If other conditions also favour eutrophication, sensitive ecosystems may experience additional algal and plant growth, loss of sensitive macroinvertebrate taxa, and higher respiration and decay rates. The same operating conditions apply, so if the river is not able to be used, water is transferred to Coffs Habour from Shannon Creek Dam. All samples were collected using approved field protocols and have been analysed in accredited laboratories. This section gives the Water Quality Objectives (WQOs) and the River Flow Objectives (RFOs) for the Clyde River and Jervis Bay catchments which should be used to develop plans and actions affecting water quality and river health.

This dashboard shows information on the data collected by the regional councils for water quality indicators, analysed as state and trend. National bottom line: Annual median 0.24 mg NH. In combination with other conditions favouring eutrophication, DRP enrichment drives excessive primary production and significant changes in macroinvertebrate and fish communities, as taxa sensitive to hypoxia are lost. If the Nymboida River cannot be used as source water due to low flow, less than 225 Megalitres (ML)  a day or the turbidity is too high, such as after a wet weather event or flood, our water is sourced from the off stream storage of Shannon Creek Dam. It offers spectacular scenery, an abundance of wildlife and some exhilarating whitewater adventure! The Nymboida River also gravity feeds water to Shanon Creek Dam when required. Around 35,000 ha of good agricultural land are used for sugar cane production by 600 growers in Australias most southerly cane growing region, located at downstream ends of the Tweed, Brunswick, Richmond and Clarence River Catchments. Ecological communities are impacted by moderate DRP elevation above natural reference conditions. Residents are reminded that Level 1 Water Restrictions apply to all properties on town water supply in the Clarence Valley. Queensland Water Commission. increased the potential for water quality problems to occur, especially given the chronically poor water quality within the river caused by wastewater discharges, brackish seepage from irrigation leach drains, and irrigation return flows. The predicted average infection risk is 2%*. 20-30% of the time, the estimated risk is >=50 in 1000 (>5% risk). The quality of Council's drinking water is regularly monitored and analysed against the values in the Australian Drinking Water Guidelines. For this reason the water is re-chlorinated at the 21ML reservoir to ensure a lasting residual, which protects the water from any sources of recontamination in the distribution system (further information on the addition of chlorine to water supplies is available below). Depending on the sampling history duration, five, ten and fifteen year timescales are available: The Cawthron Institute has worked alongside regional councils to verify the processes and methods used for data collection, laboratory analysis of samples collected and the statistical analysis and interpretation of the results presented. The quality of Council's drinking water is monitored regularly (more than 20 drinking water samples each week) and analysed independently at a NSW Health laboratory against the values in the Australian Drinking Water Guidelines. Figure 29. Appendix 3. Molesworth is open to tourists during the summer months, with historic areas to visit and some camping available. Serious water quality problems are associated with the drainage of acid sulfate soils, which results in the flow of acidic (low pH) water into the surface water system. Factsheet.
