Wharfe Riverfly Monitoring.
Stephen Cheetham, Riverfly Monitor on the River Wharfe, Yorkshire, UK.
Part of the Riverfly Partnership’s Anglers Riverfly Monitoring Initiative (ARMI) to monitor water quality and safeguard our rivers and streams.
Whatever the weather, I can be seen, up to my waist in the River Wharfe every month at Addingham High Mill –brandishing a large net. But before anyone reports me to the river bailiff, I would like to point out that I am not using it to try to catch any fish!

Instead I am one of an army of over 400 volunteers who regularly look after our rivers and streams in the UK, checking on the levels of invertebrate life to help to monitor water quality. The nets used are specifically designed to collect a sample from the gravel on the riverbed so that they can be checked for a range of insect life.
The initiative is the responsibility of the Riverfly Partnership, a national group that organises and trains teams of volunteer samplers who look for the bugs and mini-beasts living in the riverbed and report back on the numbers they find. Most of the tiny creatures we are looking for are the water-living stage of winged insects such as mayflies and sedges. They are sensitive to changes in water quality and if they are not present in sufficient numbers, I and my fellow samplers alert the Environment Agency. Their job is to investigate and take action if they find that an incident of pollution has caused the drop in numbers.
Last year Addingham Beavers joined me for a sampling session and were fascinated by what they found. The group of over 20 children and their leaders, along with parents and volunteers, spent a happy if frenetic hour identifying the bugs in their sample trays before returning them to the river (leaving me and my fellow samplers helping me out exhausted!)
Anglers and environmentalists know about the bugs that live in the river but most people are unaware of them. Anglers are often the first to be aware of changes in water quality because they know their rivers so well. And they’re in a good position to act as samplers as they don’t need much persuading to get into the water!
Most of the nationwide teams of samplers are made up of anglers, a fact which surprises many who think that fishermen are only interested in catching fish and eating them. But fishing is now mainly about conservation and most fish caught are returned to the river unharmed.
Currently, on the River Wharfe, we have just a small team of samplers but much more needs to be done to ensure better coverage. We would like to train more sampling teams to sample other stretches of the Wharfe and also other local rivers, but we need funding to do this. Thankfully, with funding from the Salmon & Trout Association, West Yorkshire Branch, and the Aire Rivers Trust, we are now able to begin training 12 new volunteers to sample 12 points on the River Aire, starting March 2015.
Anyone interested in volunteering as a sampler, or in sponsoring the training of sampling teams or advising on funding for these can contact me on firstname.lastname@example.org.
