48 REPORT OF THE FISH AND GAME COMMISSION. 



period of thirty years to cover the land necessary for the establish- 

 ment of a permanent hatchery, together with a right to an adequate 

 supply of water. Considerable difficulty in obtaining a lease which 

 would satisfactorily safeguard the interests of the Commission was 

 experienced and the matter dragged along until so late in the spring 

 of 1920 that there was not time to sufficiently complete a permanent 

 building in order to operate this season. The matter was therefore 

 held in abeyance and operations for this season were carried ou in the 

 temporary quarters. 



This hatchery received 300,000 rainbow eggs and the resulting fry 

 will be distributed in the waters of that section as soon as they have 

 attained the proper size. As soon as possible after the fry have been dis- 

 tributed, construction of the permanent hatchery will commence. 



FISHWAYS AND SCREENS. 

 Fishways. 



The work of our fishway inspection service, has been retarded some- 

 what by the prevailing drought of the last few years, but in spite of 

 this and other obstacles, remarkable progress has been made. As a 

 result of several improvements on the types of fishways made by our 

 surveyor, all the fishways installed under the plans made and ap- 

 proved by this Department have proved more efficient and practicable. 

 Some of the old fishways installed several years ago have been im- 

 proved now, so that the fish have no trouble in passing them. 



The fishway over the Folsom Dam that has been a source of trouble 

 for many years, because it was not built according to the plan de- 

 signed, has been remodeled, and is now in good order. The steelhead 

 trout that ascended the American River this spring had no trouble in 

 jjassing this dam. Several other important fishways have been im- 

 proved during the last two years in addition to surveys for eighty-two 

 fishways located as follows :
