348 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



Lake and not so much vegetation around the shores. We made several 

 hauls in it and secured nothing but Apomoti.s cyanellus, all young, many 

 of them but one-half inch long. Eight ear]) were planted in this lake 

 at the same time the 2,000 were put in Carp Lake, but they have never 

 been seen since. A few sunfish and a few bullheads were planted in 

 this lake at the time those were put in Carp Lake. Both lakes abound 

 in fish food, and the conditions are very favorable for the black bass. 

 The water in both lakes is quite pure and the temperature at the time 

 of our visit was 70°. 



A little lake of about 20 acres, north of Carp Lake, was visited, but no 

 fish were found. The water was not more than 1 foot deep and was 

 very warm. In one haul of the seine we took a large number of tadpoles 

 and about 150 larval salamanders. 



In addition to the lakes mentioned, there are other small ponds and 

 marshes throughout the region, but all are shallow and contain no fish. 



Elkhorn River rises in the central part of Rock County, in northern 

 Nebraska, flows southeast and finally south, aud empties into Platte 

 Eiver about 30 miles above its mouth. We examined it at Ewing and 

 at Norfolk, Nebr. At Ewing the stream was about 100 feet wide and G 

 inches to 5 feet deep, averaging 18 inches, and the current was moderate. 

 The bottom was sandy in most places, but occasionally there was a 

 bunch of aquatic vegetation, in which we found sunfish (Apomotis cya- 

 nellus) and black bass (Micropterus salmoides). We also took two spe- 

 cies of suckers, a catfish, two darters, and several species of minnows. 

 Near the river are some old bayous that are probably connected with 

 the river during high water, but at the time of our visit were isolated. 

 These contain thousands of young black bass, most of them about one- 

 fourth inch long. 



Elkhorn Kiver, 2 miles southeast of Norfolk Junction, is 150 feet wide, 

 averages 2 feet in depth, and has a swift current. The bottom is sandy 

 and trees line the south bank. Among the fish taken here were the 

 pickerel (Lucius lucius), large-mouthed black bass, redhorse sucker, a 

 darter, aud a number of minnows. 



Near the river are some bayous that furnish excellent fishing for the 

 people of Norfolk, the principal fish being black bass and sunfish. 

 There arc two of these bayous located in a nicely wooded grove. The 

 water was quiet and in the shallow places completely matted with 

 aquatic vegetation. From the banks the sunfish could be seeu quietly 

 swimming around looking for food, while farther along, perhaps, num- 

 erous fish were jumping out of the water to catch the unwary insects 

 that had ventured too near the surface. Many frogs were seen along 

 the banks and the aquatic vegetation was well loaded with numerous 

 forms of animal life. One noticeable fact was the scarcity of minnows, 

 yet this is not remarkable when we consider the abundance of bass. 



South Fork of Elkhorn River. — The tributary of Elkhorn Eiver near- 

 est its head, which we examined, was the south fork of the Elkhorn 

 at Ewing, Nebr. The stream was 30 feet wide, 1 foot deep, current
