VOLUNTEERS MONITOR WATER QUALITY ACROSS THE ESK CATCHMENT

Riverfly Monitoring stems from the Angler's Riverfly Monitoring Initiative set up by the Riverfly Partnership. Trained volunteers are monitoring over 30 sites across the Esk catchment to assess water quality and alert YERT of any pollution or other incidents.

In the Esk catchment volunteers are allocated a site which they sample once a month from May to October each year (to avoid disturbing spawning fish). A three minute kick sample (to disturb the river bed and overhanging vegetation) and a one minute stone search is carried out. The sample is then cleaned using river water and put into a tray to settle. Key river invertebrate groups that are indicators of good water quality are identified and counted. These results are entered onto the Riverfly Partnership database and any results that vary from the norm are highlighted immediately by volunteers, allowing YERT to act quickly to respond to any potential pollution event.

You'll be amazed at the variety of life we find in our rivers! Key groups we are looking at are;

  • Cased caddis
  • Caseless caddis
  • Mayfly Ephemeridae
  • Flat bodied Heptageniidae
  • Blue-winged olives Ephemerellidae
  • Olives
  • Stoneflies
  • Gammarus (fresh water shrimps)

  • Photos below; a kick sample in action and a mayfly.

    As one of the initiatives of Discovering the Esk Riverfly Monitoring equipment including; sampling kits for each volunteer, microscope sets, identification guides, new workshops and refresher training have been funded thanks to the support from players of the People's Postcode Lottery.
