What causes turbidity in lake?

Turbidity in lakes is primarily caused by suspended particles such as sediment, algae, and organic matter. Factors like erosion, runoff from rain or snowmelt, and human activities such as construction or agriculture can increase sedimentation. Additionally, algal blooms, often fueled by nutrient pollution, can contribute to higher turbidity levels. Turbidity can negatively impact aquatic ecosystems by reducing light penetration and affecting the growth of aquatic plants.
