Our current water level at The Alton Marina is 419.18 ft. (10′ +/-. within the harbor). 

Current USACE river forecast indicates the river will remain at stable, normal levels.  Please reference the USACE 7 day forecast below.  This is a comfortable level for us with enough water for launching, boat lift operation, and navigation into and throughout the harbor.  Barring unseasonal heavy rains or snow melt north of us, we should remain at or near full pool with consistently good water levels for the next several weeks.  We’ll keep you posted.  Safe travels!

If you have any questions, please do not hesitate to contact the Marina office at 618-462-9860.  Safe travels!
