REPORT OF THE PISir AND GAME COMMISSION. 41 



During the two years 850,000 rainbow and steelhead trout fry were 

 (lisfrilmtcd in the streams ami lakes in lliis disti-ict from Domingo 

 Springs Hatchery. A total of 2,200,000 rainbow trout eggs was col- 

 lected at this station during the two seasons. 



Each season a consignment of steelliead trout eggs is shipped to 

 Domingo Springs Hatchery and the resulting fry are planted in llic 

 high Sierran lakes of that region which are suitable for this variety. 

 The steelhead trout have thrived rcmarka1)ly well in the lakes of this 

 section and afford some of the finest fishing in the state.

CLEAR CREEK HATCHERY. 

 The Clear Creek Hatchery and Egg-collecting Station was established 

 in the fall of 1918, on the creek that bears its name, one and one-half 

 miles from the town of Wostwood, Lassen County. Clear Creek is a 

 tributary of the Hamilton Branch of the Feather River. Before the 

 construction of the dam forming Lake Almanor, it flowed into the val- 

 ley known as Big Meadows, and united its waters with those of the 

 North Fork of tlie Feather River, which entered the Big Meadows 

 l)asin from the north. Hamilton Branch flows into the basin from the 

 east. The TTnmilton Branch has a run of rainbow trout that ascend 

 the stream to spawn from Lake Almanor. Clear Creek being one of the 

 principal tributaries of the Hamilton Brancli a good portion of the 

 spawners enter this creek. The distance from tlic Clear Creek Station 

 to the Domingo Springs Station is approximately twenty miles. Clear 

 Creek has its source in a large spring and the water is pure and cold as 

 all the waters arc tliat rise in a lava formation.
