The South Dakota Department of Agriculture and Natural Resources (DANR) is reminding the public to use caution when visiting lakes and ponds across the state.
Harmful algal blooms (HABs) can appear quickly during warm weather and may create risks for people, pets, and livestock.
Harmful algal blooms usually develop in nutrient-rich lakes and ponds during July, August, and September. However, they can appear earlier or later when weather and water conditions are favorable.
In South Dakota, HABs are commonly caused by blue-green algae, also called cyanobacteria. These organisms can produce toxins that may harm people and animals. Children can be especially vulnerable to exposure. Pets and livestock can also become sick if they drink contaminated water or come into contact with harmful blooms.
People enjoying outdoor activities around lakes should pay close attention to water conditions. Visitors should avoid water that appears suspicious and should not allow pets to drink from lakes, ponds, or other open water sources when a harmful bloom may be present.
DANR and its partners monitor lakes across South Dakota by collecting samples and checking toxin levels. The agency provides sample information through an online interactive map.
However, the sample results should not be used alone to decide whether water is safe at a particular time. Water conditions can change, and harmful algal blooms can develop rapidly.
The department encourages everyone to follow a simple safety message: When in Doubt, Stay Out! This advice is especially important for families, pet owners, livestock owners, and anyone planning water activities during the summer.
People who want more information about harmful algal blooms can visit the South Dakota DANR website. Questions about HABs and what to do after encountering one can also be directed to Joshua Strobel at 1-800-438-3367 or Joshua.Strobel@state.sd.us.
