Fish Pass, River Deerness, Esh Winning ,Co Durham
Broadgate weir was the most difficult section for fish to pass on the river Deerness. The Wear River trust asked us the construct a 35m bypass channel. Before the work could take place substantial bank stabilisation work was required to the upstream section of the river, by driving long larch logs into the bank, back filling with willow brash and soil. Once this was completed we could start work on the bypass channel. The channel consisted of 12 steps and 11 resting pools. Using locally sourced limestone rock armour for the construction of the channel and on river banks we used coir matting to speed up the vegetation process. Now the work is completed all species of fish can travel up the new channel.
