CyanoAlert – Lost Creek Lake

21 June 2011

Lost Creek Lake is back on the alert list again. A health advisory has been issued to avoid contact with the water at Lost Creek Lake on the Rogue River 30 miles northeast of Medford because of a bloom of toxin-producing blue-green algae.  This article includes a useful summary of the things to look out for in a lake that contains toxic algae.  Beaches at Buckeye Lake remain off-limits.

The very toxic bloom that occurred in the Solomon’s Islands Marovo Lagoon appears to have dissipated.

With the current hot weather in the area, the Haliburton, Kawartha, Pine Ridge District Health Unit warns conditions are ideal for the formation of blue-green algae. This is especially true in lakes and reservoirs with shallow, slow-moving or still water that is rich in nutrients.

We need to keep reminding people how damaging excess phosphorus in lakes and dams can be.  When you use too much of fertilizers in the soil, it leads to eutrophication. Fertilizers contain substances like nitrates and phosphates that are flooded into lakes and oceans through rains and sewage. These substances prove to become toxic for the aquatic life, thereby increasing the excessive growth of algae in the water bodies and decreasing the levels of oxygen. This leads to a toxic environment and leads to fish kill and death of other aquatic fauna. Indirectly, it contributes to an imbalance in the food chain as fishes tend to be the main food source of various birds and animals in the environment. You would be surprised to know that more than 50% of the lakes in the United States are eutrophic! (or, if you have been paying attention to this blog, you wouldn’t be!).
