Calgarians hoping to beat the summer heat at Sikome Lake had to be turned away Saturday after a power outage shut down the pumps and filtration system at the man-made lake.
ENMAX says residents in the area are not impacted by the outage.
However, crews will need the afternoon to get everything back up and running.
It's expected the facility will be able to open on Sunday.
Officials say wildlife activity, possibly nesting, is suspected as being the cause of the outage.
