Even though the water levels are normally very low on this section of Kyd Brook.  The water levels do rise when there is rain due to the CSO and 3 x SWOs discharging and also the woods drain into the Brook, but it still doesnt overflow unless there is an obstruction.  To introduce Beavers, which there is only enough space for 6-8 beavers a large amount of fencing would have to be installed,  which would mean digging the woodland putting in posts and installing the fencing 4inches deep into the soil, which would disturb the natural bacteria and could also compress the soil.  We have been told that the trees can be protected but others question this. Even though there has been no public consultation, he wants to instal attenuation pools, hoping to improve water quality due to the pollution from the CSO, but the major pollution if using ammonia would be the Ember close SWO, and the beavers would be upstream from here. Phosphate levels are relatively high and could potentially lead to algea forming, this is not the case and never has been so far. He is also carrying out riverfly tests but is not carrying them out to the RMI standard.  I have quieried this via email but he hasnt replied and have been told he will not reply.\r\nHence why I am going to carry out RMI at this site, admittedly it would have been better to carry out the testing downstream at this site but it is darker and has a lot more debris and muddier. I have to give it a chance afterall, Brain and I also RMI monitor at Hawkswood a lot further downstream, so I will also add these here for a comparison.\r\nToday I was rushing, there was lots of debris and very muddy so I have probably missed a few.   Water level at its deepest was 30cm, which is really deep for this brook here.\r\nGammarus           x 130\r\nCassed caddis      x 2\r\nRMI score         = 4\r\n+ 3x hoglouse, 10 x
