92 CALIFORNIA FISH AND GAME. 



Creek, a tributary of Feather River. The station is located near Johns- 

 ville, in Plumas County. The operations last season were successful, 

 and accordingly i)lans were made for the establishment of a permanent 

 hatchery at this site. 



CLEAR CREEK HATCHERY, 



The Clear Creek Hatchery and Egg-eolleeting Station was established 

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

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

 tributary of the Hamilton branch of the Feather River, and a large 

 portion of the spawning rainbow trout that ascend the Hamilton 

 Branch of the Feather River enter this stream. As the source of Clear 

 Creek is in a large spring, the water is pure and cold. The Red River 

 Lumber Company furnished the site and material for the Clear Creek 

 Hatchery, and the Fish and Game Commission furnished the labor for 

 construction. Operations at this hatchery have been very satisfactory. 



FALL CREEK HATCHERY. 



In January, 1913, the California-Oregon Power Company began the 

 construction of a concrete dam in the Klamath River two and a half 

 miles above the mouth of Fall Creek in Siskij^ou County. This dam, 

 110 feet high, has required a great deal of study on the part of the 

 flshcultural department. The great problem involved was whether an 

 et!icieut fishway could be constructed on such a dam, and if such a fish- 

 way were constructed, what would be the benefit derived from such an 

 undertaking. The principal run of fish on the Klamath River in the 

 region of the Copco dam is trout and salmon. The Federal Bureau of 

 Fisheries has operated a salmon egg-collecting station on the river 

 below the dam and have for the la.st eight years prevented the salmon 

 from ascending the river above the racks at Hornbrook. This is neces- 

 sary in order that the supply of salmon may be maintained in the 

 Klamath River. If the racks were removed and the salmon allowed to 

 ascend the river, and a fishway constructed that would allow the pas- 

 sage of the breeding salmon al)ove the dam, the resulting fry would have 

 to return to the ocean and on their downward journey would be destroyed 

 by the power wheels of the hydroelectric plant that takes the water 

 from the dam. Therefore the construction of a fishway for the passage 

 of salmon above the Copco dam was not feasible. Accordingly, in 

 compliance with the law, the Fall Creek Hatchery was constructed and 

 paid for by the California-Oregon Power Company in lieu of construct- 

 ing a fish ladder over the Copco dam in the Klamath River. 



Under the provisions of the law passed by the legislature, whenever 

 a dam or other obstruction is placed in a river or stream that, in the 

 judgment of the Fish and Game Commission, is too high for the suc- 

 cessful operation of a fishway, or for other reasons it is deemed best to 

 establish a hatchery below the dam for the propagation of any species 

 of fi.sh that may be interfered with by the construction of the dam, the 

 owners of the dam must construct and equip a liatchery for the pur- 

 pose of propagating fish for the river and turn the hatchery over to 

 the state for operation.
