The case went to court because the potential claimant (Nicola Fish and Game) wanted the costs covered by the Province. The judge said no and the case presented by NFG looked to many as kind of specious. The billionaire in the story, Stan Kroenke, does not own all the land around Corbett Lake and hasn't denied access to that lake to anyone. The public access was closed by the previous owner of the Corbett Lake Country Inn in the early 90s'. Likewise access to Minnie and Stoney was blocked by Douglas Lake Cattle Ranch in the 70s when it was owned by Chunky Woodward. Both lakes were fish-less at the time as the BC Fish and Wildlife Branch stopped stocking them as they frequently winter and even summer killed. Both were known to grow large trout quickly if they fish survived for a year or 2.
The lakes were developed as private access fisheries in the early 80s by DLCR - who made the changes necessary for the lakes to support fish and stocked them privately. This included raising the level of the lake by installing catch dams. In cases where ponds or lake are raised or created by dams installed by private landowners the province accepts the resulting lake bed is not public land but is private as is the lake shore. No fisheries easement is required as NFG seems to suggest.
