Summary

Objective
Control of pest species to improve water quality and reduce spread of pest species.

Works 
Small outbreaks of salvinia have occurred periodically since the 1990s and is sprayed as required. The most recent outbreak was in 2013. Of most concern for residents is the occasional outbreaks of red azolla, algae blooms and Mexican yellow water lily (sprayed when it reaches over 50% coverage near outflows).

Outcomes
Spraying (ongoing since early 2000s).

Benefits

This project will improve water quality and reduce the spread of pest species at Ann St Lagoons.

Lesson

The increase in floating water plants (red azolla, duck weed etc.) is most likely due to nutrient load from roosting birds on islands and current cyclic climatic conditions. It is sometimes difficult to convince residents that it occurs in cycles.
