At least two lowerholes must be provided so that in the earlystages the water level can be kept low, andyet the pond can be flushed. A large drain,to be closed during the summer, is placed atthe bottom of the Victoria pond. Thisenables one to clean the pond thoroughlyafter the removal of the water plants.
