The pond proposed for Brewery field is large, about 15-19m across. It is designed to be able to withstand drought which is expected in this part of the country, especially recently.
So even when the central area of water recedes, the areas left behind are all over-layed with a geotextile that protect the pond liner from the sun, from dogs claws and other traffic and also means you don’t have to look at black plastic! The pond will be initially filled by bowser, then it will have to be topped up solely by the rain collected from the shelter.
Here is a visual of the pond brimming. I now regret this visual, after watching my own pond in the dry, holding back from using the tap. Once filled, it may never get back to this state of full to the brim again. But what we need to remember, is the habitat left as the pond subsides, is still interesting, still attractive, still perfectly natural and normal for a pond – they are fluctuating things, plants and animals come and go. This is also the joy of a pond. The time lapse photography and regular surveys we intend to set up will document this, and become valid scientific data.
