These are some lakes you might want to avoid do to Toxic algae bloom.
http://www.thenewstribune.com/news/local/story/176383.htmlI also included the list of what causes this I like the fact that #1 is restore plants so next time we see home owners out there ripping out all the lily pads we can inform them what the result will be.
Algae blooms are likely to occur during sunny, calm weather when high concentrations of nutrients are present in the water. People can have a big effect on the amount of nutrients in a lake. Two important nutrients algae require are phosphorous and nitrogen. These are found in animal and human waste (sewage) and in fertilizers. Excessive amounts of nitrogen and phosphorus may lead to "nutrient loading" and eventually to an algae bloom. To help decrease nutrient loading:
1. Maintain or restore native plants around lake shorelines and streams that feed the lake. Native wetland plants help filter water and don't require pesticides or fertilizers for maintenance.
2. Be extremely cautious with lawn and plant fertilizers and pesticides. Don't over-water, over-fertilize, or use more than the recommended amount of pesticides.
3. Improperly operating or damaged septic systems are a major cause of nutrient loading into nearby water. Proper care and maintenance of your septic system are essential. For information on how to maintain your septic system please call the health department at 253-798-6470.
4. Prevent surface water runoff from agricultural and livestock areas. Do not allow livestock to drink or defecate in streams or lakes. Don't feed waterfowl.
5. Take steps to prevent erosion around construction and logging operations. Erosion can carry nutrient-rich soil into nearby lake
