316 FIFTEENTH ANNUAL REPORT OF THE 



The fish have been maintained in a healthy condition. No disease 

 has affected them, owing largely to the work done two years ago in dredging 

 the bed of the creek just above the hatchery. This work should be continued 

 in the same manner up to and including the head of the stream. The plank 

 retaining wall at the head of the creek is in bad condition. A concrete 

 retaining wall should be built next summer all around the springs, which 

 should be thoroughly cleaned out in order to improve the flow of water 

 materially at low water time. 



We were disappointed in getting lake trout eggs from the upper lakes 

 last year, which cut us short in our output of lake trout. 



The hatching of the lake herring was very successful. We did not 

 collect a great many eggs as the boats were all engaged before our men 

 reached Dunkirk, but we hope to do better this year. Funds were pro- 

 vided to do necessary repairs which are not completed, but we are still at 

 work at them and hope to do much more if the weather is favorable. A 

 new dam was placed in the creek instead of the old one, so as to control the 

 water. A cement feed trough was laid from the main creek to the lake 

 trout house. Some of the ponds w T ere built up with concrete from the water 

 line to the top, adding much to their appearance. This should be continued 

 next year, finishing all in the same manner. The old carp pond at the 

 icehouse has been filled up and graded off, making a great improvement to 

 the lawn. Another pond should be filled and graded next year, as it is 

 of no further use. 



If the Commission wishes to increase the output of Caledonia hatchery 

 another house should be built for we are now at full capacity. 



Some repairs at the Guthrie hatchery must be done this year. The 

 troughs have all given out and must be replaced. 



Respectfully submitted, 



Frank Redband.
