An incredible sight on our Welsh rivers! 🐟🌊

Whilst surveying our rivers, our River Restoration Officers were lucky enough to spot sewin (sea trout) making their way upstream, leaping out of the water to navigate natural waterfalls and river obstacles.

Sewin are migratory fish that spend much of their adult lives at sea before returning to the rivers where they were born to spawn. They travel upstream, often tackling challenging stretches of river, to reach suitable gravel beds where they can lay their eggs.

These journeys highlight just how important it is to keep our rivers connected and ensure fish can access the habitats they need to complete their life cycles.

Always a special sight to see! 💚

Golygfa anhygoel ar ein afonydd yng Nghymru! 🐟🌊

Wrth arolygu ein hafonydd, cafodd ein Swyddogion Adfer Afonydd y fraint o weld sewin (brithyll y môr) yn symud i fyny’r afon, gan neidio allan o’r dŵr i oresgyn rhaeadrau naturiol a rhwystrau eraill yn yr afon.

Mae sewin yn bysgod mudol sy’n treulio rhan helaeth o’u bywydau fel oedolion yn y môr, cyn dychwelyd i’r afonydd lle cawsant eu geni er mwyn silio. Maent yn teithio i fyny’r afon – gan wynebu rhannau heriol yn aml – er mwyn cyrraedd gwelyau graean addas lle gallant ddodi eu wyau.

Mae’r teithiau hyn yn amlygu pa mor bwysig yw cadw ein hafonydd yn gysylltiedig, a sicrhau bod pysgod yn gallu cyrraedd y cynefinoedd sydd eu hangen arnynt i gwblhau eu cylchoedd bywyd.

Mae bob amser yn olygfa arbennig! 💚

Nant Clais Brook Restoration

This week has seen West Wales Rivers Trust and AVACC members on site to oversee the introduction of gravels to improve spawning habitat in the brook.

This, together with numerous woody structures introduced a few weeks ago, will hopefully tempt salmon and sea trout back into the brook to reclaim historic spawning grounds, which were damaged by construction of a housing estate which resulted in the re-routing and dredging of the brook.

The majority of the restorative work is now complete, with potential for some additional work further upstream next year.

Building natural solutions, one stream at a time 🌿💧

Recently, a brilliant team of volunteers from Princes Gate joined us for a hands-on day creating leaky dams — a simple but powerful natural flood management technique.

Using wood sourced on-site, the team learned new skills and helped build three structures designed to slow the flow of water during high rainfall — just like fallen trees would naturally do in a healthy river system.

So, what’s the impact?

🌊 Reduced flood risk downstream
🌱 More water held in the landscape
🐟 Healthy rivers that still allow fish and wildlife to move freely

A huge thank you to the team for getting stuck in and making a real difference! 💚

Adeiladu atebion naturiol, un afon ar y tro 🌿💧

Yn ddiweddar yn Fferm New Holums, tîm gwych o wirfoddolwyr o blant y ffatri Princes Gate yn Nestlé ymunodd â ni am ddiwrnod ymarferol yn creu rhwystrau gollwng dŵr — techneg rheoli llifogydd naturiol syml ond pwerus.

Gan ddefnyddio coed a gafwyd ar y safle, dysgodd y tîm sgiliau newydd a chafodd help i adeiladu tri strwythur wedi’u cynllunio i arafu llif dŵr yn ystod glaw trwm — yn union fel y byddai coed cwymp naturiol yn gwneud mewn system afon iach.

Felly, beth yw’r effaith?

🌊 Lleihau risg llifogydd i lawr yr afon
🌱 Cadw mwy o ddŵr yn y tirwedd
🐟 Afonau iach sy’n dal i ganiatáu i bysgod a bywyd gwyllt symud yn rhydd

Diolch mawr i’r tîm am ymroi a gwneud gwahaniaeth go iawn! 💚

Yn ystyried cael eich tîm chi wedi’i gynnwys?

Have you seen a yellow fish? 🐟💛

Last month, we had a fantastic evening at Nant y Fendrod with the 32nd Swansea Cubs, getting hands-on with the campaign — raising awareness about how everyday pollution can end up in our rivers.

Did you know? Road drains flow straight into local watercourses, meaning anything poured down them — from oil to detergents — can harm wildlife.

Together, we:
🎨 Stencilled by storm drains
🧠 Learned how drains connect to rivers
📢 Put up awareness posters
🗑️ Collected 4 bags of litter before it reached the water

A brilliant effort from everyone involved! 💛

Huge thanks to Natural Resources Wales for supporting these events along Nant y Fendrod this year.

Ydych chi wedi gweld pysgodyn melyn? 🐟💛

Mis diwethaf, cawsom noson wych yn Nant y Fendrod gyda 32ain Clwb y Llewod Abertawe, gan ymgolli'n llwyr gyda'r ymgyrch — codi ymwybyddiaeth am sut gall llygredd bob dydd gyrraedd ein dyfroedd.

Oeddech chi'n gwybod? Mae draeniau ffyrdd yn llifo'n uniongyrchol i'n cyrsiau dŵr lleol, sy'n golygu y gall unrhyw beth a lifir i mewn iddynt — o olew i sebon — niweidio bywyd gwyllt.

Gyda'n gilydd, fe wnaethom:
🎨 Stensilio ger draeniau storm
🧠 Dysgu sut mae draeniau'n cysylltu â'r afonydd
📢 Gosod posteri i godi ymwybyddiaeth
🗑️ Casglu 4 sach o sbwriel cyn iddo gyrraedd y dŵr

Ymdrech wych gan bawb a gymerodd ran! 💛

Diolch mawr i Adnoddau Naturiol Cymru am gefnogi'r digwyddiadau hyn ger Nant y Fendrod eleni.
