Calculating Area of a Larger Polygon not Covered by Smaller Polygons

Good morning,

I am trying to calculate the area of a larger polygon that is not covered by many smaller polygons. The larger polygon is a river and the smaller polygons are SAV beds. I have tried to calculate the area but for some reason, polygons that are even a bit away from the edge are disregarded and that makes calculating the area much more difficult. Is there a parameter I am missing when using intersect? Is there a different tool I should be using? Attached is an image of what I'm working on. The black is the river and the blue polygons are the SAV beds.

Thank you for your help! I've been stuck on this for a long time now.
