Introduction
Located in the southeastern United States, the mighty Mississippi River is among the world’s great rivers. From its source at Lake Itasca in northern Minnesota to the Gulf of Mexico, it forms the world’s fourth-longest river system. It is an important transportation artery and provides a unique form of cultural expression, with many settlers and farmers making their way along it. Memphis, Tennessee, is located near the Mississippi River and the current stage of the river in the area is determined by a number of factors.
Factors Affecting the Stage of the Mississippi River in Memphis
The stage of the Mississippi River in Memphis is dependent on several key factors. These include upstream rain and snowmelt runoff, upstream impoundment operations, upstream floodplain storage, local rainfall, and river channel and levee modifications. Rainfall from upstream regions, such as Minnesota and Wisconsin, contributes to the river’s stage in Memphis. In addition, impoundment operations from upstream regions, such as dams, can affect the flow of the river, resulting in a change in the stage of the river in Memphis.
Impacts of the Mississippi River Stage in Memphis
The stage of the Mississippi River in Memphis is closely monitored and has an impact on the area’s economy. Changes in the stage of the river can affect the number of ships that are able to safely navigate it at any given time, which in turn can have an effect on shipping and commerce. Furthermore, a high stage of the river can cause flooding, putting homes and businesses at risk.
Measuring the Mississippi River Stage in Memphis
The stage of the Mississippi River in Memphis is measured using a gage that is operated by the U.S. Army Corps of Engineers. The gage measures the stage, or height, of the river by looking at the level of water at a fixed point on the river. Changes in the gage height can be monitored in real-time, allowing stakeholders to quickly respond to changes in the stage of the river.
Monitoring Practices and Protocols
The Mississippi River stage in Memphis is important to monitor year-round. The U.S. Army Corps of Engineers uses a variety of techniques to stay informed about the river’s stage, including remotely operated cameras, radar, automated river gage readings, and manual observations.
Current Mississippi River Stage in Memphis
As of June 2021, the Mississippi River stage in Memphis is at 8.37 feet. This is well below the flood stage of 34 feet, and is considered normal for this time of year. The level is monitored daily and any changes in stage are recorded and made available to the public.
Conclusion
The Mississippi River stage in Memphis is an important factor to monitor. It can have an effect on the local economy and can also be used to predict potential flooding. The U.S. Army Corps of Engineers monitors the stage on a daily basis and can provide information about current and expected stages of the river.
