Heavy Rain Effects on St. Louis Rivers and Sewer System

Estimated read time 4 min read

Tuesday saw substantial rain in St. Louis, causing local rivers and the storm sewer system to be affected. The Mississippi and Missouri rivers experienced a significant rise, reaching minor flood levels. However, St. Louis’s Metropolitan Sewer District (MSD) only received about 40 call alerts by Tuesday afternoon, showing that they could handle the situation.

 

Drain Blockages and Local Flooding

Sean Stone of MSD Project Clear pointed out two main problems, storm drains being blocked and water buildup in low street areas. Debris impedes water flow into the sewer system, but MSD workers are clearing these blockages. Stone said slow rainfall over time helped the system process water more efficiently than during heavy, sudden showers.

Rising River Levels and Safety Measures

The Mississippi and Missouri rivers have reached minor flood levels due to excessive rain. The U.S. Coast Guard advised leisure boaters to stay away from the Mississippi River around St. Louis city area. Lt. Eric Kiehlmeier highlighted risks from the swift river currents and its debris, mentioning that breaking boating restrictions could risk lives of both boaters and rescue staff.

Flooding Updates

The U.S Army Corps of Engineers stated that the Missouri River had reached its highest point but was now falling back, while we can expect the Mississippi River to crest soon. High water flow has made the river risky particularly for small boats due to visible and underwater debris.

Different Flood Alerts

The National Weather Service (NWS) released several flood alerts for St. Louis region such as warnings, advisories and watches. Here is what residents need to know,

  • Flood Watches show conditions are right for flooding which helps people get ready.
  • Flood Advisories show expected flooding that might disrupt day to day life but won’t significantly endanger life or property.
  • Flood Warnings are for severe floods which are serious and can harm people and property.

Different Flooding Types

  • Flash Flooding refers to floods happening within six hours of heavy rainfall often affecting small creeks and low areas quickly.
  • Areal Flooding refers to slow developing floods caused by continuous moderate rain leading to water accumulation in flood prone areas.

 

Recent Flooding Events

The remnants of Tropical Storm Beryl led some regions in Southern St. Louis County such as close to Meramec Bottom Road and Hawkins Fuchs Road, experienced flooding. Heavy rainfall on Tuesday delayed the declining river levels on the Missouri and Mississippi rivers causing minor new rises.

Tips for Areas Prone to Flooding

Six inches moving water can easily knock a person down. Two feet of floodwater can make a car float. Fastmoving water at two mph can sweep a car off a road or bridge. Residents should avoid going through flooded areas. If you come across rising water, find another route instead. Do not attempt to cross barricades set up for protection from risky roads.

 

Getting Ready for Floods

Stay informed through radio, TV or use the National Weather Service radio for regular updates. In case of floods get to higher ground ASAP. Don’t Park cars near streams in case of flood warnings. A “Go Bag” is recommended that should include essentials like important papers, extra keys, previous cards, money, bottled water, nonperishable food items, flashlight, battery powered radio, medicines and childcare supplies.

 

Safety While Traveling During Floods

The Missouri Department of Transportation (MoDOT) gives advice to travelers, Stay updated with weather updates. Avoid low lying streets and flood favored areas. Never cross roads covered by water whether walking or driving. If barricades or water blocks your way turn around and find another route. Leave cars behind if they get stuck in rising water and find safer higher ground.

 

The Conclusion

Recent heavy rainfall has greatly affected St. Louis’s local rivers and sewage systems. While the situation is currently under control, residents need to stay updated and take necessary precautions for their safety. Pay attention to flood alerts and warnings and plan travels accordingly. By following safety measures and being prepared the community can better face the risks associated with heavy rainfall and floods.
