Toxic Algae Threatens Swimmers And Dogs In Virgin River At Zion
It Looks Safe, But Looks Can Be Deceiving
Few sights are more inviting than the cool waters of the Virgin River winding through Zion National Park. On a warm Southern Utah day, it's tempting to splash around, cool off, or fill a bottle from a flowing stream.
But park officials continue to warn visitors about toxic cyanobacteria that can be present in the Virgin River and other waterways. The bacteria can sometimes form mats on rocks or along the riverbed, although it is not always easy to spot.
What Exactly Is Cyanobacteria?
Often called blue-green algae cyanobacteria are naturally occurring microorganisms that can produce dangerous toxins. Even water that appears clean and clear may contain harmful bacteria.
Health experts warn that exposure can cause illness in people and animals. Pets are especially vulnerable because dogs are more likely to drink from rivers, puddles, and stream edges.
What Visitors Should Do
The safest approach is simple: don't drink untreated river water, don't submerge your head in the water, and keep pets from drinking or swimming in areas where cyanobacteria may be present. Zion National Park also recommends checking current conditions before heading out on hikes or river adventures.
Enjoy Zion Safely
The cyanobacteria warning shouldn't stop anyone from enjoying one of America's most spectacular national parks. It simply means visitors should stay informed and take a few common-sense precautions.
A little awareness can help ensure your memories from Zion involve towering cliffs, stunning views, and great adventures, not an unexpected trip to the doctor.
