PISHES, LAHONTAN SYSTEM OF NEVADA AND NORTHEASTERN CALIFORNIA. 77 



seems to be more successful when the water is ruffled by the wind. It should be attempted only when 

 the trout are feeding near shore. Large minnows and an occasional Sacramento sunfish were caught in 

 this way in Pyramid and Winnemucca Lakes. 



The large trout seldom rise to the artificial fly except at times in the high Sierras. The same species 

 when living in the rivers and in their rapid and cool tributaries furnish excellent sport for the angler. 

 All recommend small flies, 12 to 16, and not in great variety .« Many of the smaller desert streams are so 

 closely lined with dense brush as to make fly fishing quite out of the question. Here the angler should 

 provide himself with a short bait rod, use worms and grasshoppers, and be prepared for a trout weighing 

 2 or 3 pounds. 



Salmo aquilarum, new species. Eagle Lake trout. 



The trout of Eagle Lake is allied to the trouts of the western slopes of the Sierras, but is not closely 

 related to the cutthroat of the Lahontan system. It is distinguished by the robust body with a deep

o The expressed opinions of some successful anglers may serve as a guide to one who has not fished in the region. 



Fred A. Gladding: "From Tnickee to near Reno, royal coachman, professor, ginger quill, march brown; from near Reno 

 downstream to near Glendale, gray drake, stone fly, hare's ear, and wren tail; June and July." 



George T. Mills: " For eastern slope of the Sierras, alder, pale evening dun, imbrie. bee, fern fly, and blue bottle." 



Prof. R. L. Green: "Sierras above Lake Tahoe, Governor Alvord; sometimes change to a fly not often used in the region." 



George I. James: "For the Trackee, royal coachman, professor, march brown, white miller, cow dung, ginger quill, blue

George G. Schweis: "Tnickee, blue quill, pheasant, royal coachman, professor (assorted). Quills most satisfactory, espe- 

 cially during low, clear water when the fish are shy." 



Morton's gun store, Reno: "We sell most of royal coachman, ginger quill, blue quill, red spinner, golden spinner, professor, 

 and red ant. Dry flies not generally useful because of turbulent water."
