Turbidity

Turbidity is the relative transparency of a fluid, in this case, surface water. The transparency depends on the amount of suspended particles in the water, so the measurement of turbidity is closely linked to total suspended solids. The particles suspended in the water can be almost anything, from silt to precipitated chemicals.

When surface water is turbid, less light enters the water, and aquatic plants cannot perform photosynthesis and less organisms can survive, thus lowering the productivity of the ecosystem. Turbidity is also linked with low dissolved oxygen, colder temperatures, harmed gill function, and degraded spawning areas. Fine particles can kill fish directly, as well.

How You Can help

Are you a member of a group or organization in your community that would be interested in adopting this waterway? Contact the Cumberland River Compact if you’re interested in learning more about stream adoption.

Excluding farm animals from this waterway and providing them with alternative sources of water can prevent animals from trampling streamside vegetation and defecating in the waterway.

If you live or work next to a waterway, leave a 35′ to 100′ no mow zone on its banks. Allow natural and native plant growth in this buffer area or plant native trees, bushes, and groundcover. This vegetation can filter pollutants before they reach your waterway and provide other water quality benefits that far exceed those of a mowed lawn. Native plants and grasses require less watering and fertilizer and also provide important habitat for native species of wildlife.

Impervious or impermeable surfaces, like pavement, contribute significantly to polluted stormwater runoff and alter stream flow habitat. If you've got excess pavement you'd like removed, consider a de-paving project with the Compact. Elsewhere, ensure that your downspouts drain to vegetation, gravel, or rainbarrels, rather than impervious surfaces. If you constructing or repairing your driveway, pervious pavement allows stormwater to infiltrate and filter through the ground. If you can’t do the whole drive, consider making only the portion closest to the street pervious.

Participate in community planning efforts and advocate for relevant measures that improve or protect water quality. Write to your elected official and let them know this is concern or invite them to speak about the impairment with your home-owners association. When elections come up, vote for candidates who will address the problem and hold them accountable to their promises. Support local watershed / environmental associations.
