Results explained

In the northern section of Tuggerah Lake, reductions in average turbidity levels in 2014 were counteracted by increases in average algal concentration. A slight decrease in seagrass depth range was also observed as compared to 2013. The balancing out of these changes resulted in the overall grade for this zone remaining the same as last year.

Results explained

The northern part of Tuggerah Lake was stabilised in 2013 achieving a fair grade as in the previous year. Fair turbidity levels and moderate seagrass depth range both similar to 2012 results were however slightly offset by increases in chlorophyll concentration.

Results explained

Ecological health in the northern part of Tuggerah Lake was fair in 2012 having declined slightly from the previous year. Water clarity was fair with only moderate turbidity and seagrass depth range recorded. Algal levels were higher than in 2011 and can be attributed to high summer rainfall and nutrient loads from the catchment area.
