What happens when a lake or pond turns over?
What happens when a lake or pond turns over? Cooler weather means your lake or pond will soon turn over. 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.
How do you know if a lake is unhealthy?
The water looks cloudier than usual, is discolored, or smells bad. Cloudy water can be a warning that there are more germs in the water than normal. Discolored or smelly water could mean there is a harmful algal bloom (HAB) in the water.
What happens when a lake becomes stagnant?
Algae are tiny plants that multiply rapidly when the water becomes stagnant. Some types of algae produce toxins that can be harmful to both humans and animals. Moreover, these algae can form dense layers that block sunlight from reaching the bottom of the water.
Why do fish go to the bottom of a lake?
Because warm water sinks in very cold freshwater, fish in these water bodies often gather in groups near the bottom. Some species, like koi and gobies, may burrow into soft sediments and go dormant like frogs and other amphibians, but most fish simply school in the deepest pools and take a winter rest.
How do you know if a lake is clean?
Look for signs of poor water quality, such as algal blooms and dirty or turbid water. Do not swim in water that smells like rotten eggs or sewage. Avoid swimming near pipes that drain into lakes or streams.
How does a lake clean itself?
Turnover is like being at the mall … or at a fair. Turnover is a natural way the lake cleans up harmful bacteria and algae. It carries dead algae down into the depths of the lake where there is less sunlight, helping to prevent algae growth.
