Cell Descriptions - South East Natural Resources Management Board

SE8 – Rivoli Bay
and Silky Tea-tree shrubland (Bachmann, 2002). The hydrology of the area that contains Mullins
Swamp has been highly modified through drainage works. A stop bank was created along the
northern section of the swamp and this halted northerly flows, forming the sill of what now is
Mullins Swamp, and redirecting flows southward toward Lake Frome via the Lake Frome North
Drain. The Reedy Creek-Mount Hope Drain discharges into Mullins Swamp through the Mount
Hope Cutting and is the primary source of water for the site. Mullins swamp and the inflow and
outflow drain fall under the jurisdiction of the SEWCDB, however the swamp is leased and
managed as a wildlife sanctuary. Hydrological management of the site is considered adequate for
maintaining the biodiversity for which the site is recognised. However, water level changes over
the past decade should be collated and investigated for trends of decline in association with
declining groundwater in the region.
Opportunity to monitor water quality and volumes entering Rivoli Bay via the Lake Frome drain
and utilise wetland polishing to improve water quality if required.
Conservation Analysis (GIS)
Total conservation values sum to 95.21, a low total within the region. The map of detailed
summarized conservation values shows low values throughout the dune ridges, except within
200m of the shore where medium totals accrue. The main values within the cell are for numbers
of threatened plant species, endemic plant communities within SA and extent of potential habitat
for Orange Bellied Parrot.
