Project summary

Edit project overview to modify the project summary.

The River Calder Improvement Project, led by the Ribble Catchment Conservation Trust (RCCT), aim to ease the passage of fish species (specifically trout) and encourage upstream migration whilst improving the riverine habitat as a whole. This was achieved by the lowering of existing weirs, fish pass installation and more general habitat enhancement.
