Looks like a good plan . I could not tell distances from dock to main lake hump . If it is close enough to dock I would suggest that you add gravel beds to main hump. This would allow you to fish for BG/RE on beds with poles or fly rod from the dock. Also you would be able to set on dock and watch BG and Bass spawn if conditions are right.

Also I would want some cover in deep water for winter cover area and fishing and for when you have dry periods and pond is down.ewest
