PICTURES: Dead fish found floating along Jordan River

LEHI, Utah (ABC4) — On Friday morning, about 50 dead fish were found floating on the surface of the Jordan River in Lehi.  

John Mackey, Director of the Division of Water Quality said they sent out their scientists after they received a report of several dead fish floating on the river.

While the investigation is still in its early stages, Mackey indicated that the warm temperatures make such events likely during this time of year. They also recorded low oxygen levels in the water, which can be harmful to fish.  

“The most common reason for fish kill is high temperatures and low dissolved oxygen” shared Mackey.

Additionally, Mackey pointed out that there is a significant algae bloom occurring in Utah Lake, which flows into the Jordan River. A large number of algae is entering the Jordan River, particularly in the area where the dead fish were discovered.

Currently, there is no exact answer. However, Mackey shared that all these factors could contribute to the issue. 

Exercising caution at the river

Mackey advises residents to exercise caution when engaging in recreational activities on or near the river. He shared that the Division of Water Quality regularly monitors various beaches along the river during the algae bloom season.

If toxins are detected, advisories and notices about potential threats are posted on the division’s website as well as on the websites of multiple local health partners. It is important to pay attention to these warnings and stay informed about river conditions. 

“If you notice scum and heavy green floating material, and even just really green water, check the websites” shared Mackey.  

Mackey added the importance of being cautious not only for humans but also for pets, as they are particularly susceptible. He suggested that pets should be kept away from the water. The public should remain aware and exercise caution. While boating and fishing are still permitted, Mackey recommended avoiding bathing in the water, as it is currently unsafe.
