Could you (If you tryed again) ask it it it is the same creature(s) as Ogopogo? That would be quite interesting. Its supposed to be another mysterious
lake creature that lives in hte OAKANAGAN lake (close, Pisky

). There are MANY sighting and rumours about it, thought it has never gained the
popularity of the loch ness monster.
The natives would always throw sacrafices into the water before crossing the lake, because many lives have been claimed by a "lake demon" (hence the
name, Ogopogo).
One story I found very odd was the one where some guy was taking his horses across the lake, when suddenly they were pulled underwater. For fear of
his own life, he cut the horses loose. No remains where ever found.
Heres a good link for sightings of Ogopogo
