When this pool was excavated of accumulated sand (in 1997) there was no sign of Aponogetum distachyus, however the tubers that grow in the bottom mud can lie dormant in unfavourable conditions, such as drought. Within a year the newly cleared water surface was covered by the oval shaped leaves of the pondweed. Seed germinates freely on the water surface.
