The Great Lakes have surpassed the 'high-water-level' record set 33 years ago.

Correlation != Causation
If you are looking for things "to blame" don't forget about:
-decline in religious-group (church) participation
-stagnate wage increases for 20 years while cost of living increases (result: less of an ability to afford "going out") Also related: more people needing 2+ jobs
-increased internet access/duration/interaction
All of these equate to less 'recreational' time available. Lack of recreation time = less chance to participate in social settings = more loneliness
