An algal bloom in Lake Powell (right side of photo)/NPS
Algal blooms have been reported in Lake Powell at Glen Canyon National Recreation Area in Utah and Arizona, prompting a warning to visitors who might come in contact with lake water.
According to a park release, certain species of algae and phytoplankton can produce toxins that may cause illness in humans, pets and wildlife.
Algal blooms can occur for a variety of reasons. Warm, still water is the perfect breeding ground for cyanobacteria and the addition of nutrients like nitrogen and phosphorus that enter the lake from outside sources, encourage the growth of algae and bacteria, the release explained.
Some may be harmless, but you're asked to follow the following guidelines on how to stay safe during Harmful Algal Blooms (HABs).
- Don’t swim in water that has an algal bloom.
- Don’t boat, water ski, or jet-ski on scummy water. These activities can cause toxins to become airborne, increasing the likelihood you will inhale them.
- Keep children away from scum in the water or along the shore.
- Keep pets or livestock from swimming or drinking from scummy waters.
- Always take a shower after coming into contact with any surface water whether or not an algal bloom appears to be present. Rinse/wash animals immediately if they swim in scummy water and don’t let them lick their fur
