Have you noticed your favourite lake looking a little…cloudy lately? That's likely due to lake turbidity and total suspended solids (TSS), and it's more than just an aesthetic issue. These factors are critical indicators of water clarity and overall lake health.
What is Turbidity?
Turbidity is the measure of how cloudy or hazy water is. It's caused by tiny particles suspended in the water, measured using a turbidimeter. Think of it as trying to see through a foggy window versus a clean one.

What is Total Suspended Solids (TSS)?
TSS refers to the total amount of solid material floating in the water, like silt, clay, algae, and decaying organic matter. High TSS directly contributes to high turbidity—more particles mean cloudier water.
The Impact of High Turbidity and TSS on Lakes
Cloudy water blocks sunlight, hindering aquatic plant growth and impacting the food chain. Decaying organic matter (TSS) consumes oxygen, harming fish. Sediment from TSS covers spawning grounds, degrading habitats. Visually, it impacts recreation and property values. Excess nutrients from TSS can also trigger algal blooms, accelerating eutrophication. Therefore, maintaining good water quality is paramount.
Solutions for Reducing Turbidity and TSS
Identifying the source (runoff, erosion, algal blooms) is crucial. Solutions include watershed management (erosion control), algae control, and sediment removal. This is where Hydro Synergy's expertise is.
