My freshwater habitat: Catherine Hughes, the Washpool, River Irfon, Mid-Wales

26th March 2024

Engagement Officer Catherine Hughes explains why the Washpool (PwllGolchi) in the River Irfon catchment is a special place for her and many of the people she works with.

My work in the beautiful River Irfon catchment in mid-Wales relies on having strong connections with local people. The Washpool is a very special spot along the river and it’s the place I’ve visited most since joining Freshwater Habitats Trust in 2021.

What do you love about the Washpool?

With its deep water and surrounding waterfalls, the Washpool (PwllGolchi in Welsh) feels like a magical place. The Washpool has a long association with the local farming community: it was historically used for sheep dipping and has the remnants of a sheepfold (a dry stone sheep pen) on the far bank. This historic feature has helped to shape the Irfon, creating different depths in the river.

The Washpool is part of the main river Irfon about a mile out of Llanwrtyd towards Abergwesyn. It has easy access, which means it works well for education events and I’ve spent many happy days with local school groups, from nearby Garth and Llanwrtyd, doing kick sampling and water testing.

Kick sampling is a simple technique for dislodging creatures on the riverbed, using nets and trays, so they can be identified. Using this method, local children have found several fish species, such as minnows and small trout, along with invertebrates, including mayflies and caddisflies.

These activities are great fun but they are also helping to connect people with the freshwater environment at an early age.

As Engagement Officer on the new River Irfon Catchment Project, my role is to be inclusive as possible to work with all parts of the local community. So, I am looking forward to discovering more of the species that live in the Washpool with people of all ages over the coming months.

Why is it important that we learn more about the River Irfon catchment?

The River Irfon stretches from Abergwesyn to Builth Wells and its catchment is a Special Area of Conservation because of its freshwater biodiversity. It’s one of Britain’s best remaining freshwater landscapes and includes one of the last UK populations of a species called Freshwater Pearl Mussel. However, water quality is declining and there are now calls to improve the catchment.

To improve water quality and reverse the decline in freshwater biodiversity, we need to assess water quality and monitor species, as well as putting in place practical improvement measures. Through our previous work in the catchment, and our new River Irfon Catchment Project, we are assessing all aspects of the Irfon’s freshwater environment, including the river’s tributaries and floodplains, as well as its associated ponds and wetlands.

A key part of the project involves working collaboratively with farmers – and this is my passion. We’ve been working with farmers to introduce measures to protect the freshwater environment.

Why is it so important for farmers to be involved with the River Irfon Catchment Project?

The River Irfon Catchment project focuses on getting farmers on board from the very start – and keeping them on board throughout. Farmers have been incredibly positive, including allowing us to run a citizen science project testing water for nitrates and phosphates across the 290 m2 of the catchment.

The farmers I worked with are rightly passionate about their catchment and are proud that the River Irfon still provides habitat for Freshwater Pearl Mussels. They are keen to address water quality issues and do what can be done to see these mussels thrive again.

I have been overwhelmed by the kindness of farmers and community groups in the catchment who have helped me to get connected to all interested parties. A special thanks has to go to Ken Chamberlain who runs a dynamic walking group and, with his fellow walkers, has totally embraced the water testing in some of the harder-to-reach parts of the catchment.

What is your connection to the River Irfon catchment?

I live in Hay-on-Wye, which is about 30 miles from Llanwrtyd Wells. The town of Llanwrtyd Wells is in the heart of the Irfon catchment and hosts a whole range of events from bog snorkelling and ultra marathons to a summer cider festival and real ale wobble race. It also hosts the Man V Horse event, for which I rode on my horse Bess back in 2009.

I’m 100% NorthWalian as my parents moved from the Lleyn Peninsula in their 20s to tenant a dairy farm in Worcestershire for one of the Cadbuy families. I loved the farm and particularly the cows. After studying agriculture at Abersytwyth, I worked for the Milk Marketing Board (MMB) which was a cooperative that bought milk from all UK dairy farms where milk prices was pooled, regardless of how many cows were milked or where the farms were located.

Once the MMB disbanded in 1993, the ethos of cooperative milk buying ended and small dairy farms quickly diminished, with numbers dropping from 32,000 to five.

I was awarded a Nuffield scholarship in 1992 to examine the dairy industry in New Zealand, Canada and the US and how they responded to freer markets. I then worked as an agricultural journalist for Farming News and Farmers Weekly before joining the communications departments of various agricultural and food companies.

Working on the River Irfon catchment project combines my connection with this beautiful Welsh landscape and my roots in the farming community.

When the Washpool becomes busy in the summer months, people push up the Irfon to the smaller ponds and rock features, like the Wolf’s leap and the Pwll Bo. The diversity of the washpool, with its different depths created by its sheepfold past, reminds us how livestock have played an important role in creating dynamic ecosystems.

Fy Nghynefin Dwr Croyw: Catherine Hughes, Y Pwllgolchi, Afon Irfon, Canolbarth Cymru

Mae’r Swyddog Ymgysylltu Cartherine Hughes yn esbonio pam for Y Pwllgolchi yn nalgylch Afon Irfon yn le arbennig iddi hi a llawer o’i chydweithwyr.

Mae fy ngwaith yn nalgylch prydferth yr Afon Irfon yng nghanolbarth Cymru yn dibynnu ar gael cysylltiadau cryf gyda pobl leol. Mae’r Pwllgolchi yn le arbenning ar hyd yr afon a dyma’r fan ble dw i wedi ymweld a fwyaf ers ymuno a Ymddiriedolaeth Cynefinoedd Dwr Croyw yn 2021.

Pam wyt ti mor hoff o'r Pwllgolchi?

Gyda’i dyfroedd dwfn a’i rhaeadrau cyfagos mae’r Pwllgolchi’n teimlo fel lle hudol. Fe’i defnyddiwyd yn hanesyddol ar gyfer dipio defaid gyda gweddillion gorlan ddefaid ar y lan bellaf lle mae’r garreg galed wedi cilio gan wneud y dyfnderoedd gwahanol yn fwy diddorol.

Mae mynediad hawdd i’r Pwllgolchi, sy’n golygu ei fod yn gweithio’n dda ar gyfer digwyddiadau addysg a dw i wedi treulio llawer o ddyddiau hapus gyda grwpiau ysgolion lleol fel Garth a Llanwrtyd gerllaw, yn gwneud samplu cicio a phrofi dwr.

Techneg syml ydy samplu cicio i ymwaredu creaduriaid oddi ar gwely’r afon drwy ddefnyddio rhwydi ac hambyrddau  fel y gellir eu hadnabod.Trwy ddefnyddio’r dull hwn, mae plant lleol wedi darganfod llawer o rywogaethu o bysgod fel minau a brithyll bach yn ogystal a infertebratau yn cynnwys Cler Mai a Phryfed Cadis. Mae’r gweithgareddau hyn yn hwyl mawr ond mae nhw hefyd yn helpu bobl i gysylltu gyda’r amgylchedd dwr croyw yn ifanc iawn.

Fel y Swyddog Ymgysylltu ar brosiect newydd Talgylch Afon Irfon, fy rol i ydy bod mor gynhwysol a phosibl i weithio gyda phob rhan o’r gymuned leol. Felly dw i’n edrych ymlaen i ddarganfod mwy o rywogaethau sy’n byw yn y Pwllgolchi gyda phobl o bob oedran yn y misoedd i ddod.

Mae’r Pwllgolchi’n ran o’r brif Afon Irfon sydd tua milltir tu allan i Lanwrtyd tuaf at Abergwesyn.

Pam bod hi'n bwysig i ni ddysgu am dalgylch Afon Irfon?

Mae’r Adon Irfon yn rhedeg o Abergwesyn i Lanfair-ym-Muallt ac mae ei thalgylch yn Ardal Cadwraeth Arbennig oherwydd ei bioamrywiaeth dwr croyw.  Mae’n un or tirweddau dwr droyw gorau sydd ar ol ym Mhrydain ac mae’n cynnwys un o boblogaethau olaf o rywogaeth o’r enw y Fisglen Berlog Dwr Croyw. Ond, mae ansawdd dwr yn gostwng ac mae galw am wella’r dalcylch.

I wella ansawdd y dwr a gwrthdroi’r bioamrywiaeth dwr croyw, mae’n rhaid i ni asesu ansawdd y dwr a monitro rhywogaethau, yn ogystal a rhoi mesurau gwella ymarferol mewn lle. Trwy ein gwaith blaenorol yn y dalgylch, ac ein pPosiect newydd Talgylch Afon Irfon, rydym yn asesu pob agwedd o amgylchedd dwr croyw Afon Irfon, yn cynnwys ei llednentydd, gorlifdiroedd, pyllau ac ei gwlyptiroedd.

Bydd gweithio ar y cyd gyda ffermwyr yn ran allweddol o’r prosiect – a dyma ble mae fy angerdd i. Rydyn ni wedi bod yn gweithio gyda nhw i gyflwuno mesuriadau i amddiffyn yr amgylchedd dwr croyw.

Pam bod hi mor bwysig cynnwys ffermwyr ym mhrosiect Talgylch Afon Irfon?

Mae Prosiect Talgylch Afon Irfon yn canolbwyntio ar gael ffermwyr i gymryd rhan o’r cychwyn ac i aros drwy gydol y prosiect. Mae’r ffermwyr wedi bod yn bositif iawn, yn gadael i ni redeg prosiect gwyddoniaeth dinasyddion yn profi dwr am nitradau a ffosffadau dros 290 milltir sgwar o’r dalgylch.

Mae’r ffermwyr dw i wedi gweithio gyda yn teimlo’n angerddol am eu talgylch ac yn falch bod Afon Irfon yn gartref i’r Fisglen Berlog Dwr Croyw hyd heddiw. Maent yn awyddus i fynd ar afael ar faterion ansawdd y dwr ac i wneud beth y gallent i alluogi’r Fisglen Berlog i ffynnu eto.

Dw i wedi fy syfrdanu gan garedigrwydd y ffermwyr a’r grwpiau cymdeithasol yn y dalgylch, sydd wedi fy helpu i gysylltu a phawb sydd a diddordeb yn y prosiect.Diolch yn arbenning i Ken Chamberlain sy’n rhedeg grwp cerdded deinamig a sydd, gyda ei gydgerddwyr, wedi croesawu’r profi dwr yn rhai o’r llefydd fwyaf anghysbell y dalgylch.

Beth ydy eich cysylltiad chi i dalgylch Afon Irfon?

Dw i’n byw yn Y Gelli Gandryll sydd tua 30 milltir o Lanwrtyd sydd yng nghalon talgylch Afon Irfon ac sy’n cynnal sawl digwyddiad fel snorcelu cors a marathonau mawr yn ogystal a gwyl seidr yn yr haf a ras siglo cwrw go iawn. Mae hefyd yn gartref i Dyn y.e Ceffyl ble marchogais fy ngheffyl Bess yn 2009.

Dw i’n 100% o dras gogledd Cymru. Symudodd fy rhieni o Ben Llyn yn eu ugeiniau i fod yn ffermwyr llaeth yn Sir Caerwrangon i un o deuluoedd Cadbury. Ro’n i’n caru’r fferm, yn enwedig y gwartheg. Ar ol astudtio amaethyddiaeth yn Aberystwyth, gweithiais i’r Bwrdd Marchnata Llaeth a oedd yn gydweithrediad oedd yn prynu llaeth o bob fferm laeth Prydeinig lle cyfunwyd prisiau, waeth faint o wartheg a odrwyd na ble oedd y fferm. Chwalwyd y bwrdd ym 1993, a dyna fu ddiwedd ethos o brynu llaeth drwy gydweithrediad a gwelwyd ddiwedd i lawer o ffermydd laeth bach yn sydyn iawn. Bu gostyngiad o 32,000 i 5. Roedd hyn yn ddiwrnod trist iawn, a dyma oedd diwedd ffermio cymysg a dechrau colled enfawr o fioamrywiaeth ar hyd ein tirweddau.

Dyfarnwyd Ysgoloriaeth Nuffield i mi yn 1992 i archwilio’r diwylliant llaeth yn Seland Newydd, Canada a’r U.D i weld sut yr oedden nhw’n delio gyda’s farchnad rydd. Yna, gweithiais fel newyddiadurwr amaethyddol i Farming News a Farmer’s Weekly cyn ymuno ac adrannau cyfarthrebu nifer o gwmniau amaethyddol a bwyd.

Mae gweithio ar brosiect talgylch Afon Irfon yn cyfuno fy ngysylltiad a thirwedd hyrfyd Cymru a fy ngwreiddiau yn y gymdeithas ffermio.

Mae amrywiaethau’r Pwllgolchi, gyda’i dyfnderoedd gwahanol a grewyd gan y gorlan hanesyddol yn dangos y pwysigrwydd a chwareodd anifeiliaid i greu ecosystemau deinamig, ac maent dal yn chwarae rhan hanfodol i wneud afonydd yn fwy diddorol.

Pan mae’r Pwllgolchi’n brysur yn misoedd yr haf, mae pobl yn gwthio i fyny’r Irfon i’r pyllau bach creigiau i Gamddwr Bleiddiaid a Pwllbo, sy’n elwa popeth i lawr y dalgylch. Mae amrywaieth Y Pwllgolchi, gyda’i ddyfnderoedd gwahanol sydd wedi eu creu gan gorlan yn y gorffennol yn ein hatgoffa sut mae da byw wedi chwarae rhan bwysig wrth greu ecosystemau deinamig.
