Predators around the lake

We have had a lion attacking deer and elk around lake Granby this season with a vengeance. Today on a 3 mile stretch of the shoreline we saw 6 lion kills. Most seasons I only see 2-3 kills. I am starting to spend more time out there in lowlight conditions. It would be awesome to see a lion on the lake. Does anyone else have really cool things happen around their lakes?
