Dyche. — One Year's Work at Kansas Hatchery 81 



through the five chains of ponds that make up the main 

 body of the hatchery. 



In other words, there are, all told, ten ten-inch pipes 

 that carry water from Pond No. 1 to the five chains of 

 ponds that make up the pond system of the hatchery. 

 Nearly all ponds in the five chains of ponds are connected 

 with adjacent ponds by two ten-inch pipes and each pond 

 in a chain that extends east is from six to twelve inches 

 lower than the one west of it. This gives a good gravity 

 flow to the water through the system. 



The gates that control the water in the pipes and the 

 wire screen gates that control the fish, are all set in solid 

 cement structures called water transmitters. The new 

 water system seems to work well, though in places the 

 new earth that was not yet compact and had no vegeta- 

 tion to help hold it, washed down and somewhat inter- 

 fered with the wire screen gates in the cement water 

 transmitters. Where the ground was compact, but little 

 trouble was experienced, and after another year or two, 

 when the ground has settled and is covered with vegeta- 

 tion we expect but little, if any, trouble. It will be two 

 or three years before these ponds and embankments can 

 be put in good shape. It takes time for banks to settle 

 and for vegetation to get well set. 



STOCKING THE NEW HATCHERY. 



As spring began to advance, many plans were made 

 for stocking the new fish hatchery. The ponds were 

 new and without any vegetation. About one-third or 

 one-half as many spawners were placed in each pond as 

 would have been placed in them if they had been well 

 supplied with vegetation. " The ponds were stocked in the 

 last part of April and the first part of May. In less than 

 a month after black bass were placed in them, schools of 

 young fish were seen near the shore. Schools of young 

 crappie were seen in June, bull-heads and blue-gills ap- 

 peared in the latter part of July and the first part of 

 August.
