Low water levels in Utah Lake’s marinas have fallen below 50-percent at Utah Lake State Park in Provo on Wednesday, June 29, 2016.

PROVO — Utah environmental officials say toxin levels in Utah Lake are on the decline.

The Daily Herald reports (http://bit.ly/2ck0xvU ) that the Utah Department of Environmental Quality says samples collected this month at the lake and the Jordan River show cyanobacteria cell counts and toxin levels decreasing.

Cyanobacteria is commonly known as blue-green algae.

Health officials closed Utah Lake after an algal bloom was noticed in July. The bloom has since decreased and then re-emerged.

Environmental officials say they did not detect any cyanotoxins in samples collected Sept. 6. Cyanotoxins can be harmful to humans and animals.
