Smallmouth Bass Seasonal Dynamics in Northeastern South Dakota Glacial Lakes
… bass were introduced into many South Dakota lakes in the late 1980’s and the introductions have resulted in many self-sustaining populations. As smallmouth bass become more popular in South Dakota there is a need to better manage these smallmouth bass populations. The objectives of this study …

Food Habits of Yellow Perch in Eastern South Dakota Glacial Lakes
… were collected fron1 eastern South Dakota lakes with short-term sets of experimental gill nets. Yellow perch food habits were documented and related to population form and function characteristics. A wide range of yellow perch population types were identified. Higher-quality yellow perch …

Population Dynamics of Common Carp in Eastern South Dakota Glacial Lakes
… carp collected from five eastern South Dakota lakes. All common carp were collected using day-time electrofishing and each carp was assigned an identification number, measured to the nearest millimeter total length, and aging structures were removed. Scales, vertebrae, opercles, pectoral fin …

Population Dynamics and Management of Yellow Perch Populations in South Dakota Glacial Lakes
… from the larval stage until age 1 in six glacial lakes located in eastern South Dakota in order to determine whether year-class strength could be indexed at the larval stage. Variation in annual peak larval abundance varied among years within lakes. In East 81 Slough, Sinai, and Waubay …

Influence of Gizzard Shad on Fish Community Ecology in Northeastern South Dakota Glacial Lakes
… of gizzard shad in two northeastern South Dakota glacial lakes and 2) determine the impacts gizzard shad on the population dynamic rates and seasonal diets of both walleye and yellow perch in northeastern South Dakota glacial lakes. To determine the effects that gizzard shad had on walleye and …

Factors Regulating Walleye Early Survival and Cohort Strength in Eastern South Dakota Glacial Lakes
… vitreus is an important ecological component of glacial lake aquatic communities in eastern South Dakota, and the most popular sport fish in the region. Walleye populations in this region exhibit consistently poor or annually-variable reproductive success and are regularly stocked in an effort to …

Yellow Perch Recruitment and Potential Interactions with Smallmouth Bass in Eastern South Dakota Glacial Lakes
… perch across a range of eastern South Dakota glacial lakes. Production of larval yellow perch was moderately synchronous among spatially segregated systems and variation in larval density was influenced by the Moran Effect during the post-egg mass emergence period. Specifically, increased …

Structure and Dynamics of Largemouth Bass Populations in Eastern South Dakota Glacial Lakes and Large Impoundments
… sample largemouth bass in South Dakota natural lakes is during late spring-early summer when water temperatures are 16-22°C. I sampled largemouth bass populations from six glacial lakes and three large (i.e.,> 60 ha) impoundments in eastern South Dakota to determine population structure …

Assessing the Sustainability of Fish Communities in Glacial Lakes: Habitat Inventories and Relationships Between Lake Attributes and Fish Communities
… variables and the fish communities in large lakes. The objectives of my research were to: 1) quantify the available aquatic habitats in 15 South Dakota large lakes, 2) investigate the use of Geographical Information System technology to create aquatic habitat layers, and 3) determine the …

Interannual Variation in Larval Yellow Perch Abundance in Eastern South Dakota Glacial Lakes and Relation to Sympatric Walleye Populations
… are a popular sportfish in eastern South Dakota glacial lakes. In addition to their recreational importance, yellow perch serve as a prey species for predators. Thus, understanding the factors that affect yellow perch population dynamics is a top priority among fishery managers in South Dakota. …

An Evaluation of Yellow Perch Perca flavescens Mortality in South Dakota
… for yellow perch populations in South Dakota glacial lakes. Total annual mortality has been previously quantified by researchers. However, total annual mortality is compensatory and does not quantify the separate contributions of both natural and fishing mortality. Thus, the means by which …

Quaternary geology of the Campbellford, Trenton, Consecon, Tweed, Belleville, Wellington, Sydenham, Bath, and Yorkshire Island map-areas, Ontario /
… Valley was ice filled at this time. High level glacial lakes fronted the ice during deglaciation. These waters quickly fell to low levels as the ice retreated from the St. Lawrence Valley, opening lower outlets.

Late Pleistocene Stratigraphy And Events In The Asbestos-valcourt Region, Southeastern Quebec
… of the Asbestos-Valcourt region indicates that glacial sediment deposite during at least two regional glacial advances underlie Late Wisconsinan ice-contact and glaciolacustrine sediments. Glaciolacustrine sediments (unit B), which underlie surface till (drift unit C), were deposited during a …

Food Habits and Diet Overlap of Age-1 and Older Walleye and White Bass in Lake Poinsett, South Dakota
… vitreum coexist in several of the large glacial lakes in eastern South Dakota. I collected age-1 and older white bass and walleye in Lake Poinsett, South Dakota during May, July and September, 1998 to determine food habits and diet overlap using percent by weight to describe diets and …

Exploring Interactions Between Walleye and Smallmouth Bass in South Dakota Waters
… in two Missouri River reservoirs and five glacial lakes to indirectly determine whether bass introductions have affected South Dakota walleye populations. I compared relative abundance, size structure, condition, growth, and total annual mortality for both species where available. Of the 26 …

Influence of Reproductive Habitat and Potential Competition on Yellow Perch Populations in Eastern South Dakota Lakes
… throughout their range. In eastern South Dakota, glacial lakes with erratic yellow perch recruitment tend to be shallow and lack structure. Because many lakes in South Dakota have limited structure, management efforts may include habitat manipulation as a tool to enhance yellow perch recruitment. …

Glacial geology of the north half of Barnes County, North Dakota
<p>The geomorphology and glacial geology of the north half of Barnes County in east central North Dakota is described and interpreted. The area comprised a portion of the Western Lake section of the Central Lowland province and was informally designated the Middle Sheyenne River area without …

Sedimentology and Stratigraphy of Glacial Lake Souris, North Dakota: effects of a glacial-lake outburst
<p>Glacial-lake outbursts commonly occurred along the southern margin of the Laurentide Ice Sheet as ice-marginal lakes suddenly drained. These outbursts released huge volumes of water with tremendous erosive potential, forming large trench-shape channels. Although glacial-lake spillways have been …
