URGENT NOTICE: LAKE CLOSED UNTIL FURTHER NOTICE

​​

Effective immediately, Lake Chaparral is CLOSED to all recreational water use following an unsatisfactory water quality test result. Red flags are currently flying. Please DO NOT enter the water.

​

A routine water sample was collected on Tuesday, August 25, and the Lake Chaparral Residents Association was notified of the unsatisfactory Enterococcus bacteria result on Friday, August 28. Upon receiving notification, the lake was immediately closed to recreational water use.

​​

The water sample collected on August 25 returned an Enterococcus result of 8,043 CCE per 100 mL.

​

The laboratory report states that results of 6,400 CCE per 100 mL or greater represent significant fecal contamination, regardless of the source, and the water quality is considered unacceptable.

​

As a result, the lake will remain closed to recreational water use while follow-up testing is completed.

​

Follow-up sampling is scheduled for Monday August 31st. The lake will therefore remain closed for the entire weekend. We will provide an update once additional results and information are available.

​

Residents who have used the lake since Tuesday August 25th and have concerns about their health or are experiencing gastrointestinal illness, or skin, ear or eye irritation, should contact Health Link at 811 or their healthcare provider for advice.​

​

Main Park Remains Open​

​

The park and land-based amenities remain open seven days a week from 9:00 a.m. to 10:00 p.m. However, all recreational use of the lake is prohibited until further notice.

​

We are working directly with Alberta Health Services regarding follow-up testing and will provide updates as soon as additional information becomes available.

Thank you for your cooperation.
