In recent years, the quality of lake water has been severely affected by high nitrogen levels due to agricultural run-off from surrounding farms, seepage from domestic septic tanks and inflows of nitrogen rich water from Lake Rotorua. Effects have included an almost permanent algal bloom in the Okere arm of the lake and choking lake weed growth in other still areas of the lake. Some hold fears that if the problem is not dealt with quickly, low levels of light (due to cloudy water) and oxygen deficiency in the lake may lead to it's eventual eutrophication (sometimes called biological death). A septic tank is part of a small scale sewage treatment system often referred to as a septic system, which consists of the tank itself and a leach (drain) field. ...
