WILL FURNISH "GIANT" POWER
P.P.&L. Company Furnish Power for 200 Ton Sand Shovel

Electric shovels served by Pacific Power will take out 1,000,000 tons of gravel from a Columbia river bar near Avery for the Bonneville dam, according to B.P. Bailey industrial engineer.
Operations on the job of moving the gravel out of the bar to the dam site are now underway, following the completion of two and one-half miles of transmission line from Wishram to serve the Avery plant.
In 16 days, the two and one-half miles of line was surveyed, right-of-way purchased, and the line finished and ready for operation.
Columbia Construction Company, which has the contract for the main spillway dam, will receive its supply of gravel from this plant and its sand from a hill near Bingen. The large gravel bar at Avery, submerged during high water, is more than 30 feet deep. The gravel is clean and can be handled easily.
Work was begun May 8 on the new transmission line, which connects with The Dalles-Goldendale line. G.R. Johnson, chief of the survey crew of four men, conducted the survey, C.O. Bunnell had charge of purchasing right-of-way. A line crew from The Dalles under the supervision of Frank Jahn, foreman, built the line, and the crew from the construction department under the supervision of Lance Read, foreman, built the sub-station at Avery.
Fifty-seven polls from 35 to 45 feet high where required for construction. A bank of three 200-kva transformers were installed at Avery to step down the energy from 11,000 to 2300 volts. And oil circuit breaker was installed on the 2300-volt line to control the load. Total cost of the line was $8500.
Estimated load at the plant will be 250-kw. Most of it will be used for the shovels, which will operate for the next two years.
It is estimated that 500,000 tons of sand will be taken out of the hill at the Bingen by drag lines for the main spillway dam. Work will start on the main dam as soon as the high water subsides.
A steam derrick with large bucket for loading will be used in the loading operations, it was pointed out. The derrick has a 90 foot boom and a 5-yard scoop. The equipment weighs over 200 tons and was formerly employed at the Boulder dam.
