What is the advantage of turnover in temperate lakes?
Seasonal lake mixing Twice a year, unseen forces churn water from the depths of our deeper lakes and deliver oxygen and nutrients essential to aquatic life. This temperature-driven process of lake “turnover” allows aquatic life to inhabit the entirety of the lake as oxygen becomes more available.
Why is turnover important in lakes?
Lake turnover is extremely important in freshwater lakes as it is responsible for replenishing dissolved oxygen levels throughout the lake. When the lake is stratified in the summer months, the colder deep water (the Hypolimnion) is very low in oxygen.

What is lake seasonal turnover?

How does lake turnover affect fishing?
It makes the water off-colored and even muddy in some areas. The turnover can cause fish kills in some areas, but it is more common on smaller lakes with little moving water or in backwater creek areas where fish can't escape the water that is lacking oxygen.
What happens when the lake turns over?
As the surface water cools and gets heavier it wants to sink. Eventually this cooler water layer does sink and displaces warmer water in the lower portions of the lake and the entire lake “mixes” itself. Top goes to the bottom, bottom comes to the top, henceforth the name “turnover.”

How might Turnover in tropical lakes differ from turnover in lakes that exist in temperate regions think of the variation or lack of variation in seasonal temperature change?
How might turnover in tropical lakes differ from turnover in lakes that exist in temperate regions? Think of the variation, or lack of variation, in seasonal temperature change. Tropical lakes don't freeze, so they don't undergo spring turnover in the same way temperate lakes do.
What makes a lake turnover?
Lake turn over is a phenomenon that generally occurs twice a year, spring and fall. It is caused by water temperatures being different at the surface and in the lower regions of a lake. Lighter and heavier water switch places.
Where do the fish go during the turnover?
So now with oxygen at all depths in the water column, fish are no longer limited where they can go and look for food. The fish are now scattered and can be anywhere in the lake which can makes fishing more difficult and makes fish of all species harder to find after the fall turnover.
What does it mean when a lake or pond turns over?
Pond turnover is a term used to describe the mixing of stagnant waters in a pond. This process will often occur during the first cool days, or nights of early fall. Pond water that has sat in a pond basin throughout the hot summer months tends to stratify.

What does to turn over in the water mean?
This forces the bottom waters to the top, where they once again become re-oxygenated; when this happens, the lake is said to “turn over.” During this brief period, all levels of the lake have enough oxygen to support life, and bass could be scattered throughout any of the levels.
