10 PISH AND GAME COMMISSION. 



aiul saves the expense of keeping and hiring teams. Owing to a lack 

 of water supply during the late summer, the Almanor Hatchery was 

 abandoned in the fall of 1920. The Johnsville Hatchery on the Feather 

 River A\-as moved to a new site because of the deep snows which hindered 

 operations in its former location. Scott Creek Egg Collecting Station, 

 \\ hich heretofore has belonged to Santa Cruz County, was purchased by 

 the Commission in 1920. This was in line with the policy to own and 

 maintain all of the hatcheries rather than repair and improve leased 

 proi)erty. Two hatcheries, the Ukiah Hatchery and the Brookdale 

 Ilatchery, are still under lease, respectively, from the city of Ukiah 

 and the County of Santa Cruz. 



TROUT. 



The success of the pond system is evident when it is known that 

 breeders from hatchery ponds furnished 18,000,000 trout eggs during 

 the last biennial period. 



One means of augmenting this system would be the setting aside of an 

 area above the Cape Horn Dam on the south Eel River, as a fish 

 preserve to be used as a source of supply for trout eggs. The lake 

 impounded by this dam is known as Tjake Pillsbury and several tribu- 

 tary streams would fui'nisli successful breeding places for trout. 



Continued efil:'orts are being made to increase the output of the 

 Tahoe black-spotted trout. A new egg-collecting station has been estab- 

 lished on the upper Truckee, which will make use of trout, many of 

 which would eventually lose their lives on returning to the lake because 

 of flooding operations carried on by the ranchers. 



Expei'ience has shown the golden trout to be a delicate fish and much 

 sul)ject to disease. As a consetjuence, the hatching of this species has 

 been discontinued pending rejjorts as to the success attained in stocking 

 Sierran streams. 



SALMON. 



Klamath River egg-collecting stations furnish most of tlie salmon 

 eggs for tlie hatcheries. Operations of the United States Bureau of 

 Fislieries at theii- station on the Sacramento River were hindered by 

 lack of water and l)y the fact that spawning salmon did not succeed in 

 passing the Redding Dam and consequently spawning operations could 

 iioi ])e can-ied on at the Baird Station. Low water was largely respon- 

 sible for the failure of the attempt to secure additional eggs on the 

 south fork of the Eel River at ■l>i'aiise()nil). 



FISHWAYS AND SCREENS. 



During llie pasi 1\vo _\-ears forty-one inspections of and twenty-eight 

 suj'veys for iisliways were imide. Surveys to tlie number of 187 wei'c 

 made for screens. Splendid progress has l)een made in the enforce- 



iiieiit of llic sefeen and Jaddei- laws. 



RECOMMENDATIONS.

1. 'J'he e.stabJishment of more hatcheries and egg-collecting stations to
