The Tennessee Valley Authority was founded in 1933 to modernize agricultural communities of the U.S. Southeast through the construction of dams, river diversions and power infrastructure projects along the region’s great rivers. These drastic changes to the rivers and their watersheds set off a cascade of effects to the riverine ecosystems. The species depicted here – the cerulean warbler, blue masked darter, little blue heron and great egret – are some of the many species whose habitat, range and populations have been significantly impacted.

The Puget Sound southern resident orcas rely on Chinook salmon as their primary prey, feeding on them year round. In large part due to four migration-blocking dams on the lower Snake River, wild Chinook are at 10% of their historic numbers, threatening the survival of these 74 orcas. Further upstream, where the reservoirs behind the dams have flooded the river’s shorelines, birds such as the American goldfinch have lost nesting grounds and habitat. A proposal to remove the dams has moved through the courts, advancing a contentious legal battle that involves conservationists, public agencies, Native American tribes, fishing interests and others.

A dam boom is underway in the Brazilian Amazon, significantly altering river flows, hydrology and chemistry. Hundreds of new dams are threatening the survival of many animal species, and impacting the indigenous and river communities that depend on the rivers for food. The Black Skimmer, pictured here, has the distinction of being the only bird whose lower mandible is longer than the upper – it uses it to skim the surface of the water and scoop up small fish. Its nesting sites are disrupted by dams. The Crenicichla Johanna is an ornamental fish, which, as part of the larger ecosystem, is also affected by the dams.

The giant catfish depicted here, Brachyplatystoma rousseaxuii, has the longest reproductive migration of any freshwater fish, traveling from the mouth of the Amazon 3,400 miles to the spawning areas in the western tributaries of the Amazon. Newly constructed dams, such as the Santo Antonio and Jirau, on the Madeira River, are greatly impacting those migrations.

The Sacramento–San Joaquin River Delta in California has undergone massive changes over the last eight decades from dams and other alterations that have changed these two rivers’ natural course, flow and hydrology. The Green Sturgeon and Smith's blue butterfly are endemic to these rivers and are just two of the many species whose habitat, range and population have been affected by dams in the region.

The Sacramento–San Joaquin River Delta in California has undergone massive changes over the last eight decades from dams and other alterations that have changed these two rivers’ natural course, flow and hydrology. Chinook salmon, pictured here, have been in the headlines since the early 2000s because of plummeting population and spawning counts, partly due to dams along the rivers.

The Boto, a pink river dolphin endemic to the Amazon river and its tributaries, feeds on about 50 species of fish and is an important part of the flooded forest ecosystem. It is affected by dams' impact on oxygen content of the water, and on the general impact on seasonal flooding levels. The giant catfish depicted here, Brachyplatystoma rousseaxuii, has the longest reproductive migration of any freshwater fish, traveling from the mouth of the Amazon 3,400 miles to the spawning areas in the western tributaries of the Amazon. Newly constructed dams, such as the Santo Antonio and Jirau, on the Madeira River, are impacting those migrations.

Depicted here are a white-tailed deer and red-winged blackbirds. The reference photo used for the deer was taken by George Shiras, credited as the father of wildlife photography, who was the first to use camera traps and flash photography when photographing animals.

The Sacramento–San Joaquin River Delta in California has undergone massive changes over the last eight decades from dams and other alterations that have changed these two rivers’ natural course, flow and hydrology. The Delta Smelt and the California Least Tern, both pictured here, are two species that are imperiled as a result of damming and river diversion upstream from the Delta.
