Assessing risk of oligomictic conditions in sub-tropical water supply lakes (2016-2023)
Abstract
This proposal seeks to use a combination of environmental monitoring and numerical modelling techniques to assess the risk of oligomictic/meromictic conditions in sub-tropical drinking water supply reservoirs. Emerging evidence suggests sub-tropical drinking water supply reservoirs could transition to an oligomictic/meromictic state with increasing age and projected changes in global climate. While this risk is poorly understood it has potentially significant implications for the long-term reliability of water supply and potable water treatment costs. By addressing this knowledge gap it is anticipated that this project will allow effective management responses to be developed to ensure the long term sustainable use of these water resources.
