METCALF CREEK TRAP. 



This station is located on the shore of Bear Lake. During a season 



of normal rainfall this trap produces a fair number of eggs; but the 



take for the last two seasons was considerably less than in former years, 



owing to the small amount of water in the stream as well as to the 



blocking up of the mouth of the creek with sand bars. Considerable 



improvements caij be made there to better the conditions at this small 



auxiliarj^ station. 



WAWONA HATCHERY. 



Waw^ona Hatchery has been successfully operated during the last two 

 seasons with the same good results as in former years. The total output 

 of this hatchery during tlie biennial period of 1922-1924 was 389,300 

 steelhead and 498,200 rainbow trout fry. This station should be main- 

 tained as it is located on a site where it is easy to get the fry to the 

 lakes and streams south and east of the Yosemite Valley. A cabin for 

 the foreman should be built on the hatchery grounds this coming spring 

 so that better protection could be given the plant during the time when 

 the building is closed. Under the present arrangement, the foreman 

 lives in a tent and the accommodations are not very good. 



KAWEAH HATCHERY, 



Kaweah Hatchery has been operated for the last five years under a 

 tent and it is time that a permanent building be erected either on the 

 present site or on a site in the Sequoia or General Grant National Parks. 

 The improved roads, constructed since this hatchery site was first 

 selected, cause us to believe that a more favorable site may be found in 

 the Sequoia or General Grant National Parks ; and a survey will be 

 made in the near future to determine whether a better site may be 

 selected. If the same can be found, recommendations will be made for 

 the erection of a permanent hatchery in this section. If a new site can 

 not be procured that affords better opportunities than the present site, 

 we recommend that a permanent building be built on the present site. 

 In the spring of 1923, to accommodate a larger output of fry, ten 

 extra hatching troughs were installed in this hatchery, making twenty 

 in all. This is not large enough to supply the district that is making 

 requests for fish for Sequoia and General Grant National Parks, Tulare 

 f*ounty, Tulare River, and lakes in the southern high Sierras. A 

 hatchery witli a capacity of at least sixty troughs should be built for 

 this section. The total number of fry distributed from this station was 

 as follows : In 1922, 435,000 ; and in 1923, 440,000. 



BIOLOGICAL SURVEY OF LAKES AND STREAMS. 



In an effort to improve the methods of stocking the barren lakes and 

 streams of the high Sierra range, we recommend that a biological surve.y 

 of the streams and lakes of the Sierra rauge be )nade and plans to stock 

 this entire region be carried out as rai)idly as money and fish can be had 

 for this purpose. The region of the high Sierra range contains many 

 thousands of lakes and streams that are barren of fish life. This region 

 should be stocked with sj)ecies of fish best adapted to the physical con- 

 ditions of the streams and lakes as regards temperature, altitude and 

 aquatic insect life. Many of the higher lakes of this region, particu-
