For lakes, modelled predictions are made at the scale of the overall lake.
Uncertainty is a component of any freshwater monitoring or modelling. For example, river flows and levels
fluctuate throughout the day, and nutrient levels will vary depending on how much rainfall and runoff is
occurring. Pathogens and algae will grow in response to a range of factors, such as temperature, light and
river flow. This uncertainty is described in terms of ‘confidence’.

The site was
found to be generally well maintained and tidy during inspections, and all consent conditions were being
complied with. No objectionable dust or odour effects were observed, bunding was well maintained and site
contouring was adequately directing all quarry runoff to the stormwater settlement ponds. Discharges after
heavy rainfall were clear.

It was found that all materials at the site were permitted by the conditions of the consent. It mostly
consisted of broken concrete. There had been recent heavy rainfall resulting in only a few small puddles,
with no run off observed. There were no matters of concern to note during the inspection. In the
composting area it was found that the site remained well bunded with only some puddles present …
