Why an atlas and guide?

Rivers and canals are wonderful places to be.

We believe the more you understand them, the more you can enjoy them. That leads to a deeper care for them and a thirst for more knowledge.

Atlas and guide

One river. The whole story.

EveryRiver brings fragmented knowledge together to tell the whole story of a river or canal. It combines information from public authorities with community knowledge and guidance. It is designed for laptop, PC and mobile phones.

01

Places and landscapes

Follow the river and discover its origins in the hills and ground beneath you. Float through the natural beauty of its landscapes. See the power and character of the river change as it is fed by its tributaries.

02

Wildlife and habitats

Explore species, habitats and nature observations connected to each stretch of river.

03

History and culture

Understand how our lives, buildings, events and language have been shaped by the water.

04

Access and enjoyment

Give and receive guidance on walking, paddling, boating, swimming, fishing and just idly spending time by the river.

05

Live conditions

See river levels, flows, rainfall, tides, weather, water quality and other changing conditions.

06

Sources and shared knowledge

Learn more about rivers and canals and give others the benefit of your knowledge. Add your favourite books, explain how things work, verify, update, challenge and edit, for the benefit of future generations.

Knowledge connected

Bringing the fragments together.

River and canal knowledge is scattered across maps, datasets, encyclopaedias, field observations and local experience. EveryRiver brings them to you as one, so you can easily understand and enjoy them more.

Information from Wikipedia, Wiktionary and iNaturalist is included within the atlas and guide.

Sources and provenance remain visible, so knowledge can be checked, understood and improved.
