I've tried. I've found exactly zero sources claiming inuit oral traditions have accurately pointed out villages lost by floods 10000 years ago.

Which face it, would be quite impressive since they weren't even around back then. The Inuit only formed a thousand years ago, which is when they came to occupy the area they now live in. Their ancestors lived in Alaska and Russia before that, so there's literally no way for them to have an oral tradition about villages lost 10,000 years ago in the area they now inhabit. Neither could they have adapted stories from the people that lived there before (the Dorset culture), since there appears to have been no contact between these groups. Nor would that matter if they had, because none of the paleo-eskimo seemed to have existed that far back. Humans only started living in the areas the Inuit now live 5000 years ago at the earliest. So obviously they can't have oral traditions about the area that date back twice as far.

This is clearly something you either made up entirely, something someone else made up, or a case of you misremembering something you read.
