This in turn will benefit fauna dependent on marginal and aquatic habitats and fish passage will be unrestricted. This length of river is largely owned by the EA and was straightened to accommodate the M11 and North Circular improvements. The channel was over-sized channel with flood embankments on both sides set back a few metres from the “first stage” riverbanks. The weir may have been installed to reduce the gradient. These channel modifications have resulted in a degraded stretch river in terms of both ecology and geomorphology.
