State officials are warning people visiting Herrington Lake to stay out of the water in certain areas that are experiencing a harmful algal bloom.
The Kentucky Energy and Environment Cabinet issued a warning Thursday for a harmful algal bloom at Paradise Camp, as well as at an area called Redgate, near Tanyard Branch.
“The public is advised to limit exposure to the water in these locations and to remain aware that other areas on Herrington Lake may also be experiencing a (bloom),” a news release stated.
The cabinet said drinking water that comes from Herrington Lake has not been affected “and is being closely monitored.”
The lake covers more than 2,300 acres in parts of Mercer, Garrard and Boyle counties.
The bloom activity has been going on for about a week, according to a Division of Water map that allows viewers to see reported bloom activity.
Harmful algal blooms happen when there’s an overgrowth of blue-green algae, or toxin-producing cyanobacteria. That usually happens “because of runoff from heavy rains and warm temperatures,” according to the release.
Not all cyanobacteria produce toxins, according to the state’s website on the blooms.
“HABs may appear bright green, blue-green, brown, red and/or white in color,” the state’s website on HABs says. “Some HABs may look like spilled paint, pea soup, parallel streaks and/or green dots or globs in the water. They often have a grainy, sawdust-like appearance upon closer inspection.”
The Division of Water says harmful algal blooms “are unpredictable and may develop or disappear rapidly. Any person recreating in or around water bodies should exercise their best judgment.”
In areas with a bloom, people should avoid swimming, wading, paddling and related water activities, and should keep pets and livestock away from the water too.
The state says people with asthma and respiratory allergies should keep away from areas with a bloom, and kids can be particularly sensitive.
Fish caught in an area with a bloom can be eaten, provided the fillets are rinsed in clean water that doesn’t come from the lake, the Division of Water says.
People who think they’ve seen a harmful algal bloom can report it by emailing water@ky.gov, calling 502-564-3410 or downloading the BloomWatch app.
The algae isn’t the first snag for visitors to Herrington Lake this summer.
The Cove Marina said in a Facebook post Thursday that the heavy rains have caused rising water levels and damaged the marina.
“We have lost our main walkway and the parking lot is partially gone already. No outside fishing, kayaking or guest visits will be allowed until we have additional parking,” the marina’s post stated. “We want to make sure slip renters have a place even if it’s on the hill. Thanks for your understanding, have a blessed weekend!”
