Freshwater Stories

Last October, specialists released 700 Russian sturgeon into the Danube River in Isaccea, Romania. The restocking project is part of a Danube-wide effort to revive wild sturgeon in the region.

In Cambodia, WWF sets its sights on keeping the lower Mekong River flowing free

By engaging with decision-makers and key players around the world, WWF works to keep dams from impeding free-flowing rivers while amplifying opportunities for sustainable energy-producing alternatives

Freshwater fish are vital for communities, economies, and ecoystems. But they are under increasing threat and need our help now more than ever.

Rivers are more than water; they’re the lifeblood of ecosystems. So when a river’s natural flow is impeded by a dam, biodiversity suffers.

As seasonal waters ebb and flow, the movements of elephants and other wildlife follow.

Keeping water flowing for people and wildlife in the Kavango-Zambezi Transfrontier Conservation Area will take action at every level. Here's what WWF is doing for it.

Twenty-one percent of the country's territory is now protected, including a vital free flowing river

In a significant step forward for nature and communities that depend on the mighty Mekong River, the Cambodian government has abandoned plans to build the Sambor hydropower dam and has put a 10-year moratorium on any new dams on the Mekong mainstem.

In Guatemala, thousands of people call the Teculutan and Pasabien watersheds home. Under the cover of iconic cloud forests, rivers flow down from the mountainous region called the Sierra de Las Minas; providing fresh water for nature and these communities, for drinking, hygiene and sanitation, agriculture, as well as for business operations and so much more.

In 2009, principal and teacher Marcia Novakc da Silva decided to join forces to start a community rainwater project, led by the organization Incra and supported by WWF. The work is one of  several projects for the recovery of the springs and water supply in region.

The sprawling Pantanal supports a wealth of wildlife, plants, and people. As pressures intensify in this ecosystem, multinational cooperation and a holistic strategy are key to a better way forward.

Development within the Pantanal must be managed sustainably. Today, community members across the region are working to conserve this essential landscape and their own way of life.

Mangroves are a vibrant part of coastal wetlands on five continents. Explore some of the most diverse coastal forests around the world.

Before the water treatment facility was built on Margarita Island, the 350 residents of the tiny Paraguayan community drank straight from the Paraguay River. Pollutants, dumped by fishermen, tourists and cargo ships, as well as farms and factories located along the river, made kids sick, and stained their clothes with mud.

In addition to being an environmental jewel, the Pantanal is also a tremendous resource for people. Collaboration is central to keeping the water flowing in the world's largest tropical wetland.

A day in the life of Carolina Alvarez, as she protects the Pantanal for wildlife and people, includes cleaning trails and monitoring wildlife like anacondas, jaguars, and caiman using camera traps.

In February, a group of researchers led by Field Museum scientist Lesley de Souza found six new catfish species—all with some pretty funky-looking snouts.

WWF is advocating that energy investors replace plans for hydropower dams in Cambodia with large-scale solar farms, which are more environmentally friendly and quicker to build.

In a major boost for communities and wildlife in the Luangwa river valley, the Zambian government halted plans to construct a mega hydropower dam across the river, safeguarding the diverse benefits it provides to people and nature.

More than 32,000 acres of the Mura River and its crucial floodplains in Austria were declared a “biosphere reserve”—a major step toward conserving one of the richest natural areas in Europe.

Only a little more than one-third of the world’s 246 longest rivers remain free-flowing, drastically reducing the diverse benefits that healthy rivers provide to people and nature everywhere, according to a new study by WWF and partners.

In March, WWF-Brazil led a group of 25 journalists, researchers, and celebrities on a five-day adventure that involved boating, driving, walking along the Paraguay Rivera and through the Pantanal.

A pair of mega dams in construction on the Santa Cruz river’s banks could flood more than 135 square miles of the surrounding region--an area almost twice as big as Buenos Aires--and transform Argentina’s last free-flowing glacial river into a series of brackish pools.
