Glaciers and water supply
Mark Meier

Sediment Transport in Streams in the Umpqua River Basin, Oregon
C. A. Onions
1969, Report
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...
Chronic oral DDT toxicity in juvenile coho and chinook salmon
Donald R. Buhler, Mary E. Rasmusson, W.E. Shanks
1969, Toxicology and Applied Pharmacology (14) 535-555
Technical and p,p′-DDT was incorporated into test diets and fed to juvenile chinook and coho salmon for periods as long as 95 days. Pure p,p′-DDT was slightly more toxic to young salmon than was the technical DDT mixture. Chinook salmon appeared to be 2–3 times more sensitive to a given concentration of...
Effect of feeding and of DDT on the activity of hepatic glucose 6- phosphate dehydrogenase in two salmonids
Donald R. Buhler, P. Benville
1969, Journal of the Fisheries Research Board of Canada (26) 3209-3216
The specific activity of liver glucose 6-phosphate dehydrogenase in yearling rainbow trout remained unchanged when the fish were starved for periods as long as 8 weeks and when starved animals were fed diets of various compositions. Injection of insulin concurrently with refeeding also failed to alter the specific activity of...
Comparison of thermal data from airborne and vessel surveys of Lake Erie
Alfred M. Beeton, James W. Moffett, Dana C. Parker
1969, Conference Paper, Proceedings of the 12th Conference on Great Lakes Research
A study of the applications of airborne infrared equipment for detecting water masses and currents of the Great Lakes is described. Infrared scanners were used to make thermal strip maps and an infrared radiometer was used to obtain surface temperatures of the western end of Lake Erie and the lower...
Environmental impact of the Big Cypress Swamp jetport
U.S. Department of the Interior
1969, Report
Development of the proposed jetport and its attendant facilities will lead to land drainage and development for agriculture, industry, housing, transportation, and services in the Big Cypress Swamp which will inexorably destroy the south Florida ecosystem and this the Everglades National Park....

The rapids and the pools - Grand Canyon: Chapter D in The Colorado River region and John Wesley Powell (Professional Paper 669)
Luna Bergere Leopold
1969, Professional Paper 669-D
Through the Grand Canyon the Colorado drops in elevation about 2,200 feet in 280 miles; most of this drop occurs in rapids that account for only 10 percent of the distance. Despite the importance of rapids, there are no waterfalls. Depth measurements made at 1/10-mile intervals show that the bed...
John Wesley Powell: Pioneer statesman of federal science: Chapter A in The Colorado River region and John Wesley Powell (Professional Paper 669)
Mary C. Rabbitt
1969, Professional Paper 669-A
In the middle decades of the 19th century, American science matured rather rapidly. The general scholar with an interest in natural history gave place to the specialist in a particular science, and the various sciences themselves became distinct from each other and from the general body of knowledge. The geological...
Landscape esthetics: How to quantify the scenics of a river valley
Luna Bergere Leopold
1969, Natural History 37-44
There are an increasing number of bills before Congress that in one way or another affect the landscape or the environment. Each of these requires seemingly endless numbers of congressional hearings, which are recorded upon endless reams of paper.And if, for some reason, you happen to read the voluminous testimony...
Stratified rocks of the Grand Canyon: Chapter B in The Colorado River region and John Wesley Powell (Professional Paper 669)
Edwin D. McKee
1969, Professional Paper 669-B
The record of the earth's history in the walls of the Grand Canyon has been deciphered through hard work by many people during the past 100 years. Much still remains unsolved. John Wesley Powell's contributions were of a pioneering type, though he was not the first to discuss the rocks...
Geologic history of the Colorado River: Chapter C in The Colorado River region and John Wesley Powell (Professional Paper 669)
Charles B. Hunt
1969, Professional Paper 669-C
John Wesley Powell clearly recognized that the spectacular features of the Colorado River - its many grand canyons - were dependent upon the structural history of the mountainous barriers crossed by the river. He conceived of three different historical relationships between rivers and structural features: (1) Newly uplifted land surfaces...
Hydrology of the San Luis Valley, south-central Colorado
P. A. Emery, A. J. Boettcher, R.J. Snipes, H.J. Mcintyre Jr.
1969, Report
An investigation of the water resources of the Colorado part of the San Luis Valley was begun in 1966 by the U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board. (See index map, fig. 1). The purpose of the investigation is to provide information for planning and implementing...
Epifauna and thermal additions in the upper Patuxent River estuary
R. L. Cory, J. W. Nauman
1969, Chesapeake Science (10) 210-217
In the upper Patuxent Estuary environmental changes in temperature, salinity, and turbidity over a 5-year period are linked to changes in epifaunal production and species distribution. During 1967 a series of monthly panels showed dry weight production averaged 2.8 times greater in a steam electric station...

A Devonian laterite has recently been discovered near Reshun in the Mastuj valley of Chitral State, West Pakistan. It is believed to be the fourth recorded Paleozoic laterite in the world. The laterite is entirely within a thick carbonate of the Shogram Formation of Upper Devonian (Frasnian) age. A chemical...

Compilation of hydrologic data, Green Creek, Brazos River basin, Texas, 1966
Trigg Twichell
1969, Report
In 1950 the U. S. Soil Conservation Service began construction of floodwater-retarding structures in Texas under authorities granted by the Congress. These authorities provide, where economically feasible, that the program be applied to tributary watersheds of 240,000 acres or less. The usual practice has been to control flood runoff from...
