As is the case with the Columbia River, the Missouri River has been tamed by a series of dams  and other structures so that the original river has almost completely disappeared in terms of an ecosystem with a diverse community of river invertebrates.

A very good introduction is provied by Northern State University in South Dakota; includeing pre-glacial drainage.


The following quote is from the above link: "The Missouri River of today, now "tamed," is very different from the river prior to human influence. Today, the river is divided into approximately three equal parts: the lower one-third, below Sioux City, Iowa is channelized ; one-third is impounded by six large dams; and one-third consists of remnant "free flowing" stretches of water. Only one percent of the river's entire length remains truly uncontrolled by humans  (emphasis mine}."

A number of other very useful and interesting sources are available in print and on line:

More information and background on management, the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers, and description of the river:

Dams that affect the Missouri in North Dakota



To focus on my objectives, and  to emphasize again from the quote at the top of this page: 

1.  Only one percent of the entire length of the Missouri remains truly uncontrolled by humans."

2.  Today, the river is divided into three equal parts:

      a.   the lower one-third, below Sioux City, Iowa is channelized.

      b.   the middle one-third is impounded by six large dams mostly in North and South Dakota, but one major dam in Montana.

      C.   the upper one-third, mostly Montana consists of remnant "free flowing" stretches of water.


The Questions

As for the Columbia River, the questions  here is about the original river invertebrate communities, and also the present condition of various parts of the river.:

Middle River, The Dakotas

     For the first topic,  I am interested in the mid region of the river for personal reasons.  It is a section of about 700 river miles, from west central North Dakota to southeastern South Dakota.  This section is now a series of lakes formed by several  dams.  The river floods that I remember as a child in central South Dakota no longer occur.  The situation is similar to that of  the Columbia River.  The Oahe Dam in South Dakota near Pierre backs water into North Dakota almost to Bismarck, and another dam north of Bismarck forms a lake that reaches to within a few miles of the Montana border.  More dams are found downstream from Pierre to the Nebraska border.

     The  river insects  and invertebrates that originally occurred are now gone from the main Missouri River channel  in this mid section.    I am not sure if detailed ecological studies were made before dam construction, but I am not aware of samples or data if they do in fact exist.

What was the original invertebrate benthic fauna of the middle, Dakota, sectionof the Missouri River?  What eviicence is available?


      A partial  answer may be that  a  number of significant tributaries enter the Missouri in this section, especially in western South Dakota..  The Little Missouri is a significant tributary in North Dakota, and in South Dakota, tributaries entering  the Missouri are the Grand, Moreau, Cheyenne, Bad, White, James, Vermillion, and Big Sioux Rivers, plus the Keya Paha, entering in Nebrasks.

     Recent scientific reports indicate that these tributaries have supported or now support  a number of characteristic river species of mayflies .  Again, these species apparently are gone from the main channel at the present time, but presumably historically occupied the main Missouri channel.

Mayflies from Missouri tributaries in South Dakota (Guenther and McCafferty 2008, Mayflies of South Dakota):

1.  Camelobaetidius warreni (Traver and Edmunds): Cheyenne River, Little Missouri River, also found in the Saskatchewan River.

2.  Pseudocloeon dardanum (McDunnough) Vermillion River, Cheyenne River, also found in the Saskatchewan River.

3.  Caenis latipennis Banks Little Missouri River, also in the Sask. Riv.

4.  Baetisca lacustris, Yankton, Missouri River, Vermillion River, also Sask. Riv.

5. Cercobrachys cree, Cheyenne Riv., also Sask. . Riv.

6.   Hexagenia bilineata, H. limbata, both at Yankton, Missouri River, the latter also Sask. Riv.

7.  Heptagenia elegantula, as H. diabasica,  Missouri Riv., Vermillion Riv., also Sask. Riv.

8.  Heptagenia flavescens (Walsh),  Vermillion, Missouri Riv., also Sask. Riv.

9.  Maccaffertium terminatum (Walsh), Vermillion, Grand Rivers,. also Sask. Riv.

10.  Isonychia bicolor (Walker), I. rufa, Grand River, Little Missouri, at Sioux Falls; A similar species, Isonychia campestris , is found in the Sask, Riv. 

11.  Leptophlebia nebulosa, Cheyenne River, also Sask. Riv.

12.  Ephoron album (Say), Grand River, Moreau Rivers, also Sask. Riv.

13.  Traverella albertana, Grand River, Standing Rock Res., also Sask Riv.

14.  Pseudiron centralis, Tripp Co., Keya Paha Riv., also Sask. Riv.

Although the above 14 species are shared by the Saskatchean River and Missouri River tributaries, especially in South Dakota, a general statement about the group of 14 is that they are mostly common and widespread.  Rare or uncommon species such as Raptohetagenia cruentata, Macdunnoa nipawinia, and Ametropus sp. are not present.

A further observation is that a several unusual species and Families are found in South Dakota but not  in the Saskatchewan River system:

1.  Palingeniidae - Pentagenia vittigera (Walsh), Yankton, Missouri River.

2.  Leptophlebiidae- Neochoroterpes oklahoma,  Cheyenne River, Little Missouri (Choroterpes albiannulata is found in the Sask. River).

3.  Potamanthidae - Anthopotamus myops (Walsh), Vermillion River, Big Sioux River, Brookings (James Riv.?).

4. Oligoneuriidae - Homoeoneuria alleni, Keya Paha, Big Sioux, "common to the Missouri River drainage" (Guenther and McCafferty)


Under Construction

The Upper River, Montana Mayflies

In general these records are from the upper, undamed areas of the Missouri, or from the Yellowstone drainage, which flows into the Missouri at the North Dakota border.    Thus, the species below were almost certainly historically found in the Middle, now flooded, sections of the Missouri in the Dakotas.   Notice that many rare and unusual mayflies below, e.g. Raptoheptagenia, Macdunnoa, Lachlania, are not found in the Dakota tributaries, but are shared with Saskatchewan.
