REPORT OF THE FISH AND: GAME COMMISSION. 21 
The Rae Lakes Egg-Collecting Station, located in the Sierras in 
Fresno County, at an elevation of 10,500 feet, was first operated in the 
summer of 1917, and produced 365,000 rainbow eggs, which were trans- 
ported by pack train through the Oak Creek Pass to Mount Whitney 
Hatchery. 
The extensive improvements in the system of operation of the egg- 
collecting stations at Bogus and Camp ereeks on the Klamath River, 
resulted in an increased production of eggs of the rainbow trout. In 
the spring of 1917, in excess of three million eggs were taken and were 
shipped to Mount Shasta Hatchery to be ‘‘eyed.’’ The take of eggs 
during the spring of 1918 was only a little over two million, but this 
was due to the extreme drought which affected our operations through- 
out the entire state. 
The Almanor Hatchery, which had been established in the spring of 
1916 was again operated in 1917 and 1918, and while the number of 
rainbow eggs secured did not meet with our expectations, the take was 
sufficient to justify the expense of operation. The failure to obtain the 
number of eggs which we had anticipated taking was not due to any 
scarcity of large rainbow trout in the north fork of the Feather River, 
but was due to the fact that an average of nearly 600 second feet of 
water was run through the spillway of Lake Almanor by the Great 
Western Power Company almost continuously during the spawning 
seasons; the volume of water passing through our fish racks was such 
that it was impossible for the spawning fish to ascend the streams. In 
i918, owing to the extreme drought and the adverse water pressure 
conditions, only 260,000 eggs were taken.

The Domingo Springs Hatchery which was opened for operation in 
the spring of 1917 promises to be a valuable rainbow egg-collecting 
station. During the first year, over 800,000 eggs were collected. As 
noted above, 126,000 were distributed locally, and shipments of ‘‘eyed”’ 
egos were made to Mount Shasta and Fort Seward Hatcheries. During
