The City Council’s initiative to enhance our chalk streams was put into practice this week as 20 tonnes of gravel was added to Cherry Hinton Brook. Added with care and consideration by a group of local volunteers, the aim being to funnel and guide the water as it travels downstream to increase flow and oxygen while also creating areas of slack water and deeper pools. This diversity in conditions improves the overall health and species count in the stream. Plus it’s lots of fun for the humans to make! If you want to check out these changes, the section worked on is just behind Cherry Hinton Hall Park, alongside the allotments.
