What is the advantage of turnover in tropical lakes?
In freshwater lakes, the spring and fall turnovers are important processes that take place. It helps to move the nutrients and oxygen at the bottom of deep lakes to the top.
What is lake seasonal turnover?
Turnover is a phenomenon that occurs in terrestrial bodies of water, such as lakes and ponds, in which the water near the surface of the lake (epilimnion) is replaced with the water near the bottom of the lake (hypolimnion) to establish a homogenous mixture.
What causes a lake to 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.
What is lake stratification and how does it relate to seasonal turnover?

Fall turnover occurs when the surface water begins to cool and sink aided by
What is lake turnover and why is it important?
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.
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.
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.
Why is lake stratification important?
Stratification has important implications for fisheries management, phytoplankton (algae) populations, and water supply quality. A discussion of a few stratification impacts follows. Just after summer stratification is established, the hypolimnion is rich in dissolved oxygen from the early spring mixing of the lake.
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.
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.

What happens when a lake turns over?
Shallow lakes will often times not turn over while large deep lakes may only turn over in certain parts of the lake. If the turnover happens very quickly it can cause problems, even fish kills, because it can deplete the oxygen in the levels of the lake where the fish currently reside.
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 happens to a lake when it turns over?
Shallow lakes will often times not turn over while large deep lakes may only turn over in certain parts of the lake. If the turnover happens very quickly it can cause problems, even fish kills, because it can deplete the oxygen in the levels of the lake where the fish currently reside.
What is the significance of stratification in lakes?
Stratification is defined as the development of relatively stable light and warm layers above colder deeper layers within a body of water. Thermal stratification is related to water density and is effected by incoming heat, water depth, and the degree of water-column mixing.
Why is a turnover called a turnover?
turnover (n.) also turn-over, 1650s, "action of turning over," from the verbal phrase; see turn (v.) + over (adv.). As a kind of pastry tart, from 1798.

What is turnover in a pond?

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.
How does 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 does turnover mean in fishing?
Here's a simple definition: Turnover is the period of time when the lake is circulating from top to bottom and the water temperature is uniform throughout.
What are temperate lakes?
Lakes in the temperate zone have a general seasonal pattern of thermal stratification. During the summer months, the upper two meters of lake water will absorb more than one-half of the sun's radiation and will be warmed. A typical summer stratification has three distinct water layers.
What is turnover in ecology?
Turnover refers to intervals of increased rates of taxon gains and/or losses, as a result of which the fauna or flora after the interval significantly differs from the ones before. Immigrations and/or speciation are responsible for the gains, emigration, and extinction for losses.
Why is increasing revenue important?
You invest your time, energy, and money to make profit. The primary driver of profitability is revenue. The more you grow revenue the more likely you are to grow profits. If you achieve higher levels of revenue and manage costs so they rise at a lower rate, then you maximize profits.

It is caused by changing temperatures in surface waters brought on by the progression of the seasons. In Arkansas' continental-temperature climate, most ponds and lakes turn over in both the fall and spring. Turnover occurs in the fall when surface waters cool, and in the spring when they warm-up again.
Why turnover is an important issue?
A higher turnover rate can reflect higher profitability, while a low turnover rate can reflect lower profitability.
