How do you tell if a lake is turning over?
When a lake turns over, what is happening is that the cooler water on the bottom of the lake will mix with the warmer water at the top of the lake for a brief time period. In most cases you will periodically see small bubbles coming from the bottom all the way to the surface.
What time of year does a lake tend to turn over?
Whenever we get close to the colder months of the year, every experienced angler starts to mention the term 'lake turnover' more and more often. But what does it mean, and why does a lake turn over? This process usually takes place when we leave the warm summer months and the temperatures begin to drop.
At what temperature does a lake turn over?
Thirty-nine degrees F, or roughly 4 degrees Celsius is a critical value to stratification, lake mixing and turnover. Four degrees Celsius is where water reaches the point of maximum density. When water reaches this point, it sinks to the bottom of the lake.
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 is lake turnover and why is it important?
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 does it mean when a lake turns?
Simply put, lake turnover is the seasonal mixing of the entire water column. For many lakes deeper than about 20 feet, distinct, thermally stratified layers of water form during the summer. These layers prevent the lake from mixing and aerating.
Does a lake turnover in the winter?
Each year, Mother Nature renews the health of our lakes by a process of mixing, called turnover, which occurs two or more times a year depending on the depth of a lake. The season, the creeks, rivers and the wind are all involved.
How do you fix a pond that turns over?
One way to fix a pond that has turned over is through constant aeration. Aeration mechanically incorporates air into the water which consequently adds oxygen as well. Aeration can come in many forms but most commonly it's accomplished by using a pump or a fountain.
What happens to a pond when it turns over?
The end result of a pond turnover can cause an algal bloom die off, a fish kill, or both. Preventing pond turnover, in addition to harvest considerations, are the primary reasons most fish culture ponds are constructed with shallow depths.
What causes a pond or lake to turn over?
Cooler weather means your lake or pond will soon turn over. As the surface water begins to cool in the fall, it eventually equalizes in temperature with the deeper water. When this happens the entire water column will mix or “turnover”.
What turnover means?
Turnover is the total sales made by a business in a certain period. It's sometimes referred to as 'gross revenue' or 'income'. This is different to profit, which is a measure of earnings. It's an important measure of your business's performance.
Why is lake overturn important?
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 it called when a lake turns over?
It's called lake turnover. This phenomenon is actually good for our lakes, although you might not enjoy the smell that it causes. Just like the air, cold water sinks and warm water rises. During the summer the surface of the water is the warmest and the deeper you go the colder the water gets.
What does it look like when a pond turns over?
In general, you can tell if a pond has turned over when the water suddenly becomes murky, there is a sulfur like smell and the fish are dead or gasping for air at the surface. Pond turnover occurs when toxic, decayed matter at the bottom of a pond rises to the top due to a sudden change in temperature.
What causes a pond to turn over?
As the surface water begins to cool in the fall, it eventually equalizes in temperature with the deeper water. When this happens the entire water column will mix or “turnover”. As a result, the bottom sediments are stirred and anaerobic conditions are mixed throughout the entire pond for a period of time.

What is overturn in water?
The almost spontaneous mixing of all layers of water in a reservoir or lake when the water temperature becomes similar from top to bottom. This may occur in the fall/winter when the surface waters cool to the same temperature as the bottom waters and also in the spring when the surface waters warm after the ice melts.
What does it mean when a pond flips?
Pond turnover happens when the water in the pond literally “turns over” and the cold water at the bottom rises to the top. This usually happens due to sudden temperature changes such as cold rains or wind which causes the water at the top to sink to the bottom.
