BUREAU OF FISHERIES 329 
Protection of fish runs from engineering developments——The 
establishment, early in the year, of a section on hydraulics within 
the Division of Scientific Inquiry provided for the application of 
biological and engineering skill to fishery problems created by the 
construction of dams, reservoirs, and diversions for the purposes of 
power, irrigation, navigation, and flood control. 
The work of the Hydraulics Section during the first year of its 
existence has been devoted to three general phases of fish protection: 
(1) Supervision of the construction of four large fish screens in 
Federal irrigation canals and the operation of Federal screens already 
constructed; (2) consultative services in connection with fish-salvage 
problems at the Shasta Project on the Sacramento River; and (3) the 
review of Federal water projects from the standpoint of fish pro- 
tection. Advice in connection with fishway and screen problems has 
also been furnished the conservation agencies of several States.
