4.4 Public Health

Goal 4 - Public Health

Minimize the risks of threats to public health through the development of programs, plans and policies that improve the quality of surface and groundwater resources. 

Discussion

There are several potential threats to public health in the Christmas Lake subwatershed.  Sewage overflows from breaks or improperly functioning infrastructure could result in overflows discharged to downstream water resources.   An additional potential source of pathogens is waterfowl, which are attracted to open water with easy routes from the water to vegetation on shore.  The District’s role in minimizing the threats to public health in the subwatershed is mainly to provide targeted information to landowners and LGUs.

Desired Outcomes:  Minimization of threats to public health from contact with contaminated surface waters.

Metrics:  Reported cases of illness transmission via surface water contact.

Goal 4.1 - Christmas Lake 

Minimize risks to human health and water quality from land use activities.

Actions

  1. Maintain Christmas Lake in-lake total phosphorus concentration goal.
  2. Inspect the channel draining the upper subwatershed at least annually to assess whether erosion is occurring.
  3. Work cooperatively with the City of Chanhassen to manage flows in the channel to prevent erosion and sediment transport and stabilize streambanks as necessary.

Goal 4.2 - Christmas Lake 

Maintain a vegetated shoreline on Christmas Lake where practical and effective to reduce overpopulation of the lake with waterfowl.

Actions

  1. Conduct a shoreline vegetation survey to identify current shoreline status and to identify locations where restoration may be desirable and feasible.
  2. Promote native vegetation over structural shoreline stabilization where practical and effective in District policies, regulations, and programs.
  3. Work cooperatively with LGUs and property owners to restore native shoreline vegetation where appropriate.
    1. Provide education and training opportunities, technical and planning assistance, and demonstration project funding to LGUs to assist them in restoring shorelines and buffers on public property such as parks and open spaces, taking into consideration the balance between recreational use and ecosystem needs.
    2. Develop and distribute written material to shoreline property owners explaining the benefits of shoreline restoration and buffer creation to waterfowl control and providing design, plant selection, installation, and maintenance advice.

Goal 4.3 - Christmas Lake  

Require LGUs and other agencies to manage public sanitary sewer infrastructure to minimize sewage overflows and to minimize impacts from those overflows on District water resources.
