An Action Plan for Wilson Inlet and it's catchment is
being developed based on the views and wishes of the
community and the available information on the
environmental condition of the catchment and the Inlet.
In addition to nutrient reduction activities in the
catchment the action plan for the Inlet recommends:
- Continuation of western openings within 100 m of the
western cliffs to stabilise and deepen opening channels
with a consistent opening.
- Evaluation of opening the bar at a higher level to
obtain maximum sand movement and scouring.
- Dredging in Wilson Inlet to increase marine exchange
to be limited to works on the existing channel so that
changes in water quality can be assessed whilst
managing the risks of stratification.
- Manage Inlet floodplain to improve nutrient reduction
- Investigate potential local causes of algal growth at
Poddy Shot point and evaluate algal removal strategies
- Although the Inlet is under stress from catchment
derived nutrients, the water quality is in sufficiently
good condition that large scale intervention in the
form of a permanent opening (with its attendant
impacts) is not recommended. The rate of decline is
sufficiently slow that there is time for nutrient
reduction activities in the urban and rural catchment to
improve water quality in the short to medium term.
