Occurrence of water blooms in a lake indicatesa)Excessive nutrient ava...
The presence of large amounts of nutrients in waters causes excessive growth of planktonic (free-floating) algae, called as an algal bloom, which imparts a distinct colour to the water bodies. Algal blooms cause deterioration of the water quality and fish mortality. Some bloom-forming algae are extremely toxic to human beings and animals.

Occurrence of water blooms in a lake indicatesa)Excessive nutrient ava...
Excessive nutrient availability:
Water blooms in a lake occur when there is an excessive amount of nutrients present in the water. This excess of nutrients, such as phosphorus and nitrogen, can come from sources like agricultural runoff, sewage discharge, or urban stormwater runoff.
Causes of excessive nutrient availability:
- Agricultural runoff containing fertilizers
- Sewage discharge
- Urban stormwater runoff
Impact of excessive nutrients:
When there is an abundance of nutrients in the water, it leads to an overgrowth of algae and other aquatic plants. This overgrowth results in the formation of water blooms, which can be harmful to the ecosystem and aquatic life in the lake.
Consequences of water blooms:
- Depletion of oxygen levels in the water
- Blocking sunlight from reaching deeper parts of the lake
- Production of toxins harmful to aquatic organisms
Prevention and management:
To prevent water blooms in a lake, it is essential to control the sources of nutrient pollution. This can be done by implementing best management practices in agriculture, improving sewage treatment processes, and reducing urban runoff. Additionally, maintaining a healthy balance of herbivores in the lake can help control algae growth and prevent water blooms. Regular monitoring of nutrient levels in the lake can also aid in early detection and management of potential water bloom occurrences.
