Multi-Objective Water Management In Idaho's Henrys Fork Watershed: Leveraging Reservoir Operation And Groundwater Pathways To Benefit Aquatic Habitat, Christina N. Morrisett

All Graduate Theses and Dissertations, Fall 2023 to Present

Multi-user water management is a challenging arena further complicated by climate change. This research is based in the Henrys Fork, Snake River, Idaho—an agricultural watershed that exemplifies those throughout the semi-arid American West. This dissertation uses an integrated approach that considers groundwater-river relationships, farm-scale decisions and basin-scale outcomes, upstream reservoir operation for downstream aquatic habitat, water rights, and collaborative stakeholder management to identify drought adaptation strategies accordingly.

Chapter 2 uses an interdisciplinary approach to quantify how improvements to irrigation efficiency at the farm-scale (i.e., converting from flood to sprinkler irrigation) can add up to affect hydrology at the landscape-scale and …

Gibberellic And Naphthalene Acetic Acid Effects On ‘Rupert’ Potato Variety, Logan Atkinson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Potato processing facilities often rely on early maturing potato varieties to maintain adequate supplies before harvest of more traditional varieties. The Rupert variety is an example of such an early-maturing variety. However, the Rupert variety has traditionally been characterized by low average stem counts and large tuber sizes. Abnormally large tubers can add difficulties and costs to the processor. Gibberellic acid (GA) and Naphthalene acetic acid (NAA) are plant growth regulators that promote growth and have the potential to affect average stem count and in turn, decreases average tuber size. Across two trials and locations (Gooding and Jerome, ID) GA …

The Non-Fee Costs Of Grazing On Idaho State Grazing Leases, Dexton Lake

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

In 2018, Idaho became interested in assessing and raising the grazing fee for state grazing ground. The state commissioned a study to analyze the non-fee costs of grazing, but for various reasons the study was not completed. In 2021, a proposed adjustment was released by the Idaho Department of Lands to raise the fee. In a desire to obtain the non-fee costs of grazing for Idaho state leases and to get stakeholder input, the Idaho Farm Bureau Federation and a research team from Utah State University surveyed Idaho producers to obtain costs per AUM for eleven cost categories. These cost …

Debitage Attributes, Obsidian Source Analysis, And Prehistoric Mobility In Southeastern Idaho, Ben Joaquin Zumkeller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study is to complement existing knowledge on prehistoric mobility in eastern and southern Idaho. I add specific detail regarding the use of Skull Canyon and its well-known Birch Creek rockshelters during hunter-gatherers’ logistical foraging rounds.

In addition, my research is a case study in combining debitage attribute analysis and intensive toolstone sourcing to read prehistoric mobility. Prior research has looked to obsidian toolstone sourcing to understand prehistoric eastern and southern Idaho mobility. However, no prior research has involved sourcing an entire, stratified assemblage of prehistoric debitage.

I collected flake attribute data from all 2,846 pieces of …

Analysis Of Sat And Isat Scores For Madison School District In Rexburg, Idaho, Holly Dawn Palmer

Undergraduate Honors Capstone Projects

Testing is an integral part of measuring education. If used properly SAT scores can be compared across the nation, and statewide tests can compare different school districts to each other if done properly to avoid certain pitfalls (Fetler, 1991). However, if tests do not have a significant impact on a student, their motivation to take the test will be low and test quality cannot be assumed. When the state funds two separate tests for their students but only one has a significant impact on the student, how should the scores for each test be used, and is it okay to …

The Farm As Place In A Changing Climate: Capturing Women Farmers' Experiences In Idaho, United States And Victoria, Australia, Tagen Towsley Baker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In Australia and the US, women play a vital role in the agricultural sector. However, historically farmwomen’s contributions to agriculture as well as their individual knowledge and social resilience to stressors like climate and climate change have been unrecognized and rendered invisible. Drawing on interdisciplinary scholarship from geography and the humanities, this dissertation explores the farm as place in a changing climate, drawing on women farmers’ experiences, under three distinct themes: identity, place, and photography. The dissertation research includes three distinct parts. First, incorporating non-fiction writing and photography, I explore my agricultural and religious heritage, as well as familial connections …

Influence Of Environmental Variables On Survival Rates Of Pronghorn (Antilocapra Americana) Neonates Across Idaho, Brett R. Panting

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was completed to better understand pronghorn antelope (Antilocapra americana) populations found throughout Idaho. Antelope were studied in three separate and distinct study areas. The Big Desert, Camas Prairie, and Little Lost and Pahsimeroi valleys were all selected as study sites. Idaho Department of Fish and Game (IDFG) is concerned with current pronghorn populations found throughout Idaho. Pronghorn are a valued big game species found in Idaho. Increasing pronghorn populations in Idaho is a focus of IDFG.

We captured and VHF-collared pronghorn fawns found in our three study areas. Fawns were monitored daily with telemetry equipment for …

Groundwater And Surface Water Contributions To Metals Loading In Bayhorse Creek At The Abandoned Ramshorn Mine Site Near Bayhorse, Idaho, Hannah L. Mcdonough

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The U.S. Forest Service (USFS) and the Idaho Department of Environmental Quality (IDEQ) purchased property encompassing the abandoned Ramshorn mine to develop a state park. Because the abandoned copper-lead-silver mine was a potential hazard to the local creek and sediment, the IDEQ conducted several assessments to identify environmental risks. Between 2003 and 2006, the IDEQ completed a number of basic soil and water investigations in the location of mine waste. The IDEQ received investigation and cleanup funds through the EPA Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) program.

The USFS allocated $10,000 toward a two-year master’s level project to …

Site-Based And Nonsite Archaeological Survey: A Comparison Of Two Survey Methods In The City Of Rocks, Idaho, Patrick Reed Mcdonald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Archaeology in the western United States frequently employs pedestrian survey of the ground surface to locate and identify archaeological sites. Proponents of alternative survey techniques suggest that site-based survey may be inherently flawed and will not accurately detect, document, or account for artifacts located outside of site boundaries. Site-based survey identifies artifacts, and then searches the area more intensively in an attempt to identify a spatial break in artifact presence. Nonsite approaches utilize point plotting of all discovered artifacts in order to quantitatively identify relationships between artifacts. Quantitative analysis removes a level of researcher bias from the interpretation of past …

Factors Influencing The Ecology Of Greater Sage-Grouse Inhabiting The Bear Lake Plateau And Valley, Idaho And Utah, Casey J. Cardinal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Greater sage-grouse (Centrocercus urophasianus; sage-grouse) are a sagebrush obligate species and as such an indicator of sagebrush (Artemisia spp.) habitat quality and quantity. Sage-grouse populations have declined across western North America. This decline has been attributed to habitat loss and degradation of the sagebrush ecosystem. To determine factors that may cause localized declines in sage-grouse populations, managers may need site-specific information on the ecology and habitat use patterns of meta-populations. This information is currently lacking for sage-grouse populations that inhabit the Bear Lake Plateau and Valley (BLPV), encompassing parts of Idaho, Utah and Wyoming. I captured, radio-marked …

In Situ Stress And Geology From The Mh-2 Borehole, Mountain Home, Idaho: Implications For Geothermal Exploration From Fractures, Rock Properties, And Geomechanics, James Andrew Kessler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Geothermal energy is being explored as a supplement to traditional fossil fuel resources to meet growing energy demand and reduce carbon emissions. Geothermal energy plants harvest heat stored in the Earth’s subsurface by bringing high temperature fluids to the surface and generating steam to produce electricity. Development of geothermal resources is often inhibited by large upfront risk and expense. Successful mitigation of those costs and risks begins with efficient characterization of the resource before development. A typically successful geothermal reservoir consists of a fractured reservoir that conducts hydrothermal fluids and a cap rock seal to limit convective heat loss through …

The Kimama Core: A 6.4 Ma Record Of Volcanism, Sedimentation, And Magma Petrogenesis On The Axial Volcanic High, Snake River Plain, Id, Katherine Elizabeth Potter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Snake River Plain (SRP) is one of the best-preserved examples of continental hotspot volcanis, with a continuous record of volcanism that extends over 16 Ma to the present. Yellowstone-Snake River Plain records the migration of plume-tail volcanism from inception at the Bruneau-Jarbridge caldera complex at 12.6 Ma to its present locus, under the Yellowstone Plateau.

Records kept by the Snake River Plain volcanic actions include rhyolite lavas and ignimbritesm minor coeval basalts, and an overlying veneer of younger basalts. The central SRP has received comparatively little attention in the past. The Kimama core hole was drilled as part of …

The Baker Cave Bison Remains: Bison Diminution And Late Holocene Subsistence On The Snake River Plain, Southern Idaho, Ryan P. Breslawski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis investigates that paleoecology of southern Idaho bison and their role in prehistoric subsistence with two articles. The first article investigates the trajectory of bison diminution in southern Idaho with bison morphometrics from Baker Cave, a late Holocene archaeological site. Results indicate that local bison followed a diminution trend mirroring the diminution trend documented on the Great Plains. This suggests that similar bottom up ecosystem controls acted on bison in both the Great Plains and in southern Idaho through the Holocene.

The second article examines the role of bison in seasonal subsistence strategies. I hypothesize that winter fat scarcity …

Evaluation Of The Geothermal Potential Of The Snake River Plain, Idaho, Based On Three Exploration Holes, Thomas G. Freeman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The work in this thesis was based on analyzing water samples collected from three exploratory boreholes drilled during Project Hotspot. The water samples were analyzed for their chemical properties. The chemical properties of the water samples were used as a basis for further analysis.

Geophysical logs, mainly temperature logs, were also analyzed for this project. Temperature logs measure temperature in relation to depth within a borehole.

All the analyses were made in order to estimate the geothermal potential of the project areas. The exploratory boreholes were all drilled in different areas and each had unique characteristics. The Mountain Home borehole …

“Next Year In Jerusalem”: The Trials And Triumphs Of Music In The Schools Of Preston, Idaho, 1888-1995, Jill Durrant

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Throughout time, music has played a pivotal role in the lives of people. In every country, among every ethnicity, and as part of every culture, music has a presence. Music often acts as a mirror, reflecting aspects of society and history in ways that even the ordinary person can understand. No matter what the form—religious, popular, classical, folk—music has the ability to reveal something about the people who created it, performed it, and enjoyed it. Because of this overarching presence of music in the structure of almost every civilization, it is no surprise that music has always had some part …

Geothermal Alteration Of Basaltic Core From The Snake River Plain, Idaho, Christopher Joseph Sant

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Snake River Plain is located in the southern part of the state of Idaho. The eastern plain, which this study focuses on, is a trail of volcanics from the Yellowstone
hotspot. Three exploratory geothermal wells were drilled on the Snake River Plain. This project studies basaltic core from the first well at Kimama, north of Burley, Idaho. The objectives of this project are to establish zones of geothermal alteration and analyze the potential for geothermal power production near the center of the Snake River Plain. Thirty samples from 1,912 m of core were sampled and analyzed. Mineral data, temperature …

The Legend Of The Almo Massacre: Ostensive Action And The Commodification Of Folklore, Jonathan A. Floyd

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The following thesis is based on the role a legend plays in establishing and influencing a sense of identity and reality within a community and area, in this case the legend is of a massacre occurring in Almo, Idaho in the early 1860s. I found this legend of the Almo massacre while looking for an excuse to rock climb in the nearby City of Rocks National Reserve. I explored the Almo legend through interviews, historical documents and books and came to think that the Almo legend played a critical role in defining a sense of local reality for Almo, Idaho, …

The Pliocene/Pleistocene Evolution Of The Western Snake River Plain Near Grand View Idaho, Meagan R. Deraps

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Western Snake River Plain provides us with a unique opportunity to study the evolution of basaltic volcanism. In addition to studying the horizontal variation at the surface of the plain, erosion by the Snake River also allows the study of the vertical variation. With the aid of a USGS EDMAP grant we mapped the Dorsey Butte quadrangle and southern half of the Little Joe Butte quadrangle at a scale of 1 :24,000. The quadrangles are located within both the Ada and Elmore counties of southwestern Idaho, approximately 30 km west of Mountain Home and 2 km north of Grand …

Investigations Into Mapping Lava Flows In The Snake River Plain, Idaho, Vinita Ruth Hobson-Broko

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The origin of the Snake River plain continues to be debated, but the plume model is most popular at the current time. Some theories, such as meteorite impact, have been excluded, but the remaining theories require more scrutiny.

Various methods of examining phenomena in the Snake River Plain were employed. Unsupervised classification of Landsat ETM data indicates that spectra can be used to differentiate between flows. However, photographs of flows at Craters of the Moon National Monument show wide variations in texture and color within a single flow. Vegetation grows preferentially on the smoother pahoehoe slabs and significantly impacting the …

Ecology, Problem Framing And Local Land Use Controls: A Case Study Of Socio-Ecological Governance In Franklin County, Idaho, Alissa Salmore

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Due to the continuity of energy and material flows, the persistence of an ecological network necessarily includes a linking of ecological units from local and immediate to regional and broad-ranging scales. Humans are an integral part of ecosystems acting as resource consumers and agents of change, and all systems can be considered combined 'socio-ecological' systems. Where environmental and social systems lack coordination, mismatches between the temporal, spatial or functional scales at which these systems operate lead to resource use inefficiencies and the loss of ecosystem components and functioning. This case study of Franklin County, Idaho documents a recent land use …

Factors Influencing Epiphytic Lichen Communities In Aspen-Associated Forests Of The Bear River Range, Idaho And Utah, Paul C. Rogers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In western North America, quaking aspen (Populus tremuloides Michx.) is the most common hardwood in montane landscapes. Fire suppression, grazing, wildlife management practices, and climate patterns of the past century are some of the threats to aspen coverage in this region. Researchers are concerned that aspen-dependent species may be losing habitat, thereby threatening their long-term local and regional viability. Though lichens have a rich history as air pollution indicators, I believe that they may also be useful as a metric of community diversity associated with habitat change. To date, few studies have specifically examined the status of aspen's epiphytic lichen …

Southern Hills, Pocatello, Idaho: Wildlife Conservation/Development Study, Justin Kmetzsch

Undergraduate Honors Capstone Projects

The sagebrush grassland landscape has shaped aspects of southeastern Idaho culture and enhanced its rural economy. Sharptail grouse, sage grouse and mule deer hunting are deeply rooted in family traditions. Each fall thousands of residents head out into the field to hunt, camp and enjoy the autumn outdoors. Deer hunting and associated activities generate an estimated 240 million dollars annually, in the Idaho economy. More recently, watching and photographing mule deer and other sagebrush grassland species is increasing in popularity and economic significance. But, trends in land conversion and development threaten sagebrush grassland landscapes, the wildlife they sustain, and cultural …

Simulation Of Groundwater Flow In Cache Valley, Utah And Idaho, Barry Myers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A groundwater model of Cache Valley was created using MODFLOW. Steady-state calibration of the model demonstrated that recharge to the lower confined aquifer may occur along the margin of the valley that borders the Wellsville Mountains and the Bear River Range. Steady-state calibration also showed that discharge from the unconfined aquifer may occur along the eastern and western margins of the valley in both the Utah and the Idaho portions of the valley.

Two simulations were run with increased pumping of 3 5 cubic feet per second (1 cubic meter per second) from the principal aquifer. The first simulation was …

An Ecological/Life History Comparison Of Two Whitefish Species In Bear Lake, Utah/Idaho, Brett W. Thompson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ecological traits of the endemic Bear Lake whitefish Prosoopium abyssicola and the Bonneville whitefish prosopium silonotus were investigated. Spatial distributions indicated distinctive differences in depth contour preference. Catch per unit effort data indicated that Bonneville whitefish prefer shallow depths and warmer water temperatures, whereas Bear Lake whitefish prefer deep, cold water.

Diet differences between the two species were large. Differences in both age distribution and growth rate patterns were also observed. The Bonneville whitefish population was predominantly composed of juvenile age classes. Very large adults reached ages of 12-14 years. Bear Lake whitefish exhibited a different population structure with few …

Factors Affecting Spawning And Survival Of Bear Lake Bonneville Cutthroat Trout In St. Charles Creek, Idaho, Paul Burnett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I described the spawning ecology of the Bear Lake Bonneville cutthroat trout (BLBCT) in St. Charles Creek. I tracked cutthroat trout with used radio telemetry. I conducted redd counts to describe spawning conditions. Most cutthroat trout in the Big Arm strayed into the Bear River. Cutthroat trout migrations in the Little Arm and main fork were very limited (< 4 km). Redd distributions showed very similar patterns between 1989, 2000 and 2001 with most redds being built in the lowest kilometer of stream. Artificial fish transportation changed the redd distribution in 2002. More redds were built in the main fork and redds were distributed throughout the stream. Redds built in the main fork were characterized by lower levels of fine sediment and higher water velocities as compared to the redds built on the Little Arm. The results of this research will be used to aid resource managers in developing a management plan for wild BLBCT.

Seasonal Movements Of Fluvial Bonneville Cutthroat Trout In The Thomas Fork Of The Bear River, Idaho-Wyoming, Warren Colyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The majority of interior cutthroat trout (Oncorhynchus clarki) subspecies have been extirpated from large rivers by anthropogenic activities that have fragmented habitats and introduced non-native competitors. Selective pressures against migratory behaviors and mainstream river occupation and conservation schemes that isolate genetically pure populations above barriers have restricted gene flow and prevented the expression of fluvial life history traits in many populations. Existing knowledge about the movements and home range requirements of fluvial cutthroat trout is therefore limited. We implanted a total of 55 Bonneville cutthroat trout (BCT) in the Thomas Fork River, Idaho, with radio transmitters and located …

Morphometric Evaluation Of The Whitefish Complex In Bear Lake, Utah/Idaho, Alan Ward

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Whitefish populations around the world have long been difficult to categorize taxonomically. The whitefish of Bear Lake, Utah/Idaho are no exception. There are three recognized species of Prosopium that are endemic to the lake. Two of these species, Prosopium spilonotus and Prosopium abyssicota, have previously been indistinguishable outside of spawning times. Previous studies have proposed additional taxa within P. spi/onotus to further complicate the identification among these taxa.

Morphological characteristics were quantified on wild whitefish from Bear Lake, as well as from progeny reared in the laboratory from the wild adult fish. The purported taxa were separated in the field …

Preventive Predation Management: An Evaluation Using Winter Aerial Coyote Hunting In Utah And Idaho, Kimberly Kessler Wagner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To evaluate preventive aerial coyote hunting as a depredation management technique, I compared sheep losses to coyote (Canis latrans) predation and the hours of corrective predation management required on summer grazing areas with and without hunting the prior winter from helicopters. Correlations were used to test for relationships between the extent, intensity, and timing of aerial hunting and lamb losses to coyote predation. Data on the age, sex, and reproductive status of coyotes killed using aerial hunting on coyote populations.

Winter aerial hunting reduced confirmed and estimated lamb losses to coyote predation and the hours of effort required …

Aminostratigraphy Of Thatcher Basin, Se Idaho: Reassessment Of Pleistocene Lakes, Amy Hochberg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Quaternary geologic history of Lake Thatcher, southeastern Idaho, is pivotal in determining when the Bear River carved its through-flowing channel into the Bonneville Basin. Bright's reconstruction of the history of Lake Thatcher was based on ¹⁴C dates that are now known to be inaccurate. Lava Creek B ash found interbedded with lacustrine sediment suggests that Thatcher Basin contained a lake well before Bright's original estimate of 34 ka.

D/L ratios, which measure the extent of racemization in fossil gastropods, in conjunction with paleosols and tephra, were used to correlate between four localities across Thatcher Basin to reassess lake-level …

Seasonal Variation In The Species Composition, Abundance, And Size-Frequency Distribution Of Zooplankton In Bear Lake, Utah-Idaho, Edmundo G. Moreno

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bear Lake, a large oligotrophic lake (282 km²), was studied from October 1986 to December 1987 to determine the temporal changes in the zooplankton assemblage at one site in the pelagic zone and one in the littoral area. In this study, species composition, abundance, biomass, and size frequency distribution were determined. Additionally, chlorophyll a, water transparency, and temperature and oxygen profiles were measured to help interpret zooplankton changes during the study.

The zooplankton species assemblage comprised eight species of cladocera, seven species of copepods, and five species of rotifers. The abundance and biomass of the zooplankton assemblage, particularly …
