During summer, the surface waters of lakes warm and become less dense than the colder bottom waters. This process is known as stratification and prevents surface and bottom water mixing. Stratification can occur intermittently in shallower lakes or for up to 9 months in deeper lakes (Figure 1). Under natural conditions stratification normally breaks down during the winter months when surface temperatures equilibrate with the bottom of the lake.
