CALGARY ZONE – Due to elevated levels of bacteria, Alberta Health Services (AHS) is advising the public not to swim or wade at the main beach area of Little Bow Provincial Park on Travers Reservoir, effective immediately.

Elevated levels of bacteria were detected via testing of the reservoir water at this beach location.

There is also the possibility of skin, ear and eye infections with water contact.

As always, visitors and residents are reminded to never drink or cook with untreated water directly from any body of water, including Travers Reservoir, at any time. Water-borne organisms, including fecal bacteria, can cause vomiting and diarrhea.
