Still Creating Polygons

My polygon layers represent the growth of the sandbars in Grand Lake between 1935 and 1973. I have over 500 objects in three layers. I'm about to start on another sandbar; the largest. It should be between 250 and 300 objects.

Also have point layers showing individual locations at different points in time, and some shoreline layers.
