Prolonged cloudy weather, drought conditions, overcrowded fish populations, excessive algal or other plant growths, and high water temperatures are the most common factors that combine to cause fish kills..
What happens to fish when a lake turns over?
Above the thermocline – in the warmer layer that fish biologists call the epilimnion – fish survive comfortably in the oxygen-rich water. Below that line (the hypolimnion) low oxygen levels discourage fish from living there. … When a lake turns, the surface water falls and the now-warmer water from the bottom rises.
Where do fish come from in lakes?
When fish are delivered naturally Many lakes and ponds are formed by rivers and seas themselves. For instance, if there is a steady upsurge of water in a lake, its water might ‘spill’ over its natural boundaries and accumulate in a low-lying area via small streams.

At what point is a pond a lake?
Ponds, on the other hand, have a more consistent temperature throughout. If the water is deep enough that light does not penetrate to the bottom, and photosynthesis is limited to the top layer, the body of water is considered a lake. A pond is a body of water shallow enough to support rooted plants.
What kills the most fish?
Of known causes, fish kills are most frequently caused by pollution from agricultural runoff or biotoxins. Ecological hypoxia (oxygen depletion) is one of the most common natural causes of fish kills. The hypoxic event may be brought on by factors such as algae blooms, droughts, high temperatures and thermal pollution.
How do lakes die?
