	A convention of nine states attended a convention in Burlington, Iowa on October 24, 1851. Representatives of the states of Iowa, Illinois, Wisconsin, Missouri, and the Territory of Minnesota affirmed the value of the Mississippi as a "great national highway" and that it was up to the "National Legislature" to make such improvements to it that midwestern states could compete for commerce with those states in the east. It was resolved that Congress should make appropriations for the removal of obstructions in the river. Those in attendance planned to meet again the next year.

	The federal government, founding the Mississippi River Commission in 1879, created a seven-member group of engineers interested in navigational improvement and flood control. A four-and-one-half-foot channel project was begun in 1878. The depth of the channel was to be maintained by clearing the channel and constructing [[WING DAMS]]. Finding the depth of the channel insufficient, a second project was initiated in 1907 that called for a six-foot channel maintained by the construction of additional wing dams.

	As early as 1908 James J. Hill, railroad developer, predicted that Northwest and Midwest businessmen would need to rely on towboats and barges to move their commerce due to congested railways and high charges. He found that the average railway freight charge was 7.5 mills per ton while on the Great Lakes it was 1 mill and on the Ohio River 1/3 of a mill.		As early as 1908 James J.

	The Viking Mississippi was not the only vessel facing problems on the United States' premier river. With drought conditions, low water levels along the Mississippi forced several barges to run aground. The National Oceanic and Atmospheric Administration maintains a drought information website. Its most current report in early October, 2022 said almost 53% of the lower 48 states were in a drought. Drought and abnormal dryness "continue to develop and intensify from the Plains through the Mississippi River Basin, and have now extended further into the Midwest and Southeast. Low water levels are impacting barge traffic on the Mississippi River during the harvest, a crucial time," NOAA's site said.

	Among the findings were that more water was running through the river. Climate change causing heavier rainfall, more snow and higher temperatures along with land use practices and constructed restraints such as levees all played a role. In the lower portion of the upper basin--Iowa, Missouri, and Illinois--at least 50% of the river is constrained. The upper Midwest was projected to get wetter in the future with an increase in surfaces that were impervious which forced more water into the Mississippi River and its tributaries. Levees and floodwalls have cut off many wetland areas which would slow runoff. Rapid runoff from land led to more sediment and nutrients from the land running into the rivers. This killed native plants in the river and contributed to the Dead Zone, the low-oxygen region at the mouth of the Mississippi in the Gulf of Mexico. Any rebound in the growth of aquatic plants from the widespread loss in the 1980s would slow down water velocity and help sediment to settle. Flooding over longer periods of time threaten trees which die. When they are dead, invasive species of plants move in including reed canarygrass and Japanese hops.

A Viking river cruise ship heading north up the Mississippi River could not finish its voyage because of low water levels, according to a statement from the company on October 6th. "Unusually low water levels along the Mississippi River have caused sections of the river to be closed, impacting all northbound and southbound shipping traffic," the statement said. "The closures have caused delays that will prevent the Viking Mississippi from completing the sailing underway and from reaching St. Paul [Minnesota] for her next scheduled departure on October 15." The Viking Mississippi could hold up to 386 guests and was built in 2022, according to the company's website. Viking was advertising a 15-day trip in October from St. Paul to New Orleans starting at $12,999.		[[Image:viking1.png\|left\|thumb\|350px\|Sept. 6, 2022.
