THIRTY-FIRST BIENNIAL REPORT 51 



PIT RIVER EGG-COLLECTING STATION 



The construction of an egg-collecting station at Hagen Flat on Pit 

 River by the Pacific Gas and Electric Company in lieu of a fishway 

 over their high dams in the Pit River has been decided on and a site 

 has been selected, survey made, and all preparations are now under 

 way to install this station during the coming summer and fall. We 

 waited several years before making a request of the power company 

 to build this station, as it was not certain whether enough salmon would 

 ascend the Pit River to justify the expense of establishing a salmon 

 egg-collecting station. After a number of surveys on Pit River during 

 the salmon spawning season, we discovered that a sufficient number of 

 salmon ascended the stream to justify us in our request that the com- 

 pany construct racks, traps, and an egg-collecting station on a site 

 selected below Power House No. 4 of the Pacific Gas and Electric Com- 

 pany. This station, do doubt, will enable us to collect a number of 

 trout eggs each spring for the Burney Creek Hatchery. We hope to 

 see this station installed and ready for the trout run this coming 

 spring and in readiness for the salmon run in the fall of 1931.

During the months of September and October of 1929, the installa- 

 tion of a new water system to furnish water for the houses was finished. 

 Owing to the opening of the road between Powers Creek and Alder- 

 point and the consequent use of the Powers Creek watershed as a picnic 

 and outing ground, and also to the constant fouling of the creek water 

 by cattle and campers, it became necessary to find and develop a new 

 source of domestic water. A spring was opened up and developed at a 

 point about 1500 feet above the houses in the Fort Seward Creek water- 

 shed. This spring was enclosed in a concrete box from which the water 

 was piped to a 3000-gallon redwood tank. From the tank the pipe was 

 laid down the canyon to the dwellings. The pipe used is l-|-inch and 

 as this pipe is one-half inch larger than the pipe used in the old system 

 and the head is much greater, we now have a fine supply of good pure 

 water that can not be contaminated and which is delivered at heavy 

 pressure. So far the supply has been more than sufficient for all needs, 

 including irrigation of the grounds at the dwelling.
