Lake Illawarra Authority - Lake Facts: Water Quality (Site not responding. Last check: 2007-10-08) |
 | | Although the lake is shallow, wind induced circulation patterns result in the water being well mixed in the main body of the lake. |
 | | Sediments which flow into the lake carry with them nutrients, particularly phosphorous and nitrogen, which are present in animal faeces, detergents, fertilisers and sewerage, which are all part of urban and rural runoff. |
 | | Salinity in Lake Illawarra is generally lower than the ocean, reflecting physical factors such as the intermittently closed nature of the entrance, the volume of stormwater, rainfall and runoff occurring. |
