This involves sampling the river monthly in order to look for a number of invertebrate creatures which are known to be good biological indicators of river quality.
Our results help to
- protect the water quality of our rivers
- further the understanding of river fly populations
- and actively conserve river fly habitats.
There is great excitement and satisfaction to be found in finding and identifying the larvae of caddisflies, mayflies, olives, and even sometimes stoneflies, many well known to anglers.
We have an enthusiastic team of river fly monitors who sample at 9 sites along the River Beane, from Walkern to Hertford.
