OREGON — For months, the surface of a popular boating waterway in Clackamas County has been jammed with logs and branches, stretched across 60 acres of surface water. But that’s already starting to change. Portland General Electric, which manages the dam at one end of the log-choked North Fork Reservoir, said on Thursday that the company has started the painstaking process of removing the logs and debris, which washed into the waterway during December’s heavy flooding. PGE spokesperson Grace Boehm said that most of the logs ended up in the reservoir over the course of a short period that also dumped 62,000 cubic feet per second worth of water into the reservoir — notching a place as the 4th highest flow into the waterway on record. …PGE will be setting aside 800 logs from the recovery effort for the company to donate to stream restoration habitats.
