Rising in Orange County, the Eno River flows through an urban and suburban landscape before merging with the Flat and Little rivers to form the Neuse. This small river has been fought over by developers who wanted to exploit it and environmentalists who wanted to preserve it. In the late 1960s, Holger and Margaret Nygard helped organize the Association for the Preservation of the Eno River to defeat Durham's attempt to dam the river. The association has helped to set aside almost 4,000 acres for the Eno River State Park. This is over half of the 7,000 acres planned for the park. The association is finding it harder to acquire and protect the remaining acreage. Many people want to live next to protected wilderness lands, and this has caused real estate prices around the river to soar.
