Before the new year, we installed soil moisture sensors in the Upper Calder as part of our aeration project.

Funded by the Environment Agency & Calderdale Council, the data will help us measure infiltration & reduced run-off to support natural flood management.

In 2025, our Fluvial Geomorphologist, Adam, has undertaken a huge amount of Modular River Physical Surveys (MoRPh) to assess the physical habitat and overall condition of rivers. He's completed 93 surveys, covering 11.5km of river. A huge thanks to all the volunteers who helped!

Working with the farmer, landowner & a wetland engineer, we’ve created a new wetland system that fits the landscape & delivers big benefits — improving water quality, boosting biodiversity, & helping build resilience to drought & flood. Monitoring is underway as it settles in!

[Calder Rivers Trust @RiverCalder]

We regularly work with farmers and landowners, aiming to make our catchment resilient to both flood and drought. Our latest project, funded by @Calderdale and @EnvAgency, has aerated 140ha of land in Calderdale to improve infiltration and soil health.

[Calder Rivers Trust @RiverCalder]

We’re working with @Calderdale @KirkleesCouncil @EpiksK @moorsforfuture to co-design a 20-year Landscape Recovery plan. Using baseline habitat data & mapping, we’re supporting sustainable farming, nature recovery & catchment resilience. More to come as the project develops! 🌿
