REPORT OF BOARD OF FISH AND GAME COMMISSIONERS. 
the new site was decided upon, proper surveys were made and a con¬ 
crete dam 75 feet long was placed in Taylor Creek to divert water into 
an iron pipe line, approximately 900 feet long. This pipe line was put 
underground and only emerges to the surface when the settling tank is 
reached. A building 40 by 70 feet, resting on concrete foundation, was 
then erected. Following the suggestion of Superintendent W. H. Sheb- 
ley of our Sisson Hatchery, a radical departure was made in the arrange¬ 
ment of troughs. Instead of having a head trough on one side or end 
of the building, two head troughs were placed—one on each side of the 
building—permitting an aisle through the center. 
The abundance of water permits each trough to be fed separately, and 
overcomes the disadvantages of having one feed into another—convey¬ 
ing excrement and possible disease into the lower one. The building 
was very solidly constructed, shingled overall, and forty troughs were 
installed, which give a capacity of about three million eggs, as against 
a million in the old hatchery. The total cost of this station complete 
was $3,534.00, which included all the labor and material used in its 
construction. It was paid for out of the fish commission fund. In the 
fall of 1909 a four-room cottage for the men was constructed in the 
enclosure of the hatchery grounds, at a cost of $750.00. This work was 
economically and substantially done. We believe for its purpose a 
more complete hatchery^station can not be found. 
At the Tahoe Station important improvements were also made. The 
foundation under the hatchery, which had done duty for many years, 
was taken out and entirely renewed, new porches added to hatchery and 
superintendent’s cottage, and material ordered for new troughs, floor¬ 
ing, and an iron pipe line, to take the place of the old wooden flumes. 
The latter had been a menace for years, and permitted the escape 
through leakage in various ways of sufficient water to seriously curtail 
the output of the station. By the installation of this iron pipe line 
* 
y/ith laterals and small concrete dams at the various springs, shutting 
off the underflow, we expect to increase the water supply fully one 
third, which will permit of a substantial increase in the hatchery out¬ 
put as the demands justify. 
The average number of cut-throat eggs taken from Taylor Creek for 
several years was about three million, our operations being limited to 
the capacity of the three stations—one and a quarter million to fill 
Tahoe Hatchery, a million for the Tallac Station, six hundred thousand 
to the Glen Alpine, and the remainder being distributed between 
Wawona, Sisson, and Ukiah hatcheries. For the season of 1910 the take 
was the largest ever made, being about 6,150.000 eggs—all taken from 
Taylor Creek. 
This result furnishes an unanswerable argument to the criticism that 
is sometimes made, that the artificial propagation of fish is not a sue-
