TOPEKA, Kan. (KAKE) - The Kansas health and wildlife departments have issued blue-green algae warnings for twelve bodies of water, and six are under a watch.

The current list of warnings include:

  • Overbrook City Lake,Osage County
  • Colwich City Lake, Sedgwick County
  • Crystal Lake, Anderson County
  • Ford County Lake, Ford County
  • Gathering Pond, Geary County
  • Hain SFL, Ford County

  • Kingston Lake, Johnson County
  • Melvern Outlet (River) Pond, Osage County
  • Milford Lake Zone C, Geary and Clay County
  • Rooks County SFL, Rooks County
  • Summercrest Lake, Johnson County

When a warning is issued, KDHE recommends the following precautions be taken:

  • Lake water is not safe to drink for pets or livestock.
  • Lake water, regardless of blue-green algae status, should never be consumed by humans.
  • Water contact should be avoided.
  • Fish may be eaten if they are rinsed with clean water and only the fillet portion is consumed, while all other parts are discarded.
  • Do not allow pets to eat dried algae.
  • If lake water contacts skin, wash with clean water as soon as possible.
  • Avoid areas of visible algae accumulation.

A watch means that blue-green algae have been detected and a harmful algal bloom is present or likely to develop. People are encouraged to avoid areas of algae accumulation and keep pets and livestock away from the water.

The following six bodies of water are under watch:

  • Lake Scott State Park, Scott County
  • Louisburg Old Lake (City Lake), Miami County
  • Marion Reservoir, Marion County
  • Milford Lake Zone A, Dickinson County and Geary County
  • Milford Lake Zone B, Geary County
  • Carbondale city (Strowbridge), Osage County

Kansans should be aware that blooms are unpredictable. They can develop rapidly and may float around the lake, requiring visitors to exercise their best judgment. If there is scum, a paint-like surface or the water is bright green, avoid contact and keep pets away. These are indications that a harmful bloom may be present. Pet owners should be aware that animals that swim in or drink water affected by a harmful algal bloom or eat dried algae along the shore may become seriously ill or die.
