PIGEON LAKE, AB — Residents and visitors at Pigeon Lake southwest of Edmonton are being warned not to drink water or swim following the discovery of blue-green algae.
That’s threatening to ruin holiday plans and business, but a planned Ma-Me-O days sandcastle building contest Sunday is scheduled to go ahead.
Pam Elgert, a waitress at Daisy McBeans, worries another blue-green algae advisory, which was issued for the popular spot for much of last summer, will keep customers away again.
Daisy McBeans is a coffee and ice cream shop near Ma-Me-O beach on Pigeon Lake. “It’s not hurting us now, but when people can’t come and swim it has an impact,” Elgert said.
Her own plans to spend next weekend at the beach with her 10-year-old daughter and seven-year-old son will likely change, too. “We were planning on going swimming for the long weekend but if we can’t go in the water, we won’t be going.”
Alberta Health Services issued the advisory late Friday for Pigeon Lake, located about 100 kilometres southwest of Edmonton. Dr. Marcia Johnson, a medical officer of health for the Edmonton Zone, said signs warning of the algae’s presence were being posted around Pigeon Lake’s shore on Saturday morning.
Johnson said people and pets should not swim or wade in the lake, and recommended people may wish to limit their consumption of fish from the lake, because of the toxins produced by blue-green algae.
People or pets who drink or swim in the contaminated water could get sick. Symptoms range depending on the amount of blue-green algae a person or animal has been exposed to. Symptoms include skin irritation, rash, sore throat, sore red eyes, swollen lips, fever, nausea and vomiting or diarrhea.
“Unfortunately blue-green algae is developing a pattern of occurring in many lakes in Alberta,” Johnson said. “It’s related to water temperatures and the level of nutrients in the water.”
Pigeon Lake will be monitored regularly and the advisory will be lifted when there is no remaining sign of blue-green algae.
The advisory comes a week after hundreds of whitefish washed ashore at Ma-Me-O beach at Pigeon Lake.
Dave Ealey, spokesman for Alberta Environment and Sustainable Resource Development, said at the time hot weather was to blame, rather than toxic blue-green algae.
“We’re still convinced that the temperature was the concern for those fish,” Ealey said Saturday.
Glenn Isaac, executive director of the North Saskatchewan Riverkeeper Program, said in an email a blue-green algae advisory was issued on the same day last year.
The advisory and dead whitefish made for “a tough week for those of us who love Pigeon Lake,” he said.
For 17-year-old Hayley Buskas, who lives in Edmonton and spends time at her parent’s cabin at Pigeon Lake, algae advisories are becoming a normal part of summertime.
Buskas helped organize events for this weekend’s Ma-Me-O Days, including a pancake breakfast and parade. She said a sandcastle building contest scheduled for Sunday would go ahead as planned, as the dead fish from the beach had been removed by a volunteer cleanup crew.
“We seem to have an algae advisory every year. It doesn’t affect me, I’m still boating and swimming,” she said.
Two other blue-green algae advisories remain in effect for lakes in the Edmonton area.
A blue-green algae warning was issued on July 24 for Lac Ste. Anne, a lake about 75 kilometres northwest of Edmonton where, days earlier, people had waded into the water to offer their prayers at an annual religious pilgrimage.
An advisory was issued for Lake Isle, located northwest of Edmonton, on July 10.
