The Anacostia Watershed lies within the Chesapeake Bay drainage basin, and is one of the most urban watersheds within the basin. According to the Fish and Wildlife Service, the watershed spans over 175 square miles between Maryland and the District of Columbia and is considered by many to be one of the most degraded waterways in the United States. Watts Branch is a tributary stream of the Anacostia River, and flows into the Potomac River which eventually empties into the Chesapeake Bay. In 2010, several partnerships were formed to restore a section of the Watts Branch stream and riparian area. The restoration efforts were focused on a highly polluted 1.8 mile stretch of the stream, running from the border of Prince...

The Lower Truckee River originates in the Sierra Nevada and flows through public, private, and tribally owned lands, including 31 miles of the Pyramid Lake Paiute Tribe (PLPT) reservation, terminating in Pyramid Lake within the reservation. Once remarkably productive, a century of man-made changes have heavily degraded the river system, leaving it inundated with invasive weeds. Significant damage occurred as part of a 1960s flood control project, including river downcutting, depression of the groundwater table, and lowering of Pyramid Lake by as much as 81 vertical feet. By the 1970s, the river had lost roughly 90% of its forest canopy, 40% of its resident bird species, and had no resident Kooeyooe (also spelled...
For thousands of years, much of the San Luis Valley basin of south-central Colorado was made up of a series of lakes, marshes, and shallow playa basins that were integral to the lives of indigenous peoples. By the mid-1900s, the basins had dried up from the diversion of water sources for irrigation and became known as the “Dry Lakes.” In 1965, BLM began a series of wildlife habitat projects to restore some of the historic wetland characteristics and processes, and 9,600 acres of the former “Dry Lakes” area became known as Blanca Wetlands. BLM designated the Blanca Wetlands Area (BWA) as an “Area of Critical Environmental Concern” (ACEC) in 1991, due to its high importance for wildlife and recreational values. Today...

Migrating shorebirds and waterfowl are so dependent on the food supply and stopover estuary habitat in the lower Coquille River that Congress established Bandon Marsh National Wildlife Refuge (OR) in 1983. Through congressionally approved expansion, acquisition, and donation, the Refuge now encompasses 889 acres and is composed of two units: Bandon Marsh and Ni-les'tun (named by the Coquille Tribe and pronounced NYE-les-ton, which means People by the small fish dam). Historically, Ni-les’tun was a diverse tidal wetland like Bandon Marsh but was diked and drained for agricultural purposes beginning in the mid to late 1800s. Restoring 418 acres of the tidal marsh has required FWS and its many partners to collaborate...
