Taf Fechan Reservoir

Merthyr Tydfil

 
   

The Taf Fechan gathering ground, an area of 8,351 acres, extends from the highest point of the Breconshire Beacons (Pen-y-fan, 2,907 ft. above sea level) in a southerly direction to the reservoir embankment at Pontsticill.

 

The rainfall on the catchment area averages 72.86 inches at the Neuadd Reservoirs and about five miles south, 58.72 inches at Taf Fechan Reservoir. The rainfall drains off the mountainside to the valley and is impounded in three reservoirs.

 

The first reservoir constructed for the supply of Merthyr Tydfil, was Pentwyn Reservoir (known locally as Dolygaer Lake) under an act obtained by the Merthyr Local Board of Health. in 1858.

 

The Pentwyn Reservoir was combined into the Taf Fechan reservoir which was completed in 1927.
