THIRTY-SIXTH BIENNIAL REPORT 19 



made to the hatchery building and living quarters and if the Division 

 is to avoid expending a rather large sum on rehabilitating this unsatis- 

 factory station it will be necessary to obtain a new site and start experi- 

 mental work this year. It is, therefore, recommended that a number 

 of sites along the South Fork of the Eel River be investigated this 

 season and active steps be taken to set up one or more experimental 

 stations for operation next fall. One of the most promising sites is 

 near Dj^erville on the South Fork and water could be obtained from 

 Canoe Creek which lies within one of the State parks. It is hoped 

 that arrangements can be made for a hatchery site on land which is 

 already owned by the State. This prospective hatchery site is indicated 

 as No. 28 on the map and would replace Fort Seward which is No. 4. 



It will be noted from the map that from this previously mentioned 

 station (No. 28) south to San Francisco no hatcheries are now in oper- 

 ation since the Cold Creek Hatchery (No. 24) near Ukiah was destroyed 

 in 1938. Although the streams in these counties — Mendocino, Lake, 

 Sonoma, Napa and Marin are, for the most part, small, they are very 

 heavily fished due to their close proximity to the metropolitan areas 

 around the bay. A supply of spring water is available in the south 

 end of Lake County and it is recommended that negotiations be under- 

 taken for a lease and option so that this water could be tried out in an 

 experimental way for the development of rearing ponds. This would 

 make it possible for us to supply fish of somewhat larger size for cer- 

 tain streams and lakes in Marin, Napa and Lake counties. 



It has been apparent for some time that there is great need for 

 a supply of catchable sized fish for planting in the southern San 

 Joaquin-Sierra region. Included in this area are the streams from the 

 San Joaquin south to and including the Kern. It has now been 

 arranged for the Bureau of Fish Conservation to take over the opera- 

 tion of the sportmen's ponds at Kernville, which is shown as No. 31 

 on the map. These ponds will furnish an ample supply of fish of 

 some size for all of the waters of the lower Kern and its tributaries 

 which can be reached at reasonable transportation costs. There still 

 remain a number of heavily fished streams and areas which are under 

 prospective development in the counties from Tulare County north 

 through Fresno and Madera. The streams included are the Tule River, 

 the Kaweah River, Kings River and the San Joaquin. At the present 

 time we have one large hatchery, No. 3, located on the Kings River, 

 two small seasonal or summer rearing stations, No. 8, Madera Hatch- 

 ery, and No. 2, Huntington Lake Hatchery. The fourth hatchery for 

 the area is No. 22, Kaweah, which is of medium size and like all of 

 this group mentioned, is designed solely for the rearing of small fish 

 for early planting. The development of the Sequoia and Kings River 

 park areas and the growth of population in the southern San Joaquin 

 make it advisable for us to develop as rapidly as i)ossible facilities for 

 rearing fish of larger size. In this entire area there is practically no 

 spring water of consequence. Such springs as exist are small in volume, 

 cold in temperature and located at rather high elevations. With a 

 view to possible use of well water of .suitable temperature, some investi- 

 gation has already been made. At the present time we have found 

 one well near Visalia which has a temperature of f)? degrees and so 

 located that water pumped therefrom could advantageously be used
