Riverfly Monitoring

Every month, local volunteers conduct Riverfly Monitoring on the Upper Lea.  Their sampling technique involves a 3-minute kick sample of the river bed, and identification and counting of the aquatic invertebrates caught.  This gives a good indication of water quality and can alert authorities to any recent pollution incidents.  To find out more about Riverfly monitoring, or to get involved, please click here.
