Cottage owners in Manitoba's Whiteshell claim a sewage lagoon has overflowed onto a popular beach and into the Winnipeg River, but the province argues it was just a trickle.
Cottagers at Dorothy Lake say the local lagoon started oveflowing at the end of July and leached under a highway before ending up in the water.
But Manitoba Conservation say there's no way the sewage reached all the way to the lake.
Department staff say there was a small overflow in July but there was nowhere near enough effluent to reach the lake or cause any water quality problems.
Manitoba Conservation has since stopped allowing sewage trucks to empty their waste in the lagoon, closed some campground showers and is checking the lagoon's levels almost daily.
