Shoreline Improvement

Introduction by Bruce Carlson (October, 2009)

The TMLA is working on a long-term program of active preservation of both Ten Mile Lake and its watershed and using what is learned as a demonstration project that other lake associations and agencies might want to learn from. Keep tuned for information about specific projects and proposals for funding them.

Shoreline Improvement Program Outline

  1. Photographic survey of entire shoreline- Contract with DNR personnel.
  2. Publicity campaign to Ten Mile residents
    1. Raise consciousness about project
    2. Education
    3. Peer pressure
  3. Select some demonstration projects - do in advance of proposal?
    Types of shoreline issues :
    1. Shoreline erosion
    2. Riprap - improving environmental quality
    3. Lawns
    4. Aquatic vegetation/docks?
    5. Angel Island causeway
  4. Carry out demonstration projects
  5. Report results at annual TMLA meeting, Website photos, Newsletter, etc.
  6. Increase number of projects
  7. Quantifying and reporting results
  8. Sharing results with other lake associations (education effort)
