346 EEPOKT OF COMMISSIONER OF FISH AND FISHERIES. 



canyon is a pretty little fall, 70 feet in height. Only two species offish 

 ■were found, Semotilus and Bhinichthys. Trout would probably live in 

 this stream, since the temperature in the canyon was 53J°. 



Deer Creel: rises in the Laramie Mountains and flows northeast into 

 the North Platte at Glenrock, Wyo. It is a small stream, not over 15 

 feet in width at its mouth at the time examined, but this was during 

 the dry season and much of the water was used above for irrigating 

 purposes. The stream did not average more than G inches deep at the 

 mouth ; the water was clear, and the temperature 01£°. 



Little Deer Creel:, a tributary of Deer Creek, flows out of a canyon in 

 the Laramie Mountains on the ranch of Major Wolcott, about 7 miles 

 south of Glenrock. It is a very pretty little mountain stream, discharging 

 about 1,(500 gallons of water per minute at the mouth of the canyon 

 and registering a temperature of 50°. 



Wood River flows first in a southeasterly direction, until it gets within 

 4 or 5 miles of the Platte, when it takes a northwesterly course, follow- 

 ing alongside the latter river until it joins it about 10 miles east of 

 Grand Island. We fished it at Grand Island, where it was not more 

 than 15 feet wide, the water muddy, and standing principally in holes. 

 The banks were lined with small trees. The fishes taken were 

 Hybognathus nuchale evansi, Notropis lutrensis, Notropis blennius, Catos- 

 tomus commersonii, and Carpiodes carpio. 



Middle Loup River rises in Cherry County, in northwestern Nebraska, 

 and joins the South Loup about the center of the State. We examined 

 it at Dunning, where it was 200 to 250 feet wide, averaged inches 

 deep, and had a current of 2 feet per second, thus discharging 112,500 

 gallons per minute. The bottom was sandy and the water clear, with 

 a temperature of 05°. From it we took Platygobio gracilis, Hybopsis 

 aestivalis, Bhinichthys cataractce dulcis, Notropis lutrensis, Noturus flavu&, 

 Hybognathus nuchale evansi, Fundulus sciadicus, Notropis blennius, and 

 Carpiodes carpio. The country about Dunning is prairie with but a 

 few small bushes along the banks of the river. 



Dismal River, a tributary which joins the Middle Loup at Dunning, 

 was also examined. It is 100 feet wide, averages 10 inches deep, and 

 has a current of 2 feet per second, thus discharging 75,000 gallons per 

 minute. Like the Loup River, the water was clear and the bottom 

 sandy. In two or three shallow ponds near by, containing much Lemna 

 and other aquatic vegetation, we found the green sunlish (Aponwtis 

 cyanellus). This was the farthest west in central Nebraska that we 

 took sunfish. From the ponds and river we took, also, Pimephales 

 t promelas, Notropis lutrensis, Catostomus commersonii, and Fundulus 

 sciadicus. The temperature of the water was 66°. 



South Loup and the mouth of Mud Creel: were examined, October 22 

 and August 10, at Ravenna, where they join. The South Loup River 

 here is 150 feet wide, but the water at the times of our visits was very 

 shallow and flowed in several channels over the sandy bottom. Mud 

 Creek is a very sluggish stream, being 40 to 60 feet wide and from 2 to
