? The flow pattern in the wetlands was unusual. There was no flow through the outlet box in the rock weir west of the lower pond (site 5), but 27 L/min flowing out (at Regent street). Water was flowing in, through the box in the rock weir west of the first pond (site 4). This pattern may indicate leakage into the bypass pipe. ? We have modified our invertebrates sampling technique and the stream condition chart, in line with Waterwatch Training and Refresher sessions that 3 of the team have recently attended. Unusually, we found a caddisfly larva (very sensitive to water quality) in the Fiander arm. The Fiander arm was classed as fair, but the Crosby arm was classed as poor.
