Download or read book Effects of High Flow Experiments from Glen Canyon Dam on Abundance Growth and Survival Rates of Early Life Stages of Rainbow Trout in the Lees Ferry Reach of the Colorado River written by U.S. Department of the Interior and published by CreateSpace. This book was released on 2014-03-04 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-flow experiments (HFEs) from Glen Canyon Dam are primarily intended to conserve fine sediment and improve habitat conditions for native fish in the Colorado River as it flows through Grand Canyon National Park, Arizona. These experimental flows also have the potential to affect the rainbow trout (Oncorhynchus mykiss) population in the Lees Ferry tailwater reach immediately below the dam, which supports a highly valued recreational fishery and likely influences the abundance of rainbow trout in Grand Canyon. Understanding how flow regimes affect the survival and growth of juvenile rainbow trout is critical to interpreting trends in adult abundance. This study reports on the effects of HFEs in 2004 and 2008 on early life stages of rainbow trout in the Lees Ferry reach on the basis of monthly sampling of redds (egg nests) and the abundance of the age-0 trout (fertilization to about 1 to 2 months from emergence) and their growth during a 7-year period between 2003 and 2009.

Barber and published by . This book was released on 1988 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: "An instream flow study was conducted on Chamokane Creek using the lnstream Flow Incremental Methodology (IFIM). The purpose of this study was to: (1) determine the optimum flow for brown trout (Salmo trutta Linnaeus), rainbow trout (Salmo gairdneri Richardson), and sculpins, the majority of which are Piute sculpins (Cottus beldingi Eigenmann and Eigenmann); (2) recommend a minimum instream flow regime that would protect brown trout, rainbow trout, and sculpin habitat; and (3) determine the impact that proposed groundwater withdrawals will have on the availability of brown trout, rainbow trout, and sculpin habitat"--Document.
Download or read book Habitat Suitability and Availability for Rainbow Trout Oncorhynchus Mykiss in the Canyon Reservoir Tailrace and Evaluation of Side Scan Sonar for Habitat Mapping in a Semi wadable River written by Greg A. Cummings and published by . This book was released on 2015 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rainbow Trout Oncorhynchus mykiss are typically stocked in tailraces across the southeastern United States to mitigate fish habitat and assemblage alterations caused by large impoundments. Hypolimnetic discharges from Canyon Reservoir have created conditions suitable for a coldwater tail race fishery and trout have been stocked there since 1966. Changes in habitat availability for adult Rainbow Trout with discharge rate were examined to provide flow and habitat improvement recommendations for the Canyon Reservoir tailrace. Physical habitat modeling incorporated habitat suitability information for trout coupled with hydraulic modeling to assess habitat quality and quantity at various flow rates. Habitat mapping included traditional surveying, remote sensing, bathymetric mapping, and side scan sonar. Side scan sonar was evaluated for efficiency and applicability to river systems similar to the tailrace. Results indicate that summer water temperature is likely the primary limiting factor for adult trout survival and could impose limitations on physical habitat during critical summer months. Modified flow rates and habitat improvement could cause a potential increase in adult trout abundance and assist put-grow-and-take strategies in the upper portion of the tailrace. Side scan sonar provided efficient mapping of non-wadable sections of the study area. Challenges related to water level, access, navigability, positional accuracy, and post-processing were overcome. Trial runs, training, map accuracy assessments, and technological development will improve the effectiveness of this technique.

Download or read book Skeena River Fish and Their Habitat written by Allen Gottesfeld and published by Oregon State University Press. This book was released on 2008 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: British Columbia¿s Skeena River is one of the great salmon rivers of the North Pacific. The river and its fish have supported indigenous peoples for thousands of years. More recently, the Skeena has earned world renown for its recreational fishery and magnificent wilderness setting. Yet, over the last century, fish populations have declined from overfishing, habitat alteration and, to an unknown degree, climate change. Development of mining as well as oil and gas resources may also pose threats to fish populations.This book presents the first thorough review of the salmon stocks and freshwater species of the Skeena River. Initial chapters summarize the river¿s environment, fish, and fisheries. The book then examines the physical geography, development history, indigenous use, and major salmon stocks of each of the watershed¿s sub-basins. This volume makes available for the first time¿to researchers, field biologists, fishermen and natural history enthusiasts¿both the published, and largely unpublished, literature on this productive salmon ecosystem.

Download or read book Forest Hydrology written by Devendra Amatya and published by CABI. This book was released on 2016-09-14 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.

Download or read book The Archive of Place written by William Turkel and published by UBC Press. This book was released on 2011-11-01 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Archive of Place weaves together a series of narratives about environmental history in a particular location � British Columbia's Chilcotin Plateau. In the mid-1990s, the Chilcotin was at the centre of three territorial conflicts. Opposing groups, in their struggle to control the fate of the region and its resources, invoked different understandings of its past � and different types of evidence � to justify their actions. These controversies serve as case studies, as William Turkel examines how people interpret material traces to reconstruct past events, the conditions under which such interpretation takes place, and the role that this interpretation plays in historical consciousness and social memory. It is a wide-ranging and original study that extends the span of conventional historical research.

Download or read book The Letters and Journals of Simon Fraser 1806 1808 written by W. Kaye Lamb and published by Dundurn. This book was released on 2007-05-30 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: B.C. journalist Stephen Hume has said that fur trader and explorer Simon Fraser should be celebrated as the founder of British Columbia. Certainly, the achievements of the Scottish-descended United Empire Loyalist adventurer were impressive. During three extraordinary years, 1805-1808, Fraser undertook the third major expedition (after Alexander Mackenzie’s and Lewis and Clark’s) across North America, culminating in his famous journey down the river in British Columbia that now bears his name. Employed by the Montreal-based North West Company, Fraser was responsible for building many of British Columbia’s first trading posts. His exploratory efforts helped lead to Canada’s boundary later being declared at the 49th parallel. In this new volume, librarian and archivist W. Kaye Lamb provides a detailed introduction as well as illuminating annotations to Fraser’s journals, which were originally published by Macmillan of Canada in 1960.
