340 REPORT OP COMMISSIONER OF FISH AND FISHERIES. 



in great quantities. Water that appeared to be 6 inches deep was 

 found to be 12, the lower part being completely tilled with the fine mud 

 particles. In the mouth of this river we found such species as Leptops 

 olivaris and Polyodon spathula, which had run in from the Missouri. We 

 were told that spoonbill cat as long as 5 feet and buffalo weighing 30 

 pounds or more are often caught here. 



Chadron Creelc is a small stream, some 15 miles long, which empties 

 into White River 3 miles west of Chadron, Nebr. We fished it not far 

 from the mouth, where it was 4 to G feet wide and 2 to 3 feet deep, with 

 a very sluggish current. There was no vegetation along the banks 

 except grass. 



Lone Tree Creel; 20 miles in length, flows from the northwest and 

 empties into White River, near the mouth of Chadron Creek. Near its 

 mouth, where we examined it, the stream was 40 to 50 feet wide and 

 from 4 to 8 feet deep. The banks below the surface of the water were 

 almost perpendicular, and the water so deep that we could do but little 

 seining. The water was muddy and the current very sluggish. AVhile 

 the creek seemed to discharge but little water, the portion examined 

 was a continuous pool. The banks were bare, with the exception of a 

 very few small shrubs and some grass. 



Choteaii CreeJc is a small creek flowing into the Missouri from the 

 north, 15 miles west of Springfield, S. Dak. At the place examined it 

 was 50 feet wide and ranged from 1 to 8 feet deep, but averaging about 



3 feet. The bottom was covered with soft, black mud, 15 inches deep 

 in places, which gave forth large quantities of marsh gas when stirred. 

 The bank on one side was well wooded, some of the trees being quite 

 large. The trees and shrubs noted were ash, Cottonwood, box-elder, 

 oak, elm, willow, sumac, and plum. The temperature of the water at 

 noon June 27 was 73°. 



Much alga3, Potamogeton, and other aquatic plant life were found in 

 the water. We fished the stream in several places and took as many 

 as 10 different species of fishes. Among the valuable fishes were the 

 wall-eyed pike, bullhead, channel cat, black sucker, redhorse sucker, 

 and buffalo. Several other species of less importance were taken. 



Ponca CreeJc rises in the southern part of Tripp County, S. Dak., 

 flows a little southeast, and empties into the Missouri River in the 

 northwestern part of Knox County, Nebr. It is more than 100 miles 

 long, flows through a prairie country, and at its mouth is 41 feet wide, 



4 to 8 feet deep, with a sluggish current and, at the time examined, 

 muddy water. The sluggish current, depth of the water, and its 

 muddiness were in part due to backwater from the Missouri River. 

 Only two species of fish were taken, Hiodon alosoides and Hybognathus 

 nuchale evansi. Temperature of water 72°, air 70°. The banks of the 

 stream were heavily wooded. 



Niobrara River. — The Niobrara River rises in eastern Wyoming, 

 flows east through northern Nebraska, and empties into the Missouri 

 River at the northeastern boundary of Nebraska. At Marsland, the
