Summary of information on aquatic biota and their habitats in the Willamette Basin, Oregon, through 1995

Creator:: Altman, Bob, Henson, Colleen M., Waite, Ian R., United States. Fish and Wildlife Service, National Water-Quality Assessment Program (U.S.), and Geological Survey (U.S.)
Abstract:: This report reviews and summarizes available information on aquatic biological communities in the Willamette Basin through 1995. Specifically, the report describes (1) the distribution, abndance, and trends of three taxonomic groups--algae, macroinvertebrates, and fish--and, to a lesser degree, other selected semi-aquatic taxa (i.e., taxa frequenting but not living wholly in...

An investigation of alternative means of achieving water quality objectives

Creator:: Kerri, Kenneth Donald
Abstract:: Storage of water for water quality control is one of the alternative means of achieving water quality objectives. Authorities in the field of water quality management disagree regarding the use of precious water for the dilution of wastes. The costs of achieving water quality objectives by treatment of wastes at...

Benthic algal flora of four rivers of the middle Willamette River Basin

Creator:: Todd, Leona Esther
Abstract:: Fresh-water benthic river algae were collected from selected sites in Willamette River tributaries; two sampling sites were in the Yamhill River system and four sampling sites were in the Santiam River system. Twelve samples were taken at each collection site in the Yamhill River system at approximately monthly intervals from...

A three nest, humanly disturbed Great Blue Heron colony along the Willamette River, Linn County

Creator:: Bayer, Range D., 1947-
Abstract:: There were 21 days with observations during 30 January-21 May 1974. Herons were already displaying on January 30, so nesting activity can occur much earlier than has been supposed. A yearling was often seen at the nests, but most nesting activity was by adults. Although eggs were laid in at...

A spatially explicit method for determining the effects of watershed scale land use on stream conditions

Creator:: Kehmeier, Jonathan W.
Abstract:: The primary goal of this research was to identify the impacts that individual agricultural land uses have on fish communities in small streams located in the Willamette Valley of western Oregon. The diverse nature of the land use features of the valley provided a challenging but useful system for the...

A system analysis method for water quality management by flow augmentation

Creator:: Worley, John Larry
Abstract:: A rapid expansion of population and industrialization in recent years has created new and difficult problems in water resources management. Prudent management of water quality will require that more efficient methods be developed for evaluating large volumes of data on complex river systems, and tabulating the results in a form...
