Temperature and salinity observations in the Umpqua River estuary, July-October, 1972

Creator:: Mullen, Robert E.
Abstract:: During the summer of 1972 we sampled the Umpqua River estuary to determine distribution of fish populations. As a part of that study temperature and salinity data were collected monthly throughout the estuary. The environmental data should help explain the distributions of various fishes within the estuary and be useful...

1993 Calf Creek migrant trapping results and juvenile steelhead (Oncorhynchus mykiss) emigration estimate

Creator:: Harkleroad, Glenn R.
Abstract:: Trapping migrating steelhead trout smolts was done in the spring and early summer of 1993 as part of the 1990 Umpqua National Forest Land and Resource Management Plan. Calf Creek was monitored to "validate smolt output estimates" and to "determine if changes in habitat quality are occurring." (Introduction)

Studies of the scales of Umpqua River spring chinook salmon

Creator:: Saltzman, Bill
Abstract:: A study of the scales of Umpqua River spring chinook salmon was made from mid-September to December 1, 1951. The study was undertaken to determine the age composition and probable life history of spring Chinooks in this river. The study was made at the Oregon State College Fisheries Research Laboratory...

Sediment transport in streams in the Umpqua River Basin, Oregon

Creator:: Onions, C. A. and Douglas County (Or.)
Abstract:: This report presents tables of suspended-sediment data collected from 1956 to 1967 at 10 sites in the Umpqua River basin. Computations based on these data indicate that average annual suspended-sediment yields at these sites range from 137 to 822 tons per square mile. Because available data for the Umpqua River...

The occurrence and distribution of fish in the Umpqua River Estuary, June through October 1972

Creator:: Mullen, Robert E.
Abstract:: The Umpqua River estuary was seined and gilinetted during the summer of 1972 to estimate the composition and distribution of fishes. The number of species collected at most sites averaged from four to six per seine haul and was relatively constant throughout the estuary. The number of fish collected per...

Physical and chemical oceanographic data : Umpqua River Estuary, Oregon ; Part IV, April 26-27, 1961

Creator:: Callaway, Richard J.
Abstract:: Oceanographic data collected in the Umpqua River Estuary, Oregon, during the period April 26-27, 1961, are tabulated. Temperature, salinity, velocity, and dissolved oxygen were observed at various depths over one tidal cycle at a mid-channel anchor station located near the mouth of the river.
