At Wichita, Kan., a modified form of this fishway was put in over 

 or rather around a dam that was built across the little Arkansas. 



Mr. Wells, City Engineer of Wichita, and myself figured out a plan 

 of having a fishway that would start right up close to the dam, so that 

 the water would really fall over it and on it. The fishway started close 

 to the dam and went north until it got past the abutment ; then h 

 turned and went west behind the abutment, and reached the water sev- 

 eral feet above the abutment. Of course a trench was dug behind 

 the abutment, and when the fishway, which was built of steel, was 

 finished, that part behind the abutment was covered with earth. In 

 the building of such a fishway some of the rules for building such 

 structures were violated. In a way it was an experiment. Mr. Wells 

 watched this fishway last spring during May and June, as many 

 people had grave doubts about the thing "working." The fact is that 

 both the engineer and myself had doubts. However, Mr. Wells reported 

 to me that the fishway was a great success. Many fish went up, espe- 

 cially catfish. The exact number and varieties that go up during a 

 given length of time we hope to be able to report at some future meet- 

 ing. However, the fish went up in such numbers that it was necessary 

 to protect the end of the fishway from poachers at night. It was dis- 

 covered that certain persons were stealing the fish that came up 

 through the fishway. 



C. K. Cranston, Oregon : What were the species ? 



Professor Dyche: Many catfish, both bullheads and channel catfish 

 and a good many scale fish, but I could not be sure of the species 

 from the description given. 



I studied the Cail fishway and others, but it costs a good deal of 

 money to build them. The fishway we have planned is not expensive. 

 We hope in the future to determine its efficiency for different streams 

 and for dams of different heights. 



In Arkansas City, Kan., a fishway has been built following plans 

 published in the proceedings. It has a straight run from the river 

 below the dam to the water above. It is on the south side of the 

 river and passes up along the side of the abutment. This entire struc- 

 ture is built of cement : it is as solid as stone. I was told by fishermen 

 that fish went up this fishway. 1 went to see for myself, but it was in 

 July and about noon time. I saw no fish in the fishway. Another year 

 may furnish some definite information, when we hope to have capable 

 men in charge of these fishways. 



Mr. Cranston : How did you meet the difficulty of the varying 

 height of the crest of the dam caused by these steel sheathings you 

 described over the Wichita dam? 



Professor Dyche: The fishway was built underground, starting 

 below the dam and passing around behind the abutment and reaching 

 the water above the dam. 



Mr. Cranston: So that in the high stage of the stream the fish 

 would enter the upper stream well below the surface?
