro sites. Here, pits have filled with water, illustrating how this technique increases soil moisture by capturing rainwater.

USGS staff survey the Mill River near the former Hopewell Mills Dam site in Taunton, Massachusetts. Surveys at the dam-removal and culvert-retrofit sites provided topographic and bathymetric data for hydraulic models developed for the study.

In September 2011, the largest dam removal project in U.S. history began.
Two dams built on the Elwha River in the early 1900s created two reservoirs in northwestern Washington. They also greatly reduced the amount of sediment flowing to the river’s delta and blocked salmon migration upstream into Olympic National Park.
