History

The very first World Rivers Day was celebrated in 2005 and since then it has been gaining in popularity with many events being organized around the world.

In this same year, the United Nations also launched its Water for Life Decade, with the aim of increasing the awareness of the need for taking better care of the world’s waters.

You might be wondering why we need a World Rivers Day as everyone is already aware of numerous rivers around the world. That’s true; but what some people aren’t aware of is just how under threat some of them are.

Human activity regularly pollutes and damages many of the world’s important waterways, which is dangerous for the people who regularly use the rivers as a source of water and transport and for the ecosystems that could be living in them.

The main aim of World Rivers Day is to ensure that everyone is aware of the importance of river stewardship and that we all do what we can to limit the threats that could potentially endanger our rivers.

So, you are probably wondering how this all started. Well, it began with the Water for Life Decade, launched by the United Nations in 2005.

This was created to improve awareness regarding the need to better care for our water resources. This ultimately led to World Rivers Day being created. This happened in response to a proposal initiated by Mark Angelo, a worldwide renowned river advocate.

How to celebrate

Participate in a World Rivers Day Event

You might be able to find a local event, such as a litter clean or a beach litter pick. There are loads of different events that aim to get people out and about being active in helping to improve local rivers. Some events even focus on the wildlife that lives in our rivers. One example is to take part in a fish enhancement program that some local river organizations might be running near you.

Celebrate a Local River

It’s also a really good excuse to celebrate your local river as well. For instance, some people decide to take to the water to go sailing, kayaking, or canoeing. No matter how you want to enjoy the rivers, there is really no better day to enjoy them than on World Rivers Day! You will be able to really appreciate what needs to go into keeping them clean and helping the local wildlife enjoy healthy habitats.

Plan a World Rivers Day Event

One of the ways that you can celebrate World Rivers Day is by planning an event. It is a good idea to select an event that is going to use local resources and expertise, and which will address local issues, customs, and interest. Events on these days can range from a single event, such as a clean-up of a creek section or a paddle down a creek to a big local festival with a number of different features and events going on. It is a good idea to look to involve different organizations and groups from the community so that you gain participation and local support. Get in touch with local businesses, hospital foundations, the government, and local schools. You can also contact local interest groups as well, including the likes of environmental groups, recycling societies, heritage societies, music societies, art societies, daycares, paddlers, and birders. By getting help from a number of different groups of people, you are going to be able to diversify your event. This means that it is going to turn into a celebration of your local environment and the connections your community has with its rivers.

Get World Rivers Day Updates

You can also head to the World Rivers Day website and sign-up for updates and alerts regarding the different events that are going on around the world. You never know, there may be something that is planned for your local area on this date. No matter how you choose to spend the next World Rivers Day, we are sure that it will help you appreciate your local waterway a lot more than what you might do right now. If everyone did, imagine how clean our rivers could be!

FAQ

Which river has changed course the most times in history?

The Kosi River in India and Nepal is known as the “Sorrow of Bihar” because it has changed course dramatically over centuries. Its shifting channels have displaced villages and altered landscapes. Scientists have recorded at least 12 major course changes in the past 250 years. The river moves due to heavy monsoons and sediment deposits, creating new paths and unexpectedly flooding areas. Some researchers compare it to the Mississippi River, which also historically shifted course before levees controlled its movement.

What is the longest underground river in the world?

The Puerto Princesa Subterranean River in the Philippines stretches 8.2 km (5 miles) beneath limestone caves. It flows directly into the sea, making it unique among underground rivers. Visitors can explore parts of it by boat, seeing bats, unique rock formations, and marine life. It is also a UNESCO World Heritage Site. Some believe it extends even further beyond mapped sections.

Why do some rivers mysteriously disappear?

Some rivers vanish due to geological activity. The Sambhar Lake River in India disappears into the desert, reappearing elsewhere. The Lost River in Idaho flows underground for miles before resurfacing. Other rivers, like Mexico’s Atoyac River, have been swallowed by sinkholes. Climate change and human interference also cause rivers to dry up permanently, as seen with the Colorado River delta, which no longer reaches the sea.

What is the strangest thing ever found in a river?

People have discovered bizarre items in rivers, including ancient Viking swords, 14th-century gold coins, and even woolly mammoth bones. In 2015, a fisherman in the Czech Republic found a 3,000-year-old Bronze Age sword in the Vltava River. In 2021, archaeologists uncovered a perfectly preserved Roman chariot from the 2nd century AD buried near a river in Croatia.

Which river has the most dangerous wildlife?

The Zambezi River in Africa is home to crocodiles, hippos, and bull sharks. Hippos, despite their calm appearance, kill more humans than any other large African animal. Nile crocodiles are aggressive predators, known for dragging prey underwater. Surprisingly, bull sharks have been found far inland in the river due to their ability to survive in freshwater.

What’s the weirdest river-related law?

In England, by ancient law, any unmarked swan swimming in the Thames River technically belongs to the British monarchy. The annual Swan Upping ceremony counts and tags these birds for conservation. In the U.S., some states have strict laws about fishing in rivers—fishing with your hands (called noodling) is illegal in several states because it threatens fish populations.

Which river has the strangest color?

The Rio Tinto in Spain runs blood red due to its high iron and sulfur content. The acidic water supports almost no life, resembling conditions on Mars. NASA even studied the river to understand alien environments. Meanwhile, Canada’s Milk River appears milky due to fine clay particles suspended in the water.

Has a river ever caught fire?

Yes! The Cuyahoga River in Ohio famously caught fire at least 13 times due to pollution. The most famous fire, in 1969, helped spark the U.S. environmental movement, leading to the Clean Water Act. The fire was caused by oil slicks and industrial waste floating on the river. Today, the river has recovered significantly.

What’s the strangest use of a river in history?

During World War II, British forces floated fake corpses with false intelligence documents down rivers to trick the Nazis. One famous case, Operation Mincemeat, involved planting a corpse with misleading papers in a river, fooling German spies into believing an attack would occur in Greece rather than Sicily.

What’s the only river that flows both ways?

The St. Johns River in Florida flows north most of the time but can reverse due to tides and storms. It’s one of the few major rivers affected by ocean tides, causing unusual backflow. The Amazon River also experiences a temporary reversal during extreme flooding.
