ABSTRACT Most of the dams built by the Bureau of Reclamation were completed before environmental regulations such as the Clean Water Act, National Environmental Protection Act, or Toxic Substances Control Act existed. The management and operation of dams was instituted under conditions where the ecology of the downstream habitat was unknown and largely ignored. Changing or modifying structures, flow regimes, and land use patterns are some of the efforts being pursued by the Bureau to reconcile or mitigate the effects of impoundment to comply with these environmental policies and to maximize the potential for recreation, fisheries, and water quality in tailwater habitats for the water resource users. The purpose of this report is to provide a reference document intended to aid in the management, compliance, and problem solving processes necessary to accomplish these goals in Bureau tailwater habitats. This report was organized by categorizing each reference with the Bureau region in which the information originated. Each of the five regions is discussed in a separate section, with each section containing a complete bibliographic reference for each literature citation. Included with each bibliographic entry is additional information about the State, county, dam, and drainage associated with the literature. A subject code is also listed that categorizes the literature into one of five main subject categories, and one or more letters that may indicate specific subcategories, Each regional section of this report begins with a discussion of the information available for that region, problem tailwater areas, and a discussion of the literature covering the five subject categories. This will allow the user to locate a tailwater by region, State, county, or drainage; and to determine if any literature is available for that tailwater and what subjects that literature covers. 17.

Campbell Environmental Sciences Section Applied Sciences Branch Research and Laboratory Services Division Denver Office Denver, Colorado January 1990 UNITED STATES DEPARTMENT OF THE INTERIOR * BUREAU OF RECLAMATION ACKNOWLEDGEMENTS The references for this report were acquired by personnel from the Denver Office Library over an 18-month period. This task was both difficult and labor intensive, and their efforts are greatly appreciated. Dr. K. A. Barrick prepared the index cards for this report that contain all the informa- tion presented in the bibliographic sections and a short abstract of the document. His work was the basis for the entire report. Thanks are also due to all the regional personnel in the planning and environmental offices who provided informa- tion, references, and reviews on their region’s section of the report. Mission: As the Nation’s principal conservation agency, the Department of the Interior has responsibility for most of our nationally-owned public lands and natural and cultural resources. This includes fostering wise use of our land and water resources, protecting our fish and wildlife, preserving the environmental and cultural values of our national parks and historical places, and providing for the enjoyment of life through outdoor recreation. The Department assesses our energy and mineral resources and works to assure that their development is in the best interests of all our people. The Department also promotes the goals of the Take Pride in America campaign by encouraging stewardship and citizen responsibility for the public lands and promoting citizen participation in their care. The Department also has a major responsibility for American Indian reservation communities and l for people who live in Island Territories under U.S. Administration.
