Fish Community Assembly in the Missouri River Basin
Warmwater fish communities of the Missouri River basin are poorly studied. I conducted a series of investigations intended to explain fish community structure and composition therein. I focused on relations between environmental characteristics and fish species because abiotic factors are …

Upper Missouri River Basin Aquatic GAP Fish Distribution Model Accuracy Assessment and White Sucker, Catostomus commersonii, Population Characteristics in the Upper Missouri River Basin
… at 61 sites in 6 drainages throughout the upper Missouri River Basin. A total of 21,204 fish were collected, representing 42 species and 11 families. Minnows (family Cyprinidae) dominated the catch (77.9%), followed by suckers (family Catostomidae, 6.5%), and catfishes (Ictaluridae, 5.7%). Of the …

Groundwater flow in part of the Little Missouri River Basin, North Dakota
<p> The Little Missouri valley in western North Dakota is deeply incised into slightly permeable Mesozoic and Cenozoic sediments. An evaluation of the groundwater flow in part of this valley was 'based on the present groundwater flow-system models. Abrupt changes in the hydrochemical facies have …

Population Status and Characteristics of Macrhybopsis Gelida, Platygobio gracilis and Rhinichthys cataractae in the Missouri River Basin
… gelida were collected at 28 sites on the Powder River (n = 158) in Wyoming and Montana, and at one site on the Yellowstone River (n = 1) in Montana. Age-I, Age-II and Age-III M. gelida were collected. Specimens were 37 to 95 mm in total length. Macrhvbopsis gelida were ripe in mid-June, at water …

Correlation between the precipitation and energy production at hydropower plants to mitigate flooding in the Missouri River Basin
… be split into three main classifications: run of river, basins, and reservoirs. The energy production at hydropower plants can vary on a monthly basis, and this change is recorded for company purposes. This study used data provided for five reservoir plants in the Missouri River Basin to model …

The Ebb and flow of policy, economics, and science: an analysis of policy drivers in the Missouri River Basin
The Missouri River basin underwent a major transformation when the United States Congress approved the Flood Control Act of 1944 and the Bank Stabilization and Navigation Project of 1945. Generations removed from those national policy decisions, the long-term effects are now quantifiable. The …

Macroinvertebrate Biomonitoring Criteria and Community Composition in Seasonal Floodplain Wetlands of the Upper Missouri River
Regulated river flows and land-use activities have altered the floodplain ecosystem within the Upper Missouri River basin. These changes have led to decreased connectivity between the floodplain and main river and enhanced land-use activities (i.e., agriculture) within the floodplain. Knowledge of …

EVALUATING EMBRYO SURVIVAL OF SURROGATE FISH SPECIES USING MULTIPLE INCUBATORS: CONTINUING EFFORTS TOWARDS REINTRODUCING ARCTIC GRAYLING (THYMALLUS ARCTICUS) INTO LOWER MICHIGAN STREAMS
… have been successfully reintroduced to the Upper Missouri River Basin of Montana using Remote Site Incubators (RSI). Widespread use of RSIs as part of reintroduction efforts in Michigan is challenged by low gradient streams, which limit deployment success. In this study, I evaluated the utility of …

An Architectural Analysis of Caddo Structures at the Ferguson Site (3HE63)
… The Ferguson site (3HE63), located in the Little Missouri River basin of Southwest Arkansas, contains architectural remains in Middle Caddo contexts. Many of the structures excavated from within the large platform Mound A and the smaller conical Mound B were burned and buried, resulting in a …
