Porter Brook - Part of the Deculverting Process

Picking up from my previous post of the in-channel habitat creation - here are just a few photos to give an impression of the site's previous states.

This gives a bit more of an idea of how little of the river was allowed to see the open air until pretty recently. Sheffield City Council have been steadily working to expose this buried watercourse...

















So, a great deal of credit deserves to go to Sheffield City Council and their planning/landscape people. I will be putting together video of this project (which should hopefully include some drone footage to give a good overall impression).

Watch this space...

Porter Brook - Channel Habitat Improvement in De-Culverted City Centre Stream

There will be more pictures and video to come to document this bold project by Sheffield City Council to uncover a section of stream that used to live beneath a factory floor. They are in the process of creating a "pocket park" that will provide new flood-water storage (when the rivers are in spate) and an improved public park amenity (when the rivers are calm).

The pocket park itself will be excavated out from the current high ground level (and a major construction project is underway at the moment to achieve this).

The Wild Trout Trust were brought in to design in-channel features and riverbed morphology that would maxmise the improvements for the ecology of the stream - including for the prospects of a small and fragmented native population of wild brown trout.
