Protecting and improving the rivers and waterways of Calderdale, Kirklees, and Wakefield. For people, for wildlife, and for the communities who love them.
We're your local Rivers Trust. A registered charity working across Calderdale, Kirklees, and Wakefield to protect, restore, and celebrate the rivers at the heart of this landscape.
From the River Calder to the Colne, the Holme, and every beck and brook in between, we work with local communities, volunteers, and partners to make our waterways healthier, wilder, and more resilient. We're part of a network of over 60 Rivers Trusts across the UK and Ireland, all united by a single goal: rivers that people and wildlife can thrive alongside.
Your donation goes directly into protecting our rivers. Every contribution counts.

Improving water stewardship, water quality, and biodiversity across the catchment.
The rivers of Calderdale have shaped everything. The landscape, the naming of places, the towns, and the industry that built the region. The Calder's story stretches back 310 million years, from ancient tropical rainforest to the wool trade, the canal age, and the floods that have tested this valley time and again.
It's a history worth exploring, and a river worth protecting.

Our sustainable approach
At Calder Rivers Trust, we believe that sustainable design isn’t just a choice, it is an obligation. The health of our natural world is at the heart of everything we do, and that includes our digital footprint. Our approach to building our website reflects our commitment to a world where both our rivers and our climate can thrive.
By using compressed images, simplified code, and optimised content, we ensure our online presence aligns with our mission to protect nature. Through these practices, we have kept our environmental impact to a minimum.
Impact: Our homepage produces just 0.12g of CO₂ per page load.
Performance: This makes our site cleaner than 71% of all web pages tested globally.
Measurement: We track our footprint using Website Carbon, which calculates footprints based on data transfer, energy use, and the carbon intensity of the electricity used.
