Boaters and swimmers have been advised to use caution during activities on the Ohio River following the discovery of more blue-green algae blooms.
The Wheeling-Ohio County Health Department re-issued a health advisory after algae blooms were found on Wednesday near the back channel of Wheeling Island and near McMahon Creek.
The health advisory initially was issued after water tests on Aug. 19 showed elevated levels of blue-green algae at the Pike Island Lock and Dam. Wheeling closed its water intake and operated with wells through Aug. 21.
The city will monitor water taken from the river but doesn’t plan to close the intakes because of the latest algae blooms.
