Michigan’s navigation system includes coastal
infrastructure, navigation harbors, channels,
locks, and dams. The system contains
approximately 90 harbors, 14 waterways or
rivers, the significant Soo Lock system, and
numerous disposal facilities for depositing
dredged material. Approximately 40 of these
harbors and waterways are commercial
harbors, the remainder are recreational. The
Army Corps of Engineers is provided a limited
amount of money each year from the federal
government. That amount does not meet the
annual system needs, therefore the total system
needs continue to grow each year. Because
commercial harbors are prioritized and exceed
the available funding, recreational harbors are
rarely maintained or improved.
