  Citation × Citation Citation Abstract Copy Title: Survey of the Waters of South Umpqua Ranger District, Umpqua National Forest, 1937 Abstract -- The objectives of the present survey of the upper waters of the South Fork of the Umpqua River were to: (1) develop practical and scientifically sound stocking policies; (2) determine the need for stream and lake improvements; and (3) obtain facts to assist in the settlement of the controversy with regard to the South Umpqua Falls. There has been continual demand by sportsmen that the South Umpqua Falls be supplied with fish ladders to permit safe ascent of sea-run species to spawning grounds above the falls. Study of this problem was undertaken as a definite part of the survey work described herein. The stream run and lake survey work was initiated by the Forest Service in cooperation with the U.S. Bureau of Fisheries during the summer of 1937. Emphasis was placed on the detailed studies relating to the physical and biological factors upon which it would be possible to recommend adequate stocking policies. No study of chemical conditions whatsoever was made for two reasons, first, lack of equipment prevented making gas analyses and, second, such studies seemed unnecessary by reason of the fact that there is no pollution present in the streams surveyed and all of them are well aerated, clean, rapid flowing mountain streams. Chemical conditions as shown by general observations were quite suitable and it is only whore natural or artificial pollutants occur in great abundance that chemical analyses would aid in determining tho basic effects of some of those fishes and their food organisms present in streams.
