2. Scenic Missouri River
The
Missouri River and its people have captured our nations attention
since the time of Lewis and Clark. Artists such as Carl Bodmer,
George Catlin, James J. Audubon, Carl Wimar, and Phillipe R. de
Trobriand have depicted the Missouri, the landscape, and the people
who reside on its banks. Channeled, dammed, diverted for industrial
and municipal use, the river has changed, but the portion of the
river from Garrison Dam to Lake Oahe still echoes the river that
Lewis and Clark traveled in 1804 - 1806.

3. Native Peoples and the River I
Peoples,
known as the Plains Village Tradition, have lived along the Missouri
for about 1000 years. Mandan, Hidatsa, and Arikara peoples lived
in villages along the Missouri from the South Dakota to the Montana
border. When Lewis and Clark spent the winter of 1804-1805 near
modern day Stanton, there were more Mandan and Hidatsa peoples living
in the nearby five villages than the entire population of St. Louis.
The Knife River confluence area was the center of a vast trade network
that moved Knife River flint from North Dakota, shell from the Gulf
of Mexico, copper from the Great Lakes, and corn from the Missouri
River villages throughout the plains. French and British traders
traveled by canoe and horse to trade and interact with this network.
The Missouri River was a source of water, and the annual floods
would deposit rich nutrients and silt on the bottom-lands. Crops
of corn, beans, squash, sunflowers, and tobacco were raised along
the river. The Missouri sustained bushes and shrubs laden with berries,
medicinal plants and herbs. The river provided fish and supported
wildlife. Stands of cottonwood, that thrived on the banks of the
river, provided the timber necessary to build the earth-lodge villages
and fuel for cooking and heating.

4. Native Peoples and the River II
Native
people used bullboats made of bison hide stretched over a wood frame.
American explorers and traders used keel boats supplied with oars,
poles, and sail, capable of carrying 15 to 30 tons of cargo. They
would travel up the river with trade goods and down with furs. Lewis
and Clarks keel boat was 55 feet long, 8 feet wide, and had
a mast 32 feet tall. Keel boats were used primarily from 1800 to
1840, when they were replaced by steamboats. Mackinaw boats had
a flat bottom, pointed stem and square stern and could carry 25
tons of cargo. Built for one-way trips, down river, to St. Louis,
where they were broken up for lumber.

5. Steamboats - Navigation I
In
1832 the steamboat Yellowstone traversed its way up the Missouri,
ushering in a new era, and allowing the rapid transport of goods
from St. Louis to Fort Union and beyond. Independent contractors
known as wood-hawks would cut, haul, and pile timber on the river
banks, for the steamboats to use as fuel. Steamboats used on the
Missouri had a shallow draft, powerful engines, and a stern wheel.
Two annual periods of high water allowed easy navigation up the
river to Fort Benton, Montana. The April rise was the result of
local snow melt, while the June rise was the result of snow melt
in the Rockies. In 1876, the Far West, riding the June rise,
brought the wounded members of the 7th Cavalry, U.S. Army, back
from the Battle of the Little Bighorn, setting a speed record on
the Missouri.
During the winter months, from November to March, the boats would
be hauled onto quays in ice harbors by the side of the river to
allow repairs, and prevent them from being crushed by ice floes
in the spring. The Bismarck ice harbor moved several times, before
being moved to Rock Haven. As railroads reached the region, the
main port for steamboats shifted from Yankton to Bismarck.

6. Steamboats - Navigation II
The
US Army Corps of Engineers had the responsibility to keep the river
free of snags and other obstructions. As the river shifted, trees
on the banks would collapse into the river and become snags or sawyers.
Snags could disable or sink a passing vessel. If necessary, channels
were dredged to allow steamboats to pass beneath or by railroad
bridges. The Northern Pacific Railroad bridge at Bismarck , completed
in 1883, was built 50 feet above the water, allowing steamboats
to pass beneath.

8. Crossing the River - Fording I
With
constantly shifting channels, quicksand, and sandbars, the Missouri
presented enormous challenges for those who needed to cross it.
In winter, the frozen river provided a natural bridge people, animals,
and machines to cross. The spring melt and break up of the ice created
dangers that would result in the drowning of people and animals
as they sought to cross the river.
we found a number of carcases of the Buffaloe lying along shore,
which had been drowned by falling through the ice in winter and
lodged on shore by the high water when the river broke up about
the first of this month. Diary of Meriwether Lewis, April 13,
1805 (2)

10. Bridging the River I
The
first bridge across the Missouri was the Northern Pacific bridge
at Bismarck. Soaring 50 feet above the high water level of the river,
the base of the piers rest 50-60 feet below the river. From September
1881 to June 1882 workers used pneumatic caissons (watertight, under-water
construction structures) to sink the middle piers to bedrock, risking
caissons disease, or the bends.
The creation of a national highway system in the 1920s resulted
in bridges for automobiles across the Missouri. The Liberty Memorial
bridge at Bismarck was completed in 1926, and was the first automobile
bridge across the Missouri in North Dakota. The Verendrye bridge
at Sanish was completed in 1927, and the Lewis and Clark bridge
at Williston in 1927. (3) Railroads and highways, built on east
to west routes, altered the north to south trade routes that had
been established for centuries. The Missouri was no longer a principal
means of moving man and goods.

12. Flooding I
Flooding
on the Missouri River endangered not only transportation, but communication,
lives, and property. In a series of floods between 1884 and 1950,
homes and businesses were placed at jeopardy, and transportation
links were nearly severed.
The low-lying land adjacent to the river, known as the bottoms,
was frequently flooded. Seeds of cottonwood trees were spread by
flood waters and nourished by the rich silt deposits. Groves of
cottonwood provided habitant to numerous birds and animals.

trees. Diary of John Ordway, April 10, 1805 (4)

14. Controling the River
The
U.S. Army Corps of Engineers built rock stabilizing walls known
as revetments, to consolidate the shoreline and channel the river
for navigation.

15. Garrison Dam I
Continual
flooding of the Missouri River forced people into action. The creation
of revetments to stabilize the shoreline and help to channel sections
of the river were one of the creations of the U.S. Army Corps of
Engineers. The permanent creation of Garrison Dam marked the end
of the April and June rises, the perennial flooding of the Missouri.
But the dam came at a cost, thousands of acres were inundated and
native peoples up-rooted. Flood control, power generation and water
for agricultural irrigation, municipal use, and industrial use are
some of the benefits of the Garrison project. Municipal water systems,
such as the Southwest Pipeline project are tapping into the Missouris
water.
The Garrison Dam was constructed from 1947 to 1954 at a cost of
$300 million. It is 210 feet high and 2.5 miles long. The five generating
units produce 2,600,000 megawatts of electricity, enough to supply
the annual power needs of 350,000 people. The towns of Riverdale
and Pick City were created to house the construction workers and
their families.

16. Garrison Dam II
In
1954 the waters of the Missouri River, held back by the new Garrison
Dam, began to fill the valley and cover several communities, including
the site of Like-a-Fishhook Village. The dam was to flood 156,000
acres of the Fort Berthold Reservation, all of it wooded bottomland
and bench lands where 90% of the tribal population lived.
You will excuse me if, first, I say that we will sign this contract
with a heavy heart. With a few scratches of the pen, we will sell
the best part of our reservation. Right now the future does not
look too good to us. (5) George Gillette, Chair of the Fort
Berthold Tribal Council, May 20, 1948.

Reservation. New Town celebrated her Golden Jubilee in 2001.
Garrison Dam. The reservoir behind the dam, initially slated to
be dubbed Lake Thompson, was named Lake Sakakawea, in honor of the
Sakakawea, the Hidatsa woman who accompanied the Lewis and Clark
expedition of 1804 to 1806 * A7120
17. Agriculture I
Native
peoples used the bottom lands of the Missouri River for gardens
after the river had deposited its yearly nourishment of silt. Corn,
beans, squash, and pumpkins grown by native peoples supplemented
the diet of the men of the Lewis and Clark expedition. Native peoples
seeds formed the basis for new plant varieties introduced by the
Oscar Will Seed Company to farmers of the region.
Irrigation has long been a vision for agriculture along the Missouri.
A variety of pumps and ditches have been used to bring water to
land adjacent to the river. The Garrison Diversion Project was part
of the vision of the Garrison Dam, to irrigate the farmlands of
central North Dakota.
Mandan people, well known for their gardens along the river by the
time Lewis and Clark visited Crow Chiefs village in 1804.

is carrying a basket typically used to transport corn and other
garden produce.

19. Economic Activities I
The
harvesting of ice was an economic activity necessary prior to the
advent of refrigeration. Ice was cut from the river and hauled to
insulated storehouses, where it would last into the late summer.
The trees along the Missouri provided building materials for native
peoples, traders, and early American settlers. Sawmills eventually
replaced the earlier wood hawks who supplied the timber necessary
to power the steamboats.
The BP Amoco refinery at Mandan uses 516 million gallons of water
per year in the refinery process, to make steam and cool equipment.
Eight coal-fired generating plants draw water from the Missouri
River or Lake Sakakawea. Each year 159.5 billion gallons (6) of
water is drawn from and returned to the Missouri and 10.2 billion
gallons of water is drawn and consumed in the production of electricity.(7)
Electricity produced by Garrison Dam and the eight coal-fired generating
stations is carried on high power transmission lines to eastern
customers.

20. Economic Activities II
The
Missouri provides water to the nine power generating plants in North
Dakota as well as the BP Amoco refinery at Mandan. Built in 1954
by Standard Oil Company, it is near Rock Haven, the old ice harbor
for steamboats and gasoline packet boats on the banks of the river.
The BP Amoco refinery draws in 803 million gallons per year and
it is used to help refine 21.5 million barrels of oil per day. The
refinery cleans, treats, and returns to the Missouri, 277 million
gallons per year.(8)

21. Recreation I
The
Missouri River became a source of recreation after World War II.
The wood hulled power boats have given way to aluminum and fiberglass
boats as recreation on the river and reservoir have increased. Lake
Sakakawea, created behind the Garrison Dam in 1954 is 178 miles
long, with 1,530 miles of shoreline and covers 382,000 acres. It
is the third largest man-made lake in the United States and contains
32 percent of all the stored water in the Missouri River dam system.
The Missouri River, the route of the Lewis & Clark expedition
from 1804-1806, has become a tourism destination as Americans re-trace
the Corps of Discovery.
