NORTH CREEK EGG COLLECTING STATION. 



This station has ])eeii opeiated during the last two seasons as formei-ly. 

 The run of trout during 1 020-1 !)21 in North Creek averaged about the 

 same as during the two former season-;. There w^ere 4,000,000 trout eggs 

 collected during the two seasons covered by this report, 1,150,000 eggs 

 were hatched and the resulting fry distributed as soon as they were 

 swinuning up well, wliich is the I)etter way to plant fry in a lake such 

 as Bear T^ake where the water is shallow along the shores and where 

 the large trout do not feed. There is an abundance of insects in Bear 

 Lake so that the trout do not want for natural food. The fact that Bear 

 Lake still att'oi-ds good fishing for the anglers who visit it each season, 

 is proof that this system of planting in Bear Lake is producing good 

 results, as there are no natural spawning streams flowing into the lake 

 in which the trout can spawn. The traps and tanks at North Creek 

 Station w^ere damaged by the flood water that came down the creek dur- 

 ing December, 1921, as were all the traps at our egg-collecting stations 

 on Bear Lake. These Avere temporarily repaired for the operations 

 during the spring of 1922. Permanent traps with concrete foundations 

 should be built as soon as the funds are available for this work. It will 

 be more economical in the end than to be repairing damages caused by 

 high water on traps that are not built on firm foundations. 



METCALF CREEK TRAP. 



This small station is an auxiliary of the North Creek Egg-Colleding 

 Station. The same conditions prevailed at this place as are described 

 for the North Creek Station. The trap was washed out during 

 December, 1921, and temporary repairs made. This trap should have 

 a concrete foundation and a dififerent type of trap installed. 



GROUT CREEK TRAP. 



Likewise, the trap located on Grout .Creek, (me of the streams flowing 

 into Bear Lake was washed out by the flood of December. 1921, and car- 

 ried a quarter of a mile down the stream and deposited on the sand 

 covered flat and there it was left when the flood waters receded. This 

 trap Avas not used this season as the expense was too great to repair it 

 or to build a new one. 



WAWONA HATCHERY. 

 This hatchery has been operated during the last two seasons, with good 

 results. During the fall of 1920, the troughs, foundations and tank, 

 were renewed and repaired where it Avas found necessary. A bridge was 

 constructed over the IMerced River opposite the hatchery so that sup- 

 plies could be delivered to the hatchery and the fish cans taken across
