Water level is low today, the stones had a bit of silt on them but not much. This site is also a RMI site, last month was amazing, this month wasnt as good but still better than normal. Olives x 6 Gammarus x 60 RMI score = 3 + damselfly x 1 , leeches x 2

Im now doing monthly RMI at this site, its better than last month because I wasnt so rushed, it takes ages as there is so much debris and mud. Cassed caddis x 7 Olive x 1 Gammarus x 690 RMI score = 5 + demoiselle x 1, worms x 4, hoglouse x 21 For comparison this is Hawkswood Olives x 6 Gammarus x 60 RMI score = 3 + damselfly x 1, leeches x 2

Loads of natural debris in the brook, hence why I wont RMI here.

Kyd Brook C.S.O by Kirsty Blackman
As you all know there is a CSO a little upstream from this monitoring site. I may have missed some as its been raining a lot recently but I have captured 4 discharges. 3/2/26 17:00 - 4/2/26 00:00 = 7hrs 11/2/26 15:45 - 16:15 = 30 mins 15/2/26 18: 00 - 19 :00 = 1hr 15/2/26 23:15 - 23:45 = 30 mins

Kyd Brook Hawkswood Estate by Kirsty Blackman
Water levels are slightly higher tham normal, but still not very high. Stones are clear. This site is also a RMI testing site, today was brilliant for this site. Cassed cadfis x 1 Blue winged olive x 1 Olives x 34 Gammarus x 157 RMI score = 7 which is so good for this site. + leeches x 9, hoglouse x 2, annelids ( worms) x 2 Very happy, this is even though there has been a lot of rain so who knows whats is being discharged into the brook via the SWOs.

Kyd Brook S.W.O upstream by Kirsty Blackman
The idiverde person who manages Crofton Woods ( a S.S.S.I protected woodland which is a london clay wet woodland containing many Oaks) for Bromley council wants to place beavers here eventually, citizen zoo have done a site visit but he hasnt asked the local community what they think. 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. Hence 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. Today 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. Gammarus x 130 Cassed caddis x 2 RMI score = 4 + 3x hoglouse, 10 x worms Hawkswood 7/2/26 Cassed caddis x 1 Blue winged olive x 1 Olives x 34 Gammarus x 157 RMI score = 7 amazing for this site, the best to date + 9x leeches, 2x hoglouse, 2x worms

Kyd Brook S.W.O upstream by Kirsty Blackman
It rained very heavily yesterday evening, this site is quiet a bit downstream from the CSO that was discharging into Kyd Brook yesterday evening for 4hours and 45minutes, the water monitoring results were good, which is a pleasant surprise. The water is faster than usual and higher, still not really high though as you can see by my boots in the atttached photo. You can even see the base of the brook in that same photo, which is very rare indeed and just shows how much rain there was.

Kyd Brook S.W.O downstream by Kirsty Blackman
Ive added the CSO discharge event photos just because it was discharging last night for 4hrs 45mins and even though this site is quiet a way downstream. The water was faster and higher than usual but still not terribly high. Even though the water had removed some of the natural debris before the SWO, it was not the case this side.

The heavy rain has cleaned the silt from the stones, the water was faster than normal and slightly higher.
