2. Riverfly Monitoring on the Middle Lea
Themes: Water quality; Public engagement
- Reduce chemical pollution
- Improve public engagement with the river
This project will establish a new Riverfly Monitoring Group along the Middle Lea.
Riverfly monitoring is a national scheme whereby local volunteers are trained in how to sample for an identify a range of freshwater invertebrates. Every month, pairs of volunteers will monitor the same site on their local river, building up a picture of the river's health and generating a score for the river each month. If this score drops below a certain 'trigger level', it indicates there has been a pollution event and the Environment Agency will come and investigate.
Riverfly Monitoring is often described as a 'neighbourhood watch scheme for rivers'.
On the Middle Lea, the next steps in the riverfly monitoring scheme will be to work with the Environment Agency to agree up on which areas will be established as sampling sites. Then, monthly sampling can take place to determine which invertebrates are present in the river, and in what quantitites.
