The water level at La Vallette Ladies' Pool can drop by 30 cm, or nearly one foot, between tides.
For many years the pools at La Vallette were unloved and only used in the summer, or year round by a very few swimmers.
The Ladies' Pool once held swimming and diving competitions, but these gradually moved indoors to Beau Sejour.
A massive community effort ten years ago began restoring the pools and surrounding area.
Now there is a new cafe, improved railings and walkways and a seasonal sauna.
When Covid-19 hit in 2020 the appetite for year round swimming began, and the pools' popularity has grown and grown.
The diving board remains, despite issues over safety guidelines on the water depth below it, exactly one year ago.
Now, the States want a local firm to look at stemming some of the leaks at the Ladies' Pool.
Measurements between tides show the level can drop by 30cm or nearly one foot.
Initial assessments show leaks at the mortar joints and the between the bedrock and walls.
Jim Robinson from Natural Environment says it is impossible to make a tidal outdoor pool, exposed to easterly and southerly gales, completely water tight:
“While it may not be realistic to expect to entirely seal this kind of historic structure, these works will help us understand the art of the possible so that we can make improvements and enhance this much-loved community asset.”
