2) The northernmost bay of Sturgeon where the Deax and Pickeral rivers enter is called Biodiversity bay on some old maps.

Back in the logging days, there was a wooden dam at the Sturgeon outlet. It was later destroyed when logging was banned and the wilderness park was created. I've read that one can still see the remains with a sharp eye. I've never looked for it. It no longer affects water levels on Sturgeon or anywhere else. My understanding is that it helped with water levels on Bentpine lake and creek. There are logging relics there, so maybe that's where the dam was? Or were there dams in both locations?

Two more questions? Or three? 8-)
