You can drive down to Cheney Pond via an unmarked road along Boreas Road, on top of a hill with a pull-off. The road is somewhat rutted but there is a drive-in campsite at the bottom of the road. From there, you can paddle across Cheney Pond and follow a narrow but navigable stream down to Lester Flow, which is little more then a still water in the Boreas River. At one time, Lester Flow was a all flooded but the dam is long gone, just leaving the still water. Also on the blog under this category are orthphotos with campsites and roads shown.
