In-Stream Habitat Alteration

In-Stream Habitat Alteration refers to lost in-stream habitat due to human modification of a waterway’s bed, banks, or flow. Modification of a stream’s bed or banks happens when streams are channelized, sent through culverts, dammed, dredged or filled. Out of stream infrastructure, such as curbs and gutters, storm-drains, and concrete ditches alter the rate of flow that enters a stream, quickly ushering water off impervious surfaces and sending it rushing into the stream channel. These modifications to streams result in an alteration of in-stream habitat.

Habitat alteration can disrupt native species reproductive cycles or simply make living conditions untenable for some aquatics, reducing taxonomic richness and diversity. It can also lead to the replacement of native species by exotic or invasive species or provide advantages to generalist species over specialist species.

  • Adopt

  • Remove unused dams.

    If you have an antiquated or unneeded dam on your property, contact the Cumberland River Compact to discuss the feasibility of removing it. Walk the stream and inventory the location of any dams or obstructions, and let the Compact know so we can add these to our database or potential removal projects.

    Resources include:

    • Dam Inventory, Removal and Stream Restoration – Cumberland River Compact
    • How Dams Damage Rivers and How Dams are Removed – American Rivers
  • Reduce paved, impervious surfaces

    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.

  • Allow for natural growth near waterways

    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.

    Resources include:

  • Plant a rain garden

    Rain gardens can filter and infiltrate stormwater that flows across your yard.

    Resources include:

  • Make your voice heard and your vote count.

    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.

    Resources include:

    • Advocacy Toolkit – TN Environmental Council
    • Find Your Legislators – Federal Legislators; State Legislators (KY/TN); Local Legislators (KY/TN)
  • Spread the word.

    Do your neighbors, family, or roommates know about the problem? Now that you know how to be an effective steward, enlist the help of others in your neighborhood. Share iCreek or resources within it with your neighbors and encourage them to join the effort to protect your creek.
