The latest on the work to clean out Albany's Santiam Canal from the Union Pacific tracks to Seventh Avenue, a $384,000 project being done by Richard Phillips Marine Inc. of Boring under contract with the city: This is what it looked like just downstream from Ninth Avenue on Thursday night. Most of the flow goes through the 48-inch-diameter pipeline, and a temporary dam keeps the water from surging back into the section being dredged, from about 12th to Ninth. A similar dam is on the upstream end of the pipe. The historic canal is being cleared of sediment and vegetation to restore its capacity. It feeds the Vine Street water treatment plant and the power plant there.
