SEATTLE (AP) — The Army Corps of Engineers has pumped nearly 400,000 gallons of grout into a leaky abutment at the Howard Hanson Dam on the Green River, southeast of Seattle.
That's the figure given by Mamie Brouwer, program manager at the dam. The corps is hurrying to complete a grout wall within the abutment by Nov. 1 and the start of the winter rainy season.
