Pleasant River Navigation Project

The Pleasant River flows southeasterly through Columbia Falls and Addison to Pleasant Bay, about eight miles west of Jonesport. It is used by local fishing boats.

Corps’ work in the river included removing boulders in the four mile reach between Columbia Falls and Addison; installing a stone beacon to mark ledges along the channel; and installing a spindle to mark a shoal near Addison. This work was completed in 1891.
