00:00:00,000 --> 00:00:02,583
(upbeat music)

2
00:00:10,400 --> 00:00:11,800
- [Narrator] The history of the U.S. Army

3
00:00:11,800 --> 00:00:13,830
Corps of Engineers, Rock Island District

4
00:00:13,830 --> 00:00:17,100
is one that can be traced back to 1837,

5
00:00:17,100 --> 00:00:19,000
when a Lieutenant Robert E. Lee

6
00:00:19,000 --> 00:00:21,200
surveyed a portion of
the Mississippi river.

7
00:00:22,730 --> 00:00:24,900
That Lieutenant Lee, the same,

8
00:00:24,900 --> 00:00:27,730
who would later famously
become a Confederate General

9
00:00:27,730 --> 00:00:30,460
and Commander of the American
Confederate States Army

10
00:00:30,460 --> 00:00:32,710
during the American Civil War

11
00:00:32,710 --> 00:00:35,820
surveyed the Des Moines
Rapids above Keokuk, Iowa,

12
00:00:35,820 --> 00:00:37,140
and the Rock Island Rapids

13
00:00:37,140 --> 00:00:39,963
which ran from LeClaire Iowa
to Rock Island, Illinois.

14
00:00:41,140 --> 00:00:43,730
These two areas with the
most serious obstacles

15
00:00:43,730 --> 00:00:45,340
on the Mississippi river

16
00:00:45,340 --> 00:00:47,050
and virtually halted steamboat traffic

17
00:00:47,050 --> 00:00:48,473
during low river stages.

18
00:00:49,750 --> 00:00:52,960
Lieutenant Lee proposed
improvements on these two stretches

19
00:00:52,960 --> 00:00:55,400
by excavating rock to deepen the channel

20
00:00:55,400 --> 00:00:57,803
and work was authorized in 1852.

21
00:00:59,900 --> 00:01:03,070
In 1866, after the civil war ended,

22
00:01:03,070 --> 00:01:04,320
Congress authorized the Corps

23
00:01:04,320 --> 00:01:06,160
to plan and construct a lateral canal

24
00:01:06,160 --> 00:01:08,130
known as the Des Moines Rapids Canal

25
00:01:08,130 --> 00:01:11,800
along the Iowa side of the
river to bypass the rapids.

26
00:01:11,800 --> 00:01:14,420
The new canal was 7.6 miles long,

27
00:01:14,420 --> 00:01:17,620
five feet deep at low
water and had three locks.

28
00:01:17,620 --> 00:01:19,540
The canal cost more than $4 million

29
00:01:19,540 --> 00:01:22,280
and marked the official birth
of the Rock Island District.

30
00:01:22,280 --> 00:01:24,430
On August 3rd, 1866

31
00:01:24,430 --> 00:01:27,350
under the guidance of
Lieutenant Colonel GH Wilson,

32
00:01:27,350 --> 00:01:30,460
the Rock Island District
office opened in Keokuk, Iowa,

33
00:01:30,460 --> 00:01:33,090
to supervise construction of
the Des Moines Rapids Canal,

34
00:01:33,090 --> 00:01:35,863
which eventually opened
to traffic in 1877.

35
00:01:37,640 --> 00:01:40,590
In 1869, the Rock Island District office

36
00:01:40,590 --> 00:01:42,420
was moved to Davenport, Iowa

37
00:01:42,420 --> 00:01:45,720
to oversee work on removing
the Rock Island rapids.

38
00:01:45,720 --> 00:01:48,750
In 1870, the Rock Island
District headquarters

39
00:01:48,750 --> 00:01:49,660
was moved once again

40
00:01:49,660 --> 00:01:51,773
from Davenport to Rock Island, Illinois.

41
00:01:52,640 --> 00:01:55,100
As the district then stretched
from St. Paul, Minnesota

42
00:01:55,100 --> 00:01:56,710
to St. Louis Missouri,

43
00:01:56,710 --> 00:01:59,713
Rock Island was considered
the ideal geographic location.

44
00:02:00,550 --> 00:02:04,010
From the late 1870s to the early 1900s,

45
00:02:04,010 --> 00:02:06,510
Congress authorized several
comprehensive projects

46
00:02:06,510 --> 00:02:09,460
on the Mississippi river to
accommodate commercial traffic.

47
00:02:10,520 --> 00:02:13,260
The first project created a
four and a half foot channel

48
00:02:13,260 --> 00:02:16,550
by using a variety of
techniques, including dredging,

49
00:02:16,550 --> 00:02:20,450
constructing rock and brush
wing dams along the shore,

50
00:02:20,450 --> 00:02:22,040
and building closing dams,

51
00:02:22,040 --> 00:02:24,820
which closed off slews
and secondary channels

52
00:02:24,820 --> 00:02:26,720
to divert more water into the channel.

53
00:02:27,590 --> 00:02:31,990
In 1907, a six foot channel
was authorized by Congress

54
00:02:31,990 --> 00:02:34,323
as commercial vessels
were increasing in size.

55
00:02:36,260 --> 00:02:39,470
By 1925, despite improvements to the river

56
00:02:39,470 --> 00:02:41,023
commercial navigation declined,

57
00:02:41,950 --> 00:02:43,280
vessels larger than pleasure boats

58
00:02:43,280 --> 00:02:44,903
had become almost a curiosity.

59
00:02:45,840 --> 00:02:47,580
Other modes of transportation,

60
00:02:47,580 --> 00:02:50,210
such as the railroad were taking over.

61
00:02:50,210 --> 00:02:53,500
But new advancements in engineering
knowledge and techniques

62
00:02:53,500 --> 00:02:56,670
brought about the rebirth
of water transportation.

63
00:02:56,670 --> 00:02:58,610
New ideas on lock and dam construction

64
00:02:58,610 --> 00:03:00,900
were being tested and proven.

65
00:03:00,900 --> 00:03:02,040
Another important aspect

66
00:03:02,040 --> 00:03:04,710
was the development of
diesel powered river vessels

67
00:03:04,710 --> 00:03:07,210
that greatly increased
power and efficiency,

68
00:03:07,210 --> 00:03:09,170
capable of pushing a dozen or more

69
00:03:09,170 --> 00:03:10,733
heavily laden steel bargains.

70
00:03:12,670 --> 00:03:15,670
In 1930, convinced that
the economy of the Midwest

71
00:03:15,670 --> 00:03:17,210
would improve by a deeper channel

72
00:03:17,210 --> 00:03:19,800
that would accommodate these larger tows.

73
00:03:19,800 --> 00:03:22,843
Congress authorized the
nine foot navigation channel

74
00:03:22,843 --> 00:03:24,790
from the mouth of the Missouri river

75
00:03:24,790 --> 00:03:26,323
to Minneapolis, Minnesota.

76
00:03:28,290 --> 00:03:31,680
This was done by means of
creating a staircase of sorts

77
00:03:31,680 --> 00:03:33,590
using 28 lots and dams

78
00:03:33,590 --> 00:03:36,080
between the Missouri river and Minneapolis

79
00:03:36,080 --> 00:03:38,930
with 12 of these locks built
by the Rock Island District.

80
00:03:42,220 --> 00:03:46,550
In the 1930s and 1940s
construction of the locks and dam

81
00:03:46,550 --> 00:03:49,590
engaged almost all of
the district's efforts.

82
00:03:49,590 --> 00:03:52,180
The first of the series
was locks and dam 15

83
00:03:52,180 --> 00:03:55,613
at Rock Island, Illinois,
which was completed in 1932.

84
00:03:56,570 --> 00:03:58,560
The final piece came in 1940

85
00:03:58,560 --> 00:04:01,943
with the completion of lock
and dam 14 near LeClaire, Iowa.

86
00:04:04,600 --> 00:04:09,100
In 1932 during the busy lock
and dam construction period,

87
00:04:09,100 --> 00:04:10,620
the historic clock tower building

88
00:04:10,620 --> 00:04:14,480
located on Rock Island Arsenal,
adjacent to locks and dam 15

89
00:04:14,480 --> 00:04:16,330
became the district's permanent home.

90
00:04:18,380 --> 00:04:19,910
Also during this time,

91
00:04:19,910 --> 00:04:23,120
the St. Louis and St. Paul
Districts were established,

92
00:04:23,120 --> 00:04:25,180
which reduced the boundaries
of the Rock Island District

93
00:04:25,180 --> 00:04:28,030
to the portion between the
Wisconsin and Illinois rivers.

94
00:04:29,330 --> 00:04:32,920
In 1936, the Rock Island
District was further reduced

95
00:04:32,920 --> 00:04:35,510
to its present day,
North, South boundaries

96
00:04:35,510 --> 00:04:37,777
of Gutenberg Iowa in the North

97
00:04:37,777 --> 00:04:40,063
and Saverton Missouri in the South.

98
00:04:42,520 --> 00:04:46,860
In 1936, Congress made flood
control a federal concern

99
00:04:46,860 --> 00:04:48,230
and assigned the responsibility

100
00:04:48,230 --> 00:04:51,103
of carrying out its directives
to the Corps of engineers.

101
00:04:52,040 --> 00:04:54,710
Based on this new directive,
the Rock Island District

102
00:04:54,710 --> 00:04:57,380
had 14 individual flood control projects

103
00:04:57,380 --> 00:05:00,030
that were included in the
first round of legislation.

104
00:05:01,070 --> 00:05:05,730
From 1942 to 1945, at the
outbreak of World War II,

105
00:05:05,730 --> 00:05:08,070
the Rock Island District
shifted from civil works

106
00:05:08,070 --> 00:05:09,963
to military supply and procurement.

107
00:05:11,020 --> 00:05:14,350
It also designed and constructed
more than $80 million

108
00:05:14,350 --> 00:05:16,250
in military projects during this time.

109
00:05:18,350 --> 00:05:20,950
After World War II ended,
the district returned

110
00:05:20,950 --> 00:05:22,890
to civil works planning and construction,

111
00:05:22,890 --> 00:05:25,390
and began to refocus on
the flood control mission.

112
00:05:26,980 --> 00:05:28,670
That mission would result
in the construction

113
00:05:28,670 --> 00:05:31,370
of five reservoirs, with
the first project completed

114
00:05:31,370 --> 00:05:34,410
at Fon Du Lac Reservoir in 1949,

115
00:05:34,410 --> 00:05:37,033
followed by the Farmdale
Reservoir in 1951.

116
00:05:38,280 --> 00:05:39,550
Fon Du Lac and Farmdale

117
00:05:39,550 --> 00:05:41,630
are part of the Farm Creek
Flood Control Project

118
00:05:41,630 --> 00:05:43,023
in East Peoria, Illinois.

119
00:05:44,050 --> 00:05:46,760
Behind each dam, the Corps
of engineers owns the land

120
00:05:46,760 --> 00:05:48,690
that is subject to flooding.

121
00:05:48,690 --> 00:05:51,640
These areas will normally
be empty of standing water.

122
00:05:51,640 --> 00:05:54,320
Farm Creek and Fon Du Lac
Creek flow through a culvert

123
00:05:54,320 --> 00:05:55,583
in the respect of dams.

124
00:05:56,420 --> 00:05:57,330
When the flow in the creek

125
00:05:57,330 --> 00:05:59,400
exceeds the capacity of the culvert

126
00:05:59,400 --> 00:06:02,570
water starts to back up
into the reservoir area.

127
00:06:02,570 --> 00:06:04,800
The stored water is then
released at a slow rate

128
00:06:04,800 --> 00:06:06,850
through the outlet culvert.

129
00:06:06,850 --> 00:06:08,910
One advantage of the dry reservoir concept

130
00:06:08,910 --> 00:06:10,830
is there are no moving parts.

131
00:06:10,830 --> 00:06:13,330
The water is held back
and released automatically

132
00:06:13,330 --> 00:06:15,823
without the need to open or close gates.

133
00:06:16,910 --> 00:06:19,070
Continuing with the flood control mission,

134
00:06:19,070 --> 00:06:20,080
the Rock Island District

135
00:06:20,080 --> 00:06:22,150
completed three more reservoir projects

136
00:06:22,150 --> 00:06:23,200
in the state of Iowa.

137
00:06:24,400 --> 00:06:28,143
One at Coralville Lake
in Iowa City in 1958.

138
00:06:29,120 --> 00:06:33,423
Another at Lake Red Rock
in Pella, Iowa in 1969.

139
00:06:34,420 --> 00:06:38,613
And finally Saylorville Lake
in Johnston, Iowa in 1977.

140
00:06:40,870 --> 00:06:44,090
All three lake projects are
multiple purpose projects

141
00:06:44,090 --> 00:06:46,720
providing primary
benefits and flood control

142
00:06:46,720 --> 00:06:48,860
and low flow augmentation

143
00:06:48,860 --> 00:06:51,530
with secondary benefits in recreation,

144
00:06:51,530 --> 00:06:54,773
natural resource management
and environmental stewardship.

145
00:06:55,960 --> 00:06:58,940
Since being built the three links combined

146
00:06:58,940 --> 00:07:00,910
have prevented cumulative flooding damages

147
00:07:00,910 --> 00:07:04,363
of over $2.5 billion in
the downstream areas.

148
00:07:06,450 --> 00:07:09,310
In 1980, as a result of a core wide

149
00:07:09,310 --> 00:07:11,360
district realignment study,

150
00:07:11,360 --> 00:07:14,800
all river related responsibilities
of the Chicago District

151
00:07:14,800 --> 00:07:17,173
were transferred to the
Rock Island District.

152
00:07:18,020 --> 00:07:19,683
This change brought six rivers,

153
00:07:20,540 --> 00:07:25,540
the Illinois, Chicago,
Fox, Des Plaines, Kankakee,

154
00:07:26,450 --> 00:07:29,660
and Sangamon as well
as eight lots and dams

155
00:07:29,660 --> 00:07:32,423
on the Illinois waterway to
the Rock Island District.

156
00:07:33,880 --> 00:07:36,460
Years later in 2020,

157
00:07:36,460 --> 00:07:38,750
another realignment
will transfer operations

158
00:07:38,750 --> 00:07:42,210
of the TG O'Brien and
Lockport Locks and Dams

159
00:07:42,210 --> 00:07:43,660
back to the Chicago District.

160
00:07:44,570 --> 00:07:46,960
River navigation is an integral facet

161
00:07:46,960 --> 00:07:48,483
to commercial transportation.

162
00:07:49,420 --> 00:07:50,540
The Rock Island District

163
00:07:50,540 --> 00:07:53,580
has been proud to help
facilitate the navigation,

164
00:07:53,580 --> 00:07:55,193
which drives the global economy.

165
00:07:56,140 --> 00:07:59,390
But rivers are more than
just transportation systems.

166
00:07:59,390 --> 00:08:01,170
The Mississippi river watershed

167
00:08:01,170 --> 00:08:03,240
is the third largest in the world,

168
00:08:03,240 --> 00:08:05,603
and is an environmental
treasure like no other.

169
00:08:06,970 --> 00:08:09,470
Congress recognized the
Mississippi river system

170
00:08:09,470 --> 00:08:12,000
as a nationally significant ecosystem

171
00:08:12,000 --> 00:08:15,523
with the passing of the 1986
Water Resource Development Act.

172
00:08:16,603 --> 00:08:18,310
WRDA of 1986,

173
00:08:18,310 --> 00:08:21,250
established the environmental
management program,

174
00:08:21,250 --> 00:08:22,350
which is known today

175
00:08:22,350 --> 00:08:26,403
as the Upper Mississippi River
Restoration Program or UMRR.

176
00:08:28,340 --> 00:08:29,680
The Rock Island District

177
00:08:29,680 --> 00:08:32,970
has been proud to lead
that program for 30 years,

178
00:08:32,970 --> 00:08:35,270
completing nearly 60 projects

179
00:08:35,270 --> 00:08:38,123
and restoring nearly
110,000 acres of habitat.

180
00:08:39,750 --> 00:08:41,250
The program is world renowned

181
00:08:41,250 --> 00:08:43,650
for its commitment to
environmental restoration.

182
00:08:45,200 --> 00:08:47,380
Preserving and protecting the environment

183
00:08:47,380 --> 00:08:50,280
is imperative to the Rock Island District.

184
00:08:50,280 --> 00:08:53,900
But we are also dedicated to
protecting people and property

185
00:08:53,900 --> 00:08:56,083
from the unpredictability
of mother nature.

186
00:08:57,790 --> 00:08:59,550
Our emergency management mission

187
00:08:59,550 --> 00:09:02,380
has that us respond to catastrophic events

188
00:09:02,380 --> 00:09:04,603
like the Great Flood of 1993,

189
00:09:05,750 --> 00:09:08,673
hurricanes Katrina and Rita in 2005,

190
00:09:09,780 --> 00:09:13,090
record breaking flooding on
the Des Moines, Rock, Illinois

191
00:09:13,090 --> 00:09:17,780
and Mississippi rivers in
2008, hurricane Sandy in 2013,

192
00:09:18,830 --> 00:09:20,420
as well as more record-breaking flooding

193
00:09:20,420 --> 00:09:22,670
on the Illinois river in the same year,

194
00:09:22,670 --> 00:09:25,410
and most recently the
record breaking flooding

195
00:09:25,410 --> 00:09:27,623
on the Mississippi river in 2009.

196
00:09:29,120 --> 00:09:30,550
Throughout all of these events,

197
00:09:30,550 --> 00:09:33,280
the Rock Island District was
prepared to help communities

198
00:09:33,280 --> 00:09:36,223
with technical expertise
and flood fight material.

199
00:09:37,470 --> 00:09:40,670
In 2006, the district became recognized

200
00:09:40,670 --> 00:09:42,790
as a regional flood fighting center.

201
00:09:42,790 --> 00:09:45,480
And in 2014, it was designated

202
00:09:45,480 --> 00:09:47,960
as the national flood
fight material center

203
00:09:47,960 --> 00:09:51,950
with the ability to provide
sandbags, polyethylene sheeting,

204
00:09:51,950 --> 00:09:55,710
flood pumps, flood fight
products, and technical support

205
00:09:55,710 --> 00:09:58,610
to districts throughout the
continental United States.

206
00:09:58,610 --> 00:10:00,840
The Rock Island District
has had a rich history

207
00:10:00,840 --> 00:10:02,380
of providing value to the nation

208
00:10:02,380 --> 00:10:05,190
through a variety of engineering services.

209
00:10:05,190 --> 00:10:08,330
As we look to the future, our
people are prepared to adapt

210
00:10:08,330 --> 00:10:11,260
to an ever changing landscape
and take on each mission

211
00:10:11,260 --> 00:10:14,910
with the utmost professionalism,
expertise and ingenuity.
