REPORT OF COMMISSIONER OF FISH AND FISHERIES. 47 



Brood stock and fry on hand June 30, ISDo. 



During the year the station grounds were extended and inclosed by 

 a fence; two ponds, 15 by CO feet, were constructed; a dam 5 feet high 

 and 20 feet h)ng was erected iu Hospital Creek, and a flume 3,060 feet 

 in length was constructed, which gives the station an independent 

 water supply from Hospital Creek. At the substation a new hatchery, 

 18 by 42 feet, with a iinished room for the keeper, 12 by 18 feet, and 

 porch full length, storeroom, etc.. was constructed. The large ponds 

 were also subdivided. 



KORBEL. 



The station was closed from July 1 to September 15. On the IGth 

 work was begun procuring timbers for the construction of a dam, to 

 consist of log piers and stringers for the placing of the racks. Three 

 triangular piers and two abutments, G feet in height, were erected, the 

 largest pier having a base of 10 feet on the sides and 10 feet in rear, the 

 two center spans being 40 feet wide, and the shore spans 30 feet. These 

 structures were filled with loose rock, faced on the sides with rough 

 material, and reinforced all round by a revetment of loose rock 2 feet 

 in height. Every precaution was taken in order to make the structure 

 permanent. 



The water being low in October and November, no salmon reached 

 the station, although great numbers were taken at the mouth of the 

 river. On November 26 the first rain came, and early in December 

 Chinook and silver salmon became very plentiful. During December 7 

 and 8 the water rose rapidly, making a breach under the dam in the 

 deepest part of the current 18 feet wide and nearly 10 feet deep, and 

 letting down one side of the largest pier. A temporary dam of wire 

 netting was put iu as soon as the water subsided sufficiently, the breach 

 was repaired by inserting bags of sand, and the pier carried up by 

 means of timbers and rock. These repairs were completed on the 29th. 

 In February the water again rose so high that the whole structure had 

 to be dismantled, causing much loss of time. During March the water 

 became so low that the fishing had to be done in the main channel of 

 Mad River, 2 miles distant from the station. 



Fishing ceased May 1 and spawn-taking on May 10. Eggs were 

 taken during the season as follows: Chinook and silver salmon (from 

 180 females), 471,500; steelhead trout (from 105 females), 594,000.
