Why does the Great Salt Lake smell sometimes?
Posted on Mar 20, 2026 / Travel
The Great Salt Lake can smell kind of funky at times, especially in the hot summer months, and that’s mostly because of algae and decaying organic matter. When water levels drop and temperatures rise, algae blooms can happen, which create a strong, earthy smell near the shore. Dead brine shrimp and other tiny organisms can also wash up and release scent as they break down. Wind direction and low water levels can make the smell stronger in certain areas, especially where the lake bed is exposed. While it’s a bit gross, it’s a totally natural process for a lake with such high salinity and changing conditions. Most people find the smell fades quickly once they get a bit of distance from the shoreline. Visiting at different times of day or after wind shifts can also help if the smell bothers you.
