Recreational activity is growing faster than facilities can be built to keep up with demand. This is evident during periods of peak use such as the summer for water based activities and the winter for snow related pursuits. During these periods of intense use, many recreationalists cannot
find the facilities...
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.
At the request of Dr. E.D. Perry, (23 August 1957), an evaluation was made of U.S. Fish and Wildlife Service River Basin Studies air and water temperature gathering program for the Snake River Basin. The only criteria was the desirability for data to be used to forecast temperature structures which...
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 presents a summary of the principal geologic and physiographic features of the upper part of the Snake River Canyon between Oregon and Idaho. The area discussed extends from Farewell Bend near Huntington, Oregon downriver to Granite Creek 6 miles below Hells Canyon Dam, a distance of 94 miles....
Hunter-gatherers depend on naturally occurring resources and, in order to survive, must overcome resource procurement challenges inherent in their environment. One challenge relates to the temporal and spatial availability of resources, which hunter-gatherers address, in part, through the strategic use of space to position themselves for optimal access to necessary...
The effects of fire severity on post-fire succession and shrub demography were quantified in shrub-steppe grasslands and subalpine forests in the Hells Canyon of the Payette National Forest, Idaho. Following the 1988 Eagle Bar Fire, species frequency, community diversity, fire adaptations, and stand ages were quantified at 12 plots in...
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.
