A graph is presented which shows the average annual temperature depth profile which has been computed and estimated for the
Brownlee Reservoir. Forecast computations and estimations are
for a median river flow year. The graph also contains forecasts
of the annual temperature cycle for the Snake River below Brownlee Dam.
The mail boat trip was taken from Lewiston to Hells Canyon and return. Bathythermograph observations were made in deep holes at Buffalo Eddy, Nez Perce Dam site, and near Mountain Sheep Dam site. Thermograph sites on the Grande Ronde River were evaluated. A number of lakes, reservoirs, and dams were...
This report vas prepared at this time at the suggestion or the Director of Research of the Oregon Fish Commission. Most of the data upon which it is based were collected by Mr. L. D. Marriage and his assistants of the Oregon Fish Commission. These data are scheduled to be...
Graphs are presented which show the average annual temperature depth profile which has been established for a position one mile above Brownlee Dame. Forecasts are make for median river flow and low river flow years. The graphs also contain forecasts of the annual temperature cycle for the Snake River just...
A table is presented of the predicted average annual temperature for discharge water from Oxbow and Low Hells Canyon Dams. Forecast computations are for a median river flow year. The net effect of these two reservoirs on the thermal structure of the river will be small.
Most of the readily available unpublished hydrographic data for Oregon Estuaries which was collected prior to June 1956 have been tabulated, Data on water temperature salinity and velocity are presented. Data collected by the Navy Hydrographic Office and the USC & GS are not included.

Unpublished hydrographic data for Oregon Estuaries (Alsea, Columbia, Coos, Nehalem, Netarts, Siletz, Siuslaw, Tillamook, Umpqua, and Yaquina) which was collected by Oregon State College between June 1956 and September 1958 are tabulated.
