Newboro, situated on an isthmus between Newboro and Upper Rideau Lakes, played an important role in the construction of the Rideau Canal, as witnessed by the memorial plaque to Army engineers who lost there lives during its construction. As commercial use of the canal declined Newboro became known for its great fishing. As a result several fishing lodges arose. Also one of the four Rideau Canal blockhouses is located here. Today Newboro offers food and accommodation to tourists and cottagers along the lake. It also provides the setting for an American Civil War Battle in August
