A 53-year-old woman from Erin died at the weekend while swimming in Sparrow Lake.
Kathy Venneman was swimming with friends early Saturday afternoon, off a boat, near Morrison Landing.
She slipped beneath the water but failed to surface.
Friends and bystanders searched unsuccessfully while awaiting the arrival of the Underwater Search and rescue Unit and the Orillia OPP Marine Unit.
Her body was recovered Sunday afternoon.
