Utah Lake: Unsafe for Swimmers, Beware Algae Blooms
15 Dec
Summary
- Utah Lake remains unsafe for swimming due to persistent harmful algae blooms.
- Algal toxins can cause severe health issues in humans and pets.
- Monitoring for e.coli and algae risks continues; advisories are issued.
Utah Lake faces persistent challenges from agricultural and industrial pollution, leading to its current reputation as one of America's dirtiest lakes. Recurring harmful algae blooms (HABs) thrive in its shallow, nutrient-rich waters, altering the water's color and releasing toxins dangerous to human and animal health. These toxins can result in various ailments, from rashes and vomiting to more severe conditions.
As of late 2025, state officials, including the Utah Department of Environmental Quality, continue to issue warnings regarding swimming safety. The latest advisories confirm the presence of harmful algae lakewide, posing risks to visitors. While monitoring has been suspended until mid-2026, caution is still advised, with the state's Division of Water Quality collaborating to manage the situation and provide timely health advisories.
Despite the swimming advisories, Utah Lake still offers opportunities for enjoyment through activities like birdwatching, boating, and fishing. However, visitors are strongly urged to avoid swimming or wading and to exercise caution. Even when advisories are lifted, showering afterwards is recommended, and drinking the lake water should always be avoided.
