Temperature and Salinity Observations in the
Umpqua River Estuary, July - October 1972 1/
I t~TRODUCT I ON
During the summer of 1972
ZH
distribution of fish populations.
sampled the Umpqua River estuary to determine
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 witl1in the estuary
and be useful when comparing information among estuaries.
Since the temperature
and salinity data are somewhat bulky and presumably valuable to persons not
necessarily interested in the results of the biological aspects of the study,
the information Is presented here as a separate report.
Hydrographic data of the Umpqua River estuary are scarce.
Surt (1 956)
reported temperatures, salinities, and v1ater currents measured at various depths,
locations, and tidal heights In the estuary for several days in 1955 and 1956.
The most distant station sampled by Gurt Has 11.7 nautical miles (23.9 km)
upstream from the ocean.
factors at
t\1'10
burt also showed the temporal changes in these physical
stations over a 40-hour period in July 1955 and at one station
over a 15-hour period in January 1}56.
Burt and ilcAiister (1;)59) described and
classified the salinities and currents of the Umpqua River estuary , as well as
those of
ot~er
Oregon estuaries, based on the same data collected by Burt in
1)55 and U56.
THE STUDY AREA
The Umpqua
~iver
drains approximately 1.4 million hectares (2.47 million
acres) and empties into the Pacific Ocean near the to\l'm of Hinchester Bay on
the central Oregon coast (Figure 1).
The average mean water discharge is
approximately 210 rn3/sec (7,475 cfs) near Elkton, Oregon, at river ki lorneter :;1.4

Service under the Anadromous Fish Aat PL 89-304.
