Pant-y Llyn is Wales’ and Britain’s only recorded Turlough. It is a key feature of Cernydd
Carmel SSSI and SAC and a groundwater dependent terrestrial ecosystem (GWDTE) that has
been identified as being at risk of significant damage from enriched groundwater input.
This investigation is a collaborative project between hydrogeologists from Environme...

Context 1
... the longest lag followed the peak rainfall event on 30/9/2010, there was substantial additional rainfall following this date which would influence the peak water level timing within the turlough. To further examine the relationship between rainfall and peak water levels, cumulative rainfall plots were generated and compared to the corresponding turlough water levels for this and a second major filling event in January ( Figure 7 (a) and (b)). During the first filling cycle the water in the turlough continues to rise for a significant amount of time after rainfall has ceased ( Figure 7 (a)), peaking 8 days after the last major rainfall event. ...

In contrast, at higher stages the water level in the turlough begins to fall almost immediately after rainfall ceases ( Figure 7 (b)). ...
