This story map shows the River Corran with water collection results (Red marker), any blockages spotted (Blue marker).

The Laugharne Citizen Science team completed its June survey of the River Corran and Mackerel Lake stream on 11 June 2026, testing all nine monitoring sites across both watercourses. The results contain two significant findings: a sharp pH crash across the upper and mid Corran that mirrors what we recorded on the River Taf two days earlier, and an exceptional phosphate spike on the Mackerel Lake stream that requires urgent investigation. The pH Crash — What the Numbers Show T

Interesting document- one objective is the removal of Himalayan Balsam - there is a lot emerging on the River Taf opposite Llanddowror- the worry must be when this self-seeds it could spread quite rapidly downstream and into the marshes. This is something we need to look at as a group and the wider community.

River Taf Monitoring Update — June 2026 The Laugharne Citizen Science completed its latest monthly water quality survey across the River Taf catchment on 9 June 2026, testing at four sites from Login in the upper catchment down to Llandowror. The results present an interesting and scientifically significant picture — one that illustrates both the resilience of the river and the value of continuous, multi-point monitoring. The headline finding: a sharp drop in pH The most stri

You may have noticed members of the Laugharne Citizen Science Group (LCSG) out on the streets recently, weeding our pavements and kerbs by hand. A few residents have asked why we are doing this ourselves, especially since we all pay council rates for local maintenance. It is a completely fair question, and as a group, we want to share exactly why we have taken on this project. Our main goal as LCSG is to protect Laugharne from the chemical spraying of Nomix Dual, a powerful i

We have tested for a few months now, but still need to build up the dataset before conclusions can be drawn. Some months only have partial data either because we did not run the test or test was not conducted waterside. The water temperature is rising as one would expect. Ammonia came down from last month, but Nitrate is up as is phosphate at one location. Early days but we are building up data. The reason for just 2 sites is due to the length of time the test back at base ta

A team of 10 people- members of LCSG and some non-members spend 2 hours today weeding and removing soil and leaves from Cliff rd. From the state of the road edge it has been left for many years but a good start was made. If you want to help with weeding please do contact us, it will be an ongoing project to make sure Carmarthenshire County council are happy with what we are doing and continue not to spray Nomix Dual which contains glyphosate. Thanks to Draper tools who gave u

No great changes in the results for May, although OH levels at Abercorran were above 9.0 . The Corran and Mackerel Lake stream were both had low water running. No fish were seen and there was little aquatic life visible- water temperatures are still lowish. A skylark was heard and seen on the road towards Glancorran.

Laugharne Citizen Science tested the river on the 13th May 2026. The river level was lower than last month, there has been less rainfall in the last month. The only observations was a Kingfisher was seen at the Whitland testing spot and a trout was seen rising to flies below the road bridge in Whitland. PH levels are still elevated and have been reported to NRW and West Wales River Trust. Phosphate levels were higher at one testing location- probably as potatoes had been sown

Based on the data for the River Taf in April 2026, the situation is significantly more extreme than in the smaller tributaries. While the Nitrate levels are lower, the pH levels have reached a critical and potentially dangerous stage. Here is the breakdown of the April 26 results for the three main Taf sites (Llandowror, Whitland Church, and the Water Monitoring Station): 1. Critical pH Readings (The Primary Concern) This is the most alarming part of the Taf data. The pH has

Spring River Health Report (April 2026): Tracking the "Invisible" Surge In April 2026, the monthly monitoring has revealed a significant trend across the catchment. While our rivers appear visually clear and healthy, the chemical data reveals a hidden "nutrient surge" that is affecting the river’s ecology. The Post-January Loading Phase Under current Welsh regulations (CoAPR), the closed period for slurry spreading ended on January 15th. Since then, there have been three mont

Great work by Annie and Amanda today in Clifton st. Plenty more to do so if you want to help do contact us.

March results showed readings for Ammonia at all locations. Not critical but an indication that agricultural run off is occurring- not surprising given the rain we have had. Nitrate levels were up slightly on Feb 26 but down on Nov 25. There was a high reading for Phosphate at Llandowror, but again not critical. Most tests show raised levels apart from St Clears, although there was some eddying going on at that location. Dissolved Oxygen was good. PH is a slight concern two r

March saw a slight increase in Nitrate, PH and EC levels. This could be a result of the heavy rains we have had recently causing some agricultural run off. The PH levels are below danger level for aquatic life, but need to be monitored. Any further rise would need investigating, although they would have to remain elevated for many months to cause irreversible damage. Dissolved Oxygen levels are good- ideal for maintaining aquatic life in the river system. Ammonia was only pre

Attached is a document that was submitted to Laugharne Township Community Council(LTCC) in response to the proposal submitted to LTCC by Mr Kirkwood. LCSG is committed to working with all relevant parties to develop a long term plan to try and reduce the flood risk in the township.

Results of today's water collection and testing on the River Taf. Ammonia was up, phosphate slightly down and nitrate quite a bit down. The river was running pretty fast although using the water clarity meter it was clear.
