Harmful algal blooms are making a strong showing in Utah this year, with more than 15 lakes and reservoirs currently under health advisories.

Utah

Utah has seen a notable increase in harmful algal blooms, with the Utah Department of Environmental Quality monitoring 52 water bodies and issuing advisories for 15 of them. The rise in blooms is attributed to a combination of factors, including higher temperatures, abundant nutrients, stagnant water, and prolonged warm seasons, which experts say are being influenced by climate change.

To help mitigate the problem, experts recommend using phosphorus-free fertilizers, reducing fertilizer use, picking up pet waste, keeping yard debris out of storm drains, and fixing leaky septic systems. These actions can help decrease the nutrient runoff that fuels algal blooms in Utah's lakes and reservoirs.

Harmful algal blooms expanding across Utah waters

Harmful algal blooms aren't new to the state. In fact the Utah Department of Environmental Quality says that the public has been much more aware of them over the past decade. Our monitoring really picked up I think around 2016 when Utah Lake had a really big bloom. Definitely put it on put it on our radar. Bailey says that the state monitors 52 water bodies for harmful algal blooms. 15 of them currently have warning advisories. It's hard to say what normal is but that it can vary year to year so it's definitely it seems like a pretty busy year this year. I think higher than we had last year. Algal blooms like the one reported here at Decker Lake back on August 22nd thrive off of several things. The sunshine we're seeing now, abundant nutrients in the water, stagnant water and hot temperatures. The Utah Climate Center says that average temperatures in the state continue to rise. What we're seeing is during our summer times our summer peak heats are starting to push up a little bit higher. Our spring temperatures are looking more like summer. Our fall temperatures are looking more like summer and so we have just more days of the year where those kind of conducive temperatures are present. So that's one of the ingredients in the algal bloom recipe that climate change is certainly affecting. Experts do provide some tips on how we can help reduce the number of algal blooms. They say that by using phosphorus-free fertilizer and reducing the overall amount we use on our lawns, picking up our pet waste, keeping yard debris out of storm drains and fixing leaky septic systems all can reduce the amount of nutrients flowing into Utah's lakes and reservoirs.
