Exploring the Upper Mississippi River<\/h2>\n

The Upper Mississippi River is a culturally significant area for many reasons. It is a vital thoroughfare for both leisure and commercial uses and serves as a primary source of drinking water, home to many endangered species, and a vital component of some of the largest wetland complexes in North America. Because of its size and significance, this great river has seen numerous explorers and adventurers pass through its depth over the years.
\nMost notably, the Upper Mississippi River’s exploration heavily began with the expedition of French Canadian traders Louis Jolliet and Jacques Marquette and voyageur-courier, Sieur de La Salle, in 1673. Jolliet and Marquette were sent out by the Governor of New France to explore the area, and although they hatched several plans and engaged in numerous trade negotiations with the many Native American tribes during their time in the region, their biggest accomplishment is generally lauded as the mapping of the Upper Mississippi.
\nFollowing this, other explorers of note that traveled and documented the region include the Jesuit Father Louis Hennepin, who documented many locations that the river travels through in the late 17th century, as well as Robert Cavalier, Sieur de La Salle, and France’s Antoine de LaMothe Cadillac in the early part of the 18th century.
\nIt wasn’t until 1804 that the United States would send an official expedition, headed by Meriwether Lewis and William Clark, to survey the region. Their famous ‘Corps of Discovery’ mission was, at the very least, successful in documenting the river basin and contributing to the more than 500 page journal that was compiled afterwards with detailed handwritten accounts of their voyage. <\/p>\n

Military Expedition along the Upper Mississippi<\/h2>\n

In the mid-19th century military expeditions began to be conducted along the Upper Mississippi by both the United States and Britain. This period marked the start of the tug-of-war between the two powerhouses for control of the area and as a result, soldiers were dispatched in order to collect intelligence. One of the most important reasons for these expeditions was that it increased the knowledge of the area, especially for the several forts which were built along the Mississippi to protect upstream commerce from Indian attack.
\nDuring this period, the United States Army additionally aided the movement of steamboat traffic through the region by removing obstacles and building canals, locks and dams to make navigation along the length of the river easier. They also enacted legislation to protect navigable streams. <\/p>\n

Enduring Explorations<\/h2>\n

In the late 19th and early 20th centuries, military and civilian explorers continued to survey the river with little interruption – the primary goal being to maximize the amount of usable water in the Mississippi River Basin and to protect the area’s resources.
\nBeginning in 1915, army engineer and public health official Hugh L. Cooper led a two-year mission that sought to better understand water pollution in the Upper Mississippi. His three-member team surveyed the area in multiple phases and identified over one thousand issues impacting water quality. It is his work that is largely responsible for modern environment protection initiatives.
\nSimilarly, the Corps of Engineers’ 1925-1930 Waterways Experiment Station led by Elmo Yancy sought to better understand the hydrology of the waterway, collecting samples from the entire river to study its sediment transport, navigation potential and water quality. This mission produced invaluable for constructing navigation projects and maximizing the river’s potential for recreation. <\/p>\n

Investigations by the Army Corps of Engineers<\/h2>\n

The Army Corps of Engineers conducted numerous investigations to improve the navigation of the river over the course of several decades. Between 1947 and 1989, their Navigation Data Center (NDC) collected thousands of records on hydrology, navigation and operations on the Mississippi. While they mostly investigated the lower reaches of the Mississippi, the NDC surveying team did investigate many significant reaches of the Upper Mississippi.
\nThe NDC’s work was followed by the Navigation Systems Support Center which aimed to compile the vast amount of navigational data collected over the decades. Their surveys revealed many difficulties posed by the river for navigation purposes, such as shoals and high siltation rates in many areas. <\/p>\n
