 rather liiiih they were released in Trinity River. They were about 4

Jligh water in Trinity l{i\er prevented the establislmient of tlie i)ro- 

 posed barrier dam in advance of the u])ward movement of the spring- 

 run of salmon, conse(pieiitly no eggs were derived from this source. 



1890-91. 



Dams and traps for stopping and capturing the salmon and trout 

 were constru<5ted both in the Trinity and Eedwood rivers. On the 

 latter stream at Kedwoo<l, a point 13 miles distant from Fort (Taston, 

 an auxiliary station was established. 



The collecting of the eggs of the quinnat and steellirad salmon was 

 begun in November, IH^'i), and continued three months. A dry season 

 caused low Avater in the streams, and l)ut a comparatively small num- 

 ber of fish ascended to the usual spawning-grounds. At Fort Gaston 

 there were secured 45,000 eggs, producing 10,000 fry, 80,000 of which 

 were liberated in Supply Creek, a tributary of Trinity l\iver, and 10.000 

 retained for rearing. These latter were liberated subsequent to June 

 '50, 1801. At tlm auxiliary station at EcihAood ;>0,()()0 salmon eggs Avere 

 collected, and iirodm^ed about 25,000 fiy, Avhieh, at the age of 1 mouth, 

 were released in Minor Creek, a tributary of Ivedwood River, where 

 they remained in schools for some weeks. 



During the development of the eggs the teniperature of the water 

 was.'?8'^ to 45°, andth(^ period of incubation fifty-seven days. 



Theie were three new learing ponds constructed. In one of these 

 about 200 breeding rainbow trout were held till after June oO, 1801. 



A water su])])ly independent of tliat of the military reservation was 

 obtained by nH'aus<»f a trench which was constructed along the moun 

 tain side over a distance of about a lourtli of a mile.
