  • The Huron River History Book
    THE HURON RIVER Robert Wittersheim Over 15,000 years ago, the Huron River was born as a small stream draining the late Pleistocene landscape. Its original destination was Lake Maumee at present day Ypsilanti where a large delta was formed. As centuries passed, ceding lake levels allowed the Huron to meander over new land eventually settling into its present valley. Its 125 mile journey today begins at Big Lake near Pontiac and ends in Lake Erie. The Huron’s watershed, which includes 367 miles of tributaries, drains over 900 square miles of land. The total drop in elevation from source to mouth is nearly 300 feet. The Huron’s upper third is clear and fast, even supporting a modest trout fishery. The middle third passes through and around many lakes in Livingston and Washtenaw Counties. Eight dams impede much of the Huron’s lower third as it flows through populous areas it helped create. Over 47 miles of this river winds through publicly owned lands, a legacy from visionaries long since passed. White Lake White Lake Mary Johnson The Great Lakes which surround Michigan and the thousands of smaller lakes, hundreds of rivers, streams and ponds were formed as the glacier ice that covered the land nearly 14,000 years ago was melting. The waters filled the depressions in the earth. The glaciers deposited rock, gravel and soil that had been gathered in their movement. This activity sculpted the land creating our landscape. In section 28 of Springfield Township, Oakland County, a body of water names Big Lake by the area pioneers is the source of the Huron River.

  • Lesson 4: Sediment Deposition and River Structures
    LESSON 4: SEDIMENT DEPOSITION AND RIVER STRUCTURES ESSENTIAL QUESTION: What combination of factors both natural and manmade is necessary for healthy river restoration and how does this enhance the sustainability of natural and human communities? GUIDING QUESTION: As rivers age and slow they deposit sediment and form sediment structures, how are sediments and sediment structures important to the river ecosystem? OVERVIEW: The focus of this lesson is the deposition and erosional effects of slow-moving water in low gradient areas. These “mature rivers” with decreasing gradient result in the settling and deposition of sediments and the formation sediment structures. The river’s fast-flowing zone, the thalweg, causes erosion of the river banks forming cliffs called cut-banks. On slower inside turns, sediment is deposited as point-bars. Where the gradient is particularly level, the river will branch into many separate channels that weave in and out, leaving gravel bar islands. Where two meanders meet, the river will straighten, leaving oxbow lakes in the former meander bends. TIME: One class period MATERIALS: . Lesson 4- Sediment Deposition and River Structures.pptx .

  • Classifying Rivers - Three Stages of River Development
    Classifying Rivers - Three Stages of River Development River Characteristics - Sediment Transport - River Velocity - Terminology The illustrations below represent the 3 general classifications into which rivers are placed according to specific characteristics. These categories are: Youthful, Mature and Old Age. A Rejuvenated River, one with a gradient that is raised by the earth's movement, can be an old age river that returns to a Youthful State, and which repeats the cycle of stages once again. A brief overview of each stage of river development begins after the images. A list of pertinent vocabulary appears at the bottom of this document. You may wish to consult it so that you will be aware of terminology used in the descriptive text that follows. Characteristics found in the 3 Stages of River Development: L. Immoor 2006 Geoteach.com 1 Youthful River: Perhaps the most dynamic of all rivers is a Youthful River. Rafters seeking an exciting ride will surely gravitate towards a young river for their recreational thrills. Characteristically youthful rivers are found at higher elevations, in mountainous areas, where the slope of the land is steeper. Water that flows over such a landscape will flow very fast. Youthful rivers can be a tributary of a larger and older river, hundreds of miles away and, in fact, they may be close to the headwaters (the beginning) of that larger river. Upon observation of a Youthful River, here is what one might see: 1. The river flowing down a steep gradient (slope). 2. The channel is deeper than it is wide and V-shaped due to downcutting rather than lateral (side-to-side) erosion.

    Lake Restoration Program 2020 Report and 2021 Plan A cooperative dredging project between DNR and the City of Council Bluffs removed over 500,000 CY of sand from Lake Manawa (Monona County), providing materials for a local levee-building project and improving water quality within the lake. Watershed ponds, constructed at West Lake Park in Scott County, will protect the four lakes in the Lake of the Hills Complex for many years. Mariposa Lake (Jasper County) following restoration, completed in 2020. The project included building two new ponds in the park to protect the lake, dredging, shoreline stabilization, and fish habitat. Submitted To Joint Appropriations Subcommittee on Transportation, Infrastructure, and Capitals and Legislative Services Agency 1 Executive Summary The Fiscal Year 2020 Iowa Lake Restoration Report and Fiscal Year 2021 Plan provides a status of past appropriated legislatively directed funding; outlines the future needs and demands for lake restoration in Iowa; and identifies a prioritized group of lakes and the associated costs for restoration. Iowans value water quality and desire safe healthy lakes that provide a full complement of aesthetic, ecological and recreational benefits. A recently completed water-based recreational use survey by Iowa State University found that six of 10 Iowans visit our lakes multiple times each year and spend $1.2 billion annually in their pursuit of outdoor lake recreation. The most popular activities are fishing, picnicking, wildlife viewing, boating, hiking/biking, swimming and beach use. In addition, visitations at lakes that have completed watershed and lake improvements efforts continue to exceed the state average and their own pre-restoration visitation levels.

Signed Pauline Dieras Date: 05/03/2013 i Abstract Oxbow lakes are of high ecological importance due to the number and the diversity of habitats they provide. They are created after the abandonment of meanders and subsequent sediment infilling leads to their progressive terrestrialisation, taking from a few months up to several centuries. Nonetheless, little is known about oxbow lake terrestrialisation processes, sediment composition, or why such a disparity exists in lakes’ longevity. To understand the controls on oxbow lakes alluviation, field observations, remotely sensed data and GIS analyses were combined. Sediment transfers in oxbow lakes were documented by topographic and sampling surveys of sites in France and Wales.

  • OXBOW LAKE (BROWNWATER SUBTYPE) Concept: Oxbow Lakes Are Permanently Flooded Open Water Depressions in Large Floodplains, Isolat
    OXBOW LAKE (BROWNWATER SUBTYPE) Concept: Oxbow Lakes are permanently flooded open water depressions in large floodplains, isolated from the river by channel shifts. Most are largely unvegetated, but they may contain sparse vegetation or patches of woody or herbaceous wetland plants of various kinds. The Brownwater Subtype covers those along brownwater rivers, which receive substantial mineral sediment input. They typically have an edge zone containing Taxodium distichum, Nyssa aquatica, Platanus occidentalis, or Betula nigra. Distinguishing Features: Oxbow Lake communities are distinguished from Cypress–Gum Swamps by being wet enough to lack a closed tree canopy. They are distinguished from Semipermanent Impoundment communities by occurring in closed, undammed basins created by an abandoned river channel. This setting produces an aquatic community that is isolated from both the river and from stream input except in floods. The Brownwater Subtype can usually easily be distinguished by the character of the river and the occurrence of brownwater communities adjacent to it. It typically has an edge zone containing brownwater species such as Platanus occidentalis or Fraxinus pennsylvanica as well as the more widespread Taxodium distichum and Betula nigra. Synonyms: Not covered in NVC. Ecological Systems: Atlantic Coastal Plain Small Brownwater River Floodplain Forest (CES203.250). Sites: Oxbow Lake communities occur in large floodplains in segments of former river channels that have become isolated from the river by channel shifts. Deposition along the new river course has closed them off, turning them into basins that hold permanent water and are not connected to the river except during floods. Soils: Oxbow Lake soils are treated as inclusions or mapped as water in soil surveys.

Volume 5, Issue 6 (Nov. - Dec. 2012), PP 32-39 Www.Iosrjournals.Org A Journey Toward Oxbow Lake Formation and Associated Change in Human Mosaic: Study on Kalindri River of Malda District Dr. Swades Pal1, Shyamal Kumar Kar2 1Assistant Professor, Deptt. of Geography, University of Gour Banga, West Bengal 2Research Scholar, Deptt. of Geography, Visva-Bharati, West Bengal Abstract: This paper aims to illustrate the phases of oxbow lake formation in Kalindri river adjacent of Naogharia region and how over time being these oxbow lakes have converted into wetlands of multifaceted resource pools. At the same time it is also being attempted to show how the dynamics of river course is entangled with dynamism of population migration, settlement shifting, occupational shifting, and change of economic activities. Consultations of some old maps, local peoples’ perceptions, time to time field survey etc. have done to prepare this article. It is found that two successive oxbow lakes formation and frequent over spilling events have direct impact on shifting of higher class population and settlement but the soil Childs are more interested to adjust with the situation. Poor sections of people have been adjusting themselves with changing physical setup and they have no anguish for frequent rehabilitation. Process of oxbow lake formation has also generated an excellent fertile land and which is considered to be a agricultural hotspot. Similarly, formation of oxbow lake wetland has generated good livelihood stability with ample opportunities of fishing, shelling, crabbing, hydrophytic vegetable production, wetland based irrigation non monsoon agriculture practices etc.

  • The Significance of Oxbow Lakes for the Ecosystem of Afforested River Valleys
    JOURNAL OF WATER AND LAND DEVELOPMENT J. Water Land Dev. No. 13a, 2009: 115–131 The significance of oxbow lakes for the ecosystem of afforested river valleys Józef KOC, Szymon KOBUS, Katarzyna GLIŃSKA-LEWCZUK University of Warmia and Mazury in Olsztyn, Department of Land Reclamation and Environment Management, ul. Plac Łódzki 2, 10-719 Olsztyn, Poland; e-mail: [email protected] Abstract: The interest in significance of forest areas in water quality improvement has been increas- ing since creation of biogeochemical barriers became effective tools against the input of pollutants to surface water from diffuse sources. Along meandering river valleys, numerous floodplain lakes often appear as valuable water ecosystems but of advanced eutrophy. Their trophic status depends not only on the hydrological connectivity with the river but also land use in the direct vicinity of the reservoir. Research on water ecosystems in the postglacial river valleys in northern Poland contributed to iden- tification of the role of woodland area in pollutants migration in the valley of the Łyna River. The study on the ecosystem concerned seasonal variation in nutrient concentrations (N and P) and bottom sediments properties in relation to hydrological conditions (water level fluctuations). Based on the collected data we attempted prediction of the reservoir lifetime. Depending on hydrological, geological and topographic conditions the origin of water supply of the basin is changing. Annual water level fluctuations in the range of 200 cm cause the basin capacity variation as much as 5 times. Nevertheless, water quality in the lake was conditioned by the riverine supply, the significant share in the lake feeding has groundwater supply from hillslope aquifer and seepage through alluvial aquifer.
