The problem arises when this stratification is broken down quickly, causing the two layers to mix or ‘turnover,’ according to Texas AgriLife Extension. And that means we’re now entering the season of lake stratification – but that’s a lesson for another day. Turnover is a natural and common occurrence, and it can certainly take a toll on aquatic life. Here in Madison, Spring mixing is well underway, if not already completed. Thousands of dead fish, ranging from huge grass carp to tiny threadfin shad, have washed onto the rip. You can see this phenomenon in action in the first half (non-stratified) demonstration of the video below: LES WINKELER THE SOUTHERN Wed 0 MERMET - Its not a pretty picture. According our friends at the International Institute for Sustainable Development, who oversee Canada’s Experimental Lakes Area, this Spring mixing “is extremely important in freshwater lakes, as it is the event that is responsible for replenishing dissolved oxygen levels in the deepest lake waters.” There is a great deal of information about lake turnovers world-wide. turnover and having the same person doing all the visits A reliable pet. That means a persistent wind can mix oxygen into the entire lake – all the way down to the bottom. The colouration of the water is seen in daylight and in shadow. We have over 200 professional, trained, insured and bonded pet sitters and dog. And, even better for the lake, that water is reaching a point where the temperature (and, therefore density) is the exact same throughout the entire lake. But, right about this time each spring, an event crucial to the life in a lake is taking place.
