(5) Due to an error on the contractor’s behalf, approval was not sought to change the silt drying location. However, works were undertaken in accordance with the Environmental Management Plan (EMP) whenever possible, with occasional minor amendments as required to accommodate actual site conditions and to improve road safety.
(6) Works were undertaken in accordance with an Environmental Authorisation as well as an Environmental Management Plan.
(7) During removal of woody invasive weeds from Fadden Pond and to accommodate machinery access to the pond some of the casuarinas and yellow flag iris were removed. The island has since been replanted with nine (9) casuarinas. Currently, more aquatic plants such as yellow flag iris are being planted around the riparian zone of the pond.
(8) The algae is not blue-green algae.
(9) Algae occurs naturally in fresh and marine waters and algal blooms are often a normal part of the seasonal cycle. Algae performs a vital role in aquatic systems by removing excess nutrients, particularly nitrogen and phosphorous and they release large quantities of oxygen into the water column and provide a food source for aquatic insects, shrimps, tadpoles and birds. In lakes and artificial wetlands, it is natural for the phytoplankton population to rise and fall as a response to the amount of sunlight, temperature and nutrient levels in the water.
(10) Fadden Pond like all other lakes and artificial wetlands will experience rise and fall in algal population as a response to the amount of sunlight, temperature and nutrient levels in the water.
(11) Stormwater from Fadden Pond flows towards Isabella Pond and eventually into Lake Tuggeranong. There were no water outflows during the sediment removal process, hence the sediment was contained within the pond and turbidity testing was not a requirement.
(13) There are currently no plans to commission a study of the pond.
