Notes

The water level is low , there is lots of debris and silt on the base and stones are only visible in places. The water flow is constant but slightly slower than normal. There are just so many gammarus, its unbelievable, you can see them from the bank as the water is so low and even though the turbidity was 75, i think its scewered because the water level is low meaning you are disturbing the base which is covered in silt/ debris. I did try getting a photo of the gammarus swimming in the water, there is a photo and you need imagination to see it. Also, note the silt in my tray whilst riverfly monitoring, see photo. On a brighter note, on this section of the brook, whilst walking in the afternoon, it is full of beautiful blue and banded demoiselles, there are more on this section than the othet,( East Kyd Brook), literally loads. I have added some pics, i know its not from today but relevant as ive found demoiselle nymphs on 2 occasions whilst riverfly monitoring this section, plus it peoves that somehiw the water is clean enough to support them, hopefully in abundance along the brook but also there is the food for them. These pics were yesterday around 3pm, further upstream, where you will also notice there is lots of silt on the stones. Todays riverfly monitoring Gammarus x 586 RMI score = 3
