  Citation × Citation Citation Abstract Copy Title: Progress Reports 2017, Distribution and Abundance of Pit Sculpin in Drews and Camp Creeks, Oregon Abstract -- Pit Sculpin Cottus pitensis are endemic to Goose Lake basin, south-central Oregon. The species was listed as sensitive by the U.S. Forest Service Region 6 and Bureau of Land Management and by the State of Oregon. Recent surveys suggested Pit Sculpin have a restricted range in Oregon. The objectives of our surveys were to: 1) describe the current distribution and estimate the abundance of Pit Sculpin in Drews and Camp creeks, 2) describe the fish assemblages in Drews and Camp creeks, and 3) describe stream habitat conditions and collect habitat covariate data at each sampling location for modelling capture probabilities and abundance. We found Pit Sculpin distribution was limited to approximately 5.2 km of Drews Creek and 0.8 km of Camp Creek. Pit Sculpin primarily occupied riffles with gravel substrate. We estimated 12,331 and 1,518 Pit Sculpin in Drews and Camp creeks, respectively.

  Citation × Citation Citation Abstract Copy Title: Lake and Stream Survey Whitman National Forest Abstract -- This is the second report of the conditions existing in the lakes and streams of the Whitman National Forest, Region 6. The first survey, conducted in the summer of 1938, and this survey, conducted in the summer of 1939, were under the supervision of the Whitman National Forest. The purpose was to determine the need for lake and stream improvements on the Whitman National Forest. To develop a practical stocking program. To determine whether or not present fishing regulations are satisfactory and to recommend such changes as seem advisable.

  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.
