President Obama allotted $475 Million for the Great Lakes. If you were in charge, what would be your top priority?

The nature of the survey doesn't allow for any cross-over.  I think that, conceptually, this is where the money is best spent; restorations and maintenance.

Restorations would cover toxic hot spots and removal of invasive species, while also addressing the needs of wetland (not just coastal, but inland as well) and riverine systems. 

A particular note about the rivers, inland lakes and wetlands; they commonly get short shrift in discussions about our region.  We should guard against any bias that negatively impacts the systems that feed into one-fifth of the world's available fresh water.  What gets protected here goes to great length to insulate damage and destruction further downstream.

The maintenance issue is a boring subject but one of equal importance.  Without the necessary funding to "shore up" (pun intended?) our failing municipal infrastructure, we fail at the source of most water-borne contamination.  This failure would negatively impact the upstream habitats regardless of the restorations made further downstream.  Maintenance of the park systems, SRAs, Wildlife zones, etc. are also necessary and often overlooked.  Increasing land area and restoration should not be done at the expense of those already existing.

No, we need some of it in all areas and we need it now!

'nuff said.
