Alton Marina Boat Launch Ramps Close Due to Low Water Levels
ALTON — The public boat launch ramps at Alton Marina have been closed effective July 15, 2025, due to low water levels on Pool 26 of the Upper Mississippi River Basin, marina officials announced on Tuesday. The current river level at Alton Marina is 413 feet above sea level, resulting in approximately four feet of water within the harbor. According to the U.S. Army Corps of Engineers’ latest forecast, water levels are expected to reach Maximum Drawdown within the next seven days, prompting the closure of the launch ramps to all vessels during this period. Rob Honke, operator and general manager of Alton Marina, said the marina is closely monitoring river conditions and will provide updates as they become available. “Please refer to the USACE forecast data for the most up-to-date information, keeping in mind that conditions may change with rainfall in the upper river basin,” Honke said.
