HYDROGRAPHIC DEPARTMENT
In April 1927 Mr. E. C. Eaton, Chief Engineer of the Los Angeles County Flood Control District, created the Hydrographic Deµirtment, with Francis H. Hay as Chief Hydrographer. One of the duties of this department was the collection and compilation of stream flow data in Los Angeles County.
This work has be~n continued throughout the year beginning October 1, 1929 and ending September 30, 1930 ..
Installation of gaging stations throughout the County was continued until at the end of the year the District has constructed and is operating 43 stations. Of these stations, 17 are equipped with AU continuous water stage recorders, 11 with Stevens drum-type, 1 with Stevens continuous, and 14 with Rational drum-type.
The District also operates 12 stations in cooperation with the United States Geological survey, Water Resources Branch, and 2 stations formerly operated by the Pasadena Water Department, making a total of 57 stations equipped with automatic water stage recorders in operationo Sixty-six staff gages have been installed on various streams and washes where the gage heights have been r~ad during storms.
Approximately 2300 stream flow measurements were made at various locations on streams and washes in Los Angeles County during the 1929-1930 secson.
The following automatic recordinf gage stations were established during the yeari
Big Tujunga, West Wash at Ma2:nolia Avenue Big Tujunga, Ea.st Wash at Map.:nolia Avenue Coyote Creek at Pacific Electric RR. bridge near Artesia..
Dume Creek at Roosevelt Highway. Topanga Canyon at Highway Bridge about 2 miles
from ocean.
Station descriptions, lists of measurements, daily gage heights and discharges, monthly discharges, and measurements of percolation for various streams throuf;thout the County for the water year commencing October 1, 1929 and ending September 30, 1930 are i~~cluded in this report.,
