The large weir at Darley Abbey, Derby is no longer an issue for fish wanting to explore further upstream due to the successful construction of the largest fishpass implemented by a Rivers Trust in the UK. The two flight larinier pass is 3 meters wide by approximately 30 meters long overall and dissects a natural island located between the two large weirs at Darley Abbey.

Fishtek carried out the design of the fishpass and have project managed the construction on behalf of the Trent Rivers Trust.

Although the contractor involved with the build has produced an outstanding fishpass, the construction phase didn’t go without incident. During excavation of the island the watching archaeologist identified some timber piling and stonework thought to be the remains of a leat feeding the nearby Abbey way back when, laboratory work on the finding continues.
