The Finn Valley Leisure Centre pool has been unexpectedly closed for maintenance today, Wednesday.
Staff arrived this morning to discover the 25-metre pool completely drained of water.
Refilling the pool will take an estimated 2-4 days, and leisure centre goers are asked to bear with the team in their efforts to resume lessons.
The gym facilities are open as normal.
“Please don’t be calling the centre as all phones are busy calling intensive swim lesson parents,” a notice said.
“We will continue to keep you updated but it will be 2-4 days approx to re-fill the pool.”
