44 REPORT OF THE FISH AND GAME COMMISSION. 
together with rights to the water supply, electric current, ete., which 
may be required in connection with the operation of the hatchery gratis 
upon our agreement to operate the station each season. They have also 
gone to considerable expense in repairing and improving the road lead- 
ing to the hatchery. We have, therefore, repaired the clectric power 
line, which was in very bad condition, and have made arrangements to 
repaint the hatchery troughs and make other certain minor repairs after 
the fish have been distributed this summer. 
Brookdale Hatchery. We have made arrangements with the Moun- 
tain Light and Power Company for an adequate supply of water for the 
operation of Brookdale Hatchery during the summer months. Unless 
the extreme drought should cause the streams in that region to entirely 
dry up, a sufficient supply of water to keep the fish alive in the ponds 
is now assured. No improvements nor expensive repairs are at present 
required at Brookdale Hatchery. 
Scott Creek Station. Scott Creek Station has been operated on the 
same plan during the past two seasons as in previous years, and is well 
equipped for carrying on the work without any improvements being 
made. Each season a sufficient supply of steelhead trout fry are planted 
in the ereek to keep up the supply of spawn fish. 
Wawona Hatchery. At a cost of $550 the Wawona Hatchery was 
entirely rebuilt during the spring of 1918. Considerable trouble was 
experienced during the season with the flume furnishing the water for 
the hatchery, and before operations are commenced next spring a new _ 
flume will have to be built. The old one has been in use for a number 
of years and is in very bad shape. 
Yosemite Valley Hatchery. With the increased number of tourists 
visiting the Yosemite National Park, it is essential that the streams and 
lakes of the valley be kept well stocked with trout fry. The only logical 
method of taking care of the requirements of this section is by the 
erection and operation of a suitable hatchery within the valley. A com- 
plete survey of the valley was made in October, 1917, and conditions 
were found to be most favorable for the establishment of a fine hatchery 
near Happy Isles. Accordingly, an application for a lease of the site 
selected as being most favorable for our requirements was made to the 
Department of the Interior through Mr, Washington Lewis, superin- 
tendent of the Park Service, who had assisted in our survey. The mat- 
ter was taken up with Hon, Alex T. Vogelsang, first assistant secretary 
of the Department of the Interior, Washington, D. C., whose interest in 
fisheultural work is known throughout the country, he having at one 
time been president of the California Fish and Game Commission. <A 
satisfactory lease was obtained in due time, and we have ‘since been 
engaged in preparing plans and estimates of the proposed hatchery.
