1996, Journal of Aquatic Animal Health (8) 37-46
From 1988 through 1992, we assessed the prevalence (frequency of occurrence) and severity (degree of infection) of Renibacterium salmoninarum (RS) among fish in marked groups of Columbia River basin and Snake River basin hatchery spring chinook salmon Oncorhynchus tshawytscha before release and during their seaward migration. During the study, prevalence of...

Allen I. Miller, L.G. Beckman
1996, Transactions of the American Fisheries Society (125) 338-340
We report the occurrence of white sturgeon Acipenser transmontanus eggs in guts of four species of fish from the Columbia River. Three of the species—northern squawfish Ptychocheilus oregonensis, largescale sucker Catostomus macrocheilus, and prickly sentpin Cottus asper—are native to the river and one, common carp Cvprinus carpio, is exotic....

A.G. Maule, R. M. Schrock, C. Slater, M.S. Fitzpatrick, C. B. Schreck
1996, Fish and Shellfish Immunology (6) 221-233
The immune –endocrine responses in spring chinook salmon (Oncorhynchus tshawytscha) were examined during their freshwater migration and final maturation. In 1990, migrating fish had high plasma cortisol titres (means 200 ng ml−1) and generated relatively few antibody-producing cells (APC) from peripheral blood leukocytes (PBL) (100 –200 per culture). After three...
The application of an analytic element model to investigate groundwater-lake interactions at Pretty Lake, Wisconsin
Randall J. Hunt, James T. Krohelski
1996, Lake and Reservoir Management (12) 487-495
Pretty Lake is a 64 acre, sandy-bottomed groundwater flow-through lake that has a history of hydrologic disturbance. Residents and regulators require a better understanding of lake-groundwater interaction to develop measures to protect the lake's hydrologic system and water quality. A groundwater flow model was constructed as a tool to synthesize...
A revised velocity-reversal and sediment-sorting model for a high-gradient, pool-riffle stream
D.M. Thompson, E.E. Wohl, R.D. Jarrett
1996, Physical Geography (17) 142-156
Sediment-sorting processes related to varying channel-bed morphology were investigated from April to November 1993 along a 1-km pool-riffle and step-pool reach of North Saint Vrain Creek, a small mountain stream in the Rocky Mountains of northern Colorado. Measured cross-sectional areas of flow were used to suggest higher velocities in pools than in <span...

Water quality . . . potential sources of pollution
Stephen Vandas, Frank Farrar (artist)
1996, Report
