Water bodies such as lakes, ponds or water supply reservoir show vertical stratification of their masses, at least for some extended time periods. Density differences facilitate the process of stratification. Temperature and dissolved substances contribute to density differences in water. As a result, thermal stratification can be established during the warm season if the water bodies are sufficiently deep. On the contrary, during the cold season surface cooling force the vertical circulation of water as a result turnover will occur. In warmer weather regions such as Bangladesh, India etc. this annual cycle spending more time in late summer and early fall. Thermal stratification is a common phenomenon here. Failure to identify and control, stratification, can cause low oxygen level, fish die-offs, excessive growth of plankton, failure of meeting regulatory standards, customers’ expectations. So, identify the early onset of stratification and developed operational response procedures that introduce appropriate control measures such as aeration to avoid potential impacts and minimize any adverse effects.
