The following statement in connection with the recent floods near Edgewick, caused by water leaking through the porous north bank of the Cedar river reservoir, was made yesterday by Councilmen Oliver T. Erickson, W. D. Lane and William Hickman Moore, after a visit to the district:
"Councilmen Erickson, Lane and Moore returned from Cedar lake Sunday night, after spending two days in investigating the conditions existing in the vicinity of the city's new masonry dam and in examining the reports of engineers and other records and data in relation to the sealing of the basin. Okeh [sic] Masonry Dam.
"They found that the masonry dam as constructed by Clark Nettleton, publisher of the Post-Intelligencer, and his associates, and completed in September, 1914, was an excellent piece of work, in as good condition as when constructed and standing as firm as Gibraltar. The dam which is reported to have gone out was a small wooden dam across Boxall creek at Edgewick, near the south fork of the Snoqualmie river, about four miles in northerly or northeasterly direciton from the city's new masonry dam. This small wooden dam was used by the North Bend Lumber Company for the purpose of impounding water in which to store saw logs and shingle bolts. What is alleged to have been the break in the north bank of the Cedar river basin is more than a mile north of new masonry dam and is well over the northerly slope of what is known as the north bank. They found no evidence that this break was due in any way to the construction of the new masonry dam or the impounding of the waters back of it.
"Engineers Muholland and R. H. Thomson had reported to the city council in writing recommending that an effort should be made to seal the basin by sluicing down the banks and impregnating the same with clay, which method was pursued by Superintendent of Water Youngs in the work done theron. Before Mr. Youngs began the sealing operations last summer the seepage from the basin was in excess of five second feet per acre; the seepage now is less than one second foot per acre and is steadily decreasing, although only about one-fifth of the basin has had the sluicing treatment. The water back of the new masonry dam was sixty-five feet deep on Sunday, and has been from sixty-five to seventy feet deep for over a month. Pipe Line More Effective.
"No. 3 pipe line, which is 5 feet 8 inches in diameter, has been connected with the new masonry dam for a month and is 15 per cent. more effective than when connected with the old wooden dam at the upper end of the basin. No. 1 pipe line, which is 4 feet in diameter, will be put in operation today, and with both of the lines connected with and supplied from the new masonry dam, it will be possible to develop between 11,000 and 12,000 kilowatts at the present Cedar falls plant, which will increase the plant's revenues at least $400 per day as at present equipped.
"These councilmen are of the opinion that the new masonry dam will accomplish the purpose for which it was constructed and, if so, it will be necessary to construct an additional pipe line and install an additional generator in order to utilize its full commercial value."
