Magnitude and frequency of floods in the United States: Part 9. Colorado River Basin
James L. Patterson, William P. Somers
1966, Water Supply Paper 1683
This report outlines methods by which the magnitude and frequency of expected floods of any recurrence interval from 1.1 to 50 years can be determined at most points in the Colorado River basin.Composite frequency curves were drawn showing the relation of the mean annual flood to floods having recurrence intervals...
Evaluation of p,p'-DDT as a reference toxicant in bioassays
Leif L. Marking
1966, Investigations in Fish Control 10
p,p'-DDT was tested as a reference standard toxicant against 19 species of freshwater fish, including 39 lots from 10 sources. In particular, the rapidity, nonselectivity, and consistency of its toxicity to fish were evaluated in 96-hour static bioassays. The chemical was rapidly and consistently toxic to lake trout, carp, green...
Temperature of surface waters in the conterminous United States
James F. Blakey
1966, Hydrologic Atlas 235
