The Calder Catchment Partnership brings together local people, organisations, and authorities to work towards a healthier and more resilient water environment across the Calder, Colne, and Holme catchments.
Calder Rivers Trust has hosted the partnership since 2019, building on a decade of collaborative catchment work that began with the Aire and Calder Catchment Partnership in 2012.
The partnership includes the Environment Agency, Yorkshire Water, local authorities, private landowners, charitable organisations, and community interest groups. All working together with one goal in mind: To improve the rivers at the heart of this landscape.
Co-ordinate
Share expertise and co-ordinate activities across the Calder catchment, facilitating improvements that benefit the landscape, people, and wildlife.
Collaborate
Bring partners together to identify multi-benefit projects, secure funding, and support improvement of the Calder catchment.
Perform
Set clear targets for the partnership and monitor progress against them and the national success measures.
Working alongside the Environment Agency, Yorkshire Water, local authorities, landowners, and community groups, the partnership aims to improve water stewardship, water quality, and biodiversity across the catchment.
We work to reconnect communities with their rivers, realising their economic and cultural value, and to support education and engagement with our waterways.


The Calder catchment ranges from the heights of the South Pennines to low-lying floodplains, encompassing an extensive canal network and home to around one million people.
The catchment is divided into four operational areas, each with its own distinct characteristics and pressures: Upper Calder, Middle Calder, Lower Calder, and Colne and Holme.
