I’ve been surveying our River Yeo near Spreyton for some time now and was interested to read a CSI report card I was sent a few months ago.

Thankfully, the river always scores well on pollution levels and low Phosphate but I was really disappointed to see its overall score marked down because of a lack of wildlife sightings.

This spurred me on and Simon (senior monitoring officer at Westcountry CSI) recommended the Field Studies Council Freshwater Name Trail to help me identify underwater critters rather than just relying on those I could see above water.

It’s been really interesting learning about this other world I knew very little about.

It’s absorbing, enjoyable and very satisfying when you spot something that’s a good indicator of clean water.  I’d never heard of Flattened Mayfly Nymphs before, let alone seen one.

I have nicknamed our group the ‘Sewage Sleuths’ because, in essence, that is what we are looking for.

When we started we didn’t know that. We all got involved because we love the Valley with the River Par running through it. We all walk its length regularly and still marvel at its granite grandeur, industrial past, and Mother Nature’s repossession; we can’t help but feel a custodial responsibility for its health and wellbeing.

We didn’t expect to find contamination. Through the WRT citizen scientist project, we have come together as a group out of common interest and have developed from otter spotting to water monitoring to water fly identification.

In our search for the source of sewage we have expanded our monitoring to the entire length of the Par well beyond the Valley, and we report our findings to the Environment Agency and South West Water.

We have had amazing support from Westcountry Rivers Trust and feel we are making real progress in identifying sources of contamination that will protect the future health of our river.

We may be in search of sewage, but the journey is still a pleasant one, in good company, finding flora and fauna on the way or discovering small items of industrial past previously overlooked.

Our last visit concluded with three of us staring into sun-dappled water watching water boatmen (after a full discussion as to their identity of course) ferrying themselves up and down, side to side, oblivious to our interest.

It was a wonderful reminder that many of life’s pleasures are simple and free, that many of them can be found in the Valley and the reason we volunteer our time to its protection.

Our group comprises members of the Friends of Luxulyan Valley. We began our roles at citizen scientists in 2020 following training from CSI coordinator, Lydia Deacon.

Since then we have been able to carry out river sampling at numerous spots from near the source to the lower river near Par Sands.

There are six of us: Dave Burrell, Mandy Case, Joan Farmer, Veronica Jones, Roger Smith and Dave Stillings.

It all began with the otter surveys which some of us have carried out in and around Luxulyan Valley for years. We knew otters used the river but that was about all we knew.

How clean was the water? Was the biodiversity of the river as it should be? Official statistics were pretty tough to understand and then we discovered the Westcountry Rivers Trust, an organisation that is now close to our hearts.

And better still, it had a citizen science scheme! So now we check our river every month and are building up quite a database.

I first developed my interest in Freshwater Biology in 2006 on a visit to Lundy with a biologist who fostered my interest and gave me a free masterclass.

I have surveyed Lundy’s ponds and streams ever since and continue to do so.

When I was close to retirement, I undertook a BTEC in biological recording at Cornwall College’s Camborne campus and continued to specialise in Freshwater biology.

When a friend told me of a free course at Hatherleigh in 2014 to survey for the Riverfly Project, I jumped at the opportunity.

Together with my friend Barry, I surveyed the River Torridge near Bradford Mill until September 2016. Following a conversation with another friend, Iain, we determined to establish Riverfly in Cornwall.  At that time there was no Riverfly presence in the county.  Since January 2017, we have trained over 90 surveyors and established over 80 survey sites in half a dozen catchments.

In June 2017, Simon Browning (senior monitoring officer at Westcountry Rivers Trust) suggested that I might like to combine my surveys with the Westcountry CSI abiotic surveys.  I did so and survey my own three sites in North Cornwall for invertebrates and the basic abiotics. I have since completed 128 surveys.

The latest expansion of my surveys is to establish Riverfly and CSI on the iconic Cornish River Tamar.  I intend adding a site to my own three and encouraging further survey sites to be established further downstream.

With the cutbacks to all public sector environmental bodies, these two citizen science projects are essential to maintain any sort of monitoring of freshwater bodies.

Any breaches are quickly identified and reported.  My interest in freshwater invertebrates is enhanced by knowing that these surveys are filling the gaps left by statutory bodies and ensuring a watch is kept on these scarce and vital resources.

We want everyone who loves being by the river to enjoy their time their safely while also respecting the environment around them.

Our Westcountry CSI volunteers receive full training relating to how to safely collect river health data and about their freshwater environments.

Do make sure you read the Water Safety Code and safety tips for anglers too.

And if you love to take your dog with you on your river wanders, there are a few importnat things to consider. You can read about them at Dogs & Our Rivers 

For the wild swimmers among you, please read our statement and info on the Our Reports page.

You can read our positive impact for rivers in the Westcountry in our Annual Reviews and as part of our national network at The Rivers Trust.

Please check if you can legally access the site and take all your rubbish away with you to dispose of correctly.
