History

Telos Lake drained into the south end of Chamberlain Lake until the Telos Cut was excavated in 1841 to allow Telos Lake to drain east into Webster Lake and the Penobscot River. In the 1850s Eben S. Coe built the timber crib Lock Dam across the outlet from Chamberlain Lake causing Chamberlain Lake to overflow southward through Round Pond, Telos Lake, Webster Lake and Webster Brook into the East Branch Penobscot River in Baxter State Park. These changes allowed logs harvested in the upper Saint John River watershed to be floated to Bangor sawmills. The combined level of Chamberlain Lake, Round Pond, and Telos Lake has subsequently been regulated by Telos Dam.
