Understanding Flooded Quarries


Flooded quarries are prone to wild claims, in particular about “hidden currents that drag you under” and the usual freezing water.


The water in quarries behaves in a similar way to lakes – it warms in summer and, if the water is deep enough, thermal layers might be present. Flooded quarries are spring or stream-fed, and of course water from underground is relatively cold in summer so you might find a patch of cooler water where the spring or stream enters. This will not kill you, but do be aware of it.

Ghostly Currents:

Quarries do not have hidden currents beyond the flow from filler streams and springs, and there are no currents that will drag a swimmer under the water.

Potential Hazards:

Potential hazards in quarries include industrial pollution (it’s worth investigating what was quarried there), and underwater hazards such as rocks, cars, old bikes, and usually a legendary body or two. So don’t jump or dive in unless you’ve thoroughly checked the area first, as you would for any swimming hole.

Steep and Slippery Sides:

As always, check there is a suitable and easily-accessible entry and exit point before you get in. Quarries by their nature have steep sides. They are often very deep, and it’s easy for weak or non-swimmers to stumble out of their depth.
