2012.20.3Description
Small photo of a suction dredge excavating open, unlined canal section of the L.A. Aqueduct. The location is between the aqueduct intake and Independence looking south. Photo 2012.20.8 is likely the same dredge from a different position.
Information from the L.A. Aqueduct Annual Report, 1908, page 19:
"The first twenty one miles is being excavated by means of a hydraulic dredge. The motive power is 110 KW or 147 J4 HP required is furnished by the City's hydro electric power plant No. 1 situated on Division Creek A second dredge heavier and of somewhat larger capacity than the first is being constructed and will be placed in operation south of Independence. From the rate of progress made by Dredge No. 1 it is estimated that each dredge will make an average progress of 3-4 miles per year or that three years will be the total time required to complete the 21 miles. A second power plant to develop 600 KW or 804 HP is now under construction on Division Creek to furnish power for Dredge No. 2."
