Eno & Environment

The river and the land around it, from mill sites to state parks.

The Eno powered local mills and later became a focus of conservation efforts: the Association for the Preservation of the Eno River Valley formed in 1966, the state park followed in 1973, and the fights over University Lake, Cane Creek, the Rogers Road landfill and the 1976 drought shaped how the county uses land and water. Hurricane Fran in 1996 belongs here too.

StorylineEno Presbyterian Church moves to Cedar Grove, 1879–18991879–1899 · 6 events · After wind-driven woods fires burned Eno Presbyterian Church at its old site near the river in 1893, the congregation moved to Cedar Grove. Its frame church, built in 1878, had hosted Orange Presbytery in 1879, a meeting the Chapel Hill Ledger called the best attended since the war. In October 1893 the pastor, W. F. Wilhelm, died at Hillsborough after a long fever, and every business in town closed for his funeral. At Cedar Grove the congregation built its new church from 1897 to 1899, and the elder Robert W. Anderson became the first burial in its cemetery in 1898. H. S. Bradshaw was installed as pastor on the last day of 1899. StorylineBattle Park and the Battle Park Association, 1914–19331914–1933 · 6 events · Kemp Battle's paths through Battle Park were restored from 1931 by volunteers who were then put in charge of the land around University Lake as well. Students cleaned the park's trails during Community Service Week in 1914, and by 1917 an open-air theatre stood on a hillside there. In 1931 a meeting at Colonel Joseph Hyde Pratt's home launched the Battle Park Association, and citizens working without pay under Pratt cleared paths and built bridges, opening about three miles of trail that year. In 1933 the association was incorporated, and the University trustees put it in charge of both Battle Park and the land around the new University Lake, where it ran motorboat rides to pay for more improvements. StorylineStreet trees of Chapel Hill, 1927–19351927–1935 · 3 events · Chapel Hill's aldermen decided in 1927 that the business block would keep its trees, though some merchants wanted it bare. On November 7 they refused a petition from five property owners to remove the trees and, with W. C. Coker's advice, voted to keep the existing ones, replace those already cut and plant new ones in the new sidewalk. At a crowded hearing on November 14 Moody Durham spoke for the merchants, but the board reaffirmed the policy. In late 1935 crews set out 200 willow oaks along the village streets, in what the Weekly called the largest tree-planting in the town's history, with saplings from the University and labor from the WPA. StorylineBen Johnston's Hillsboro mayoralty and its end, 1955–19611955–1961 · 6 events · Ben G. Johnston, Hillsboro's mayor since 1933, saw the town's new Eno River dam named for him before voters turned him out in 1961. In 1955 he won a twelfth term, and in 1956 the town commissioners named the dam for the mayor who had pushed for a town water system and led the bond drive for it. He won a fourteenth term in 1959 over Fred S. Cates Jr., who had campaigned for a city manager form of government. In 1961 Fred T. Claytor, a commissioner, teacher and coach, defeated him 279 to 159. The new board raised the property tax rate from 75 cents to $1 per $100, and Claytor cited a General Fund under $1,000. StorylineThe North Carolina Botanical Garden's first decade, 1966–19761966–1976 · 6 events · The North Carolina Botanical Garden opened its Mason Farm grounds in 1966, the year its support foundation was formed under William Lanier Hunt. It added a lake in 1967 and Azalea Hill in 1970. When the University refused it more money in 1973, Chapel Hill voted it $6,000, and in 1976 the Totten Center, its first permanent building, opened. StorylineThe University’s landfills and hazardous waste, 1970–19821970–1982 · 5 events · The University ended the towns' free use of its landfill in 1972, leaving Chapel Hill without garbage pickup while a restraining order held up the Eubanks Road site. In 1980 radioactive waste from a UNC lab went out with the trash to the Eubanks Road landfill. In 1982 UNC planned a new hazardous waste building and registered its two old waste landfills under the Superfund law.

  1. Indigenous communities occupy the Eno River Valley Excavations at the Hogue and Wall sites on the Eno near Hillsborough show farming communities growing corn, beans and squash, first in small scattered settlements (Haw River phase, about 1000–1400) and then in compact palisaded villages (Hillsboro phase, about 1400–1600). The Wall site village held perhaps 100 to 150 people in the mid-1400s. Place: Eno River valleySearch the index · UNC Research Laboratories of Archaeology, Ancient North Carolinians: Central Piedmont
  2. The Occaneechi settle on the Eno near Hillsborough After leaving the Roanoke River valley in 1676, the Occaneechi built a town on the Eno River near present-day Hillsborough and lived there from about 1680 to 1710. It was a small stockaded village of ten or twelve houses and probably fewer than 75 people, and it was the town John Lawson visited in 1701. Archaeologists dug the whole village between 1983 and 1986 at a place they named the Fredricks site, and they call this period of Occaneechi life on the Eno the Fredricks phase.

  3. Occaneechi Town on the Eno is largely abandoned By 1713, when the Occaneechi signed a peace treaty with Virginia at Williamsburg, their town on the Eno near present-day Hillsborough was almost empty. They moved north to Fort Christanna in Virginia, and some Saponi families later resettled in North Carolina.

Chairman Harvey Bennett opposed any further 'wet industry' near Hillsborough, citing a state water-resources report that urged limits on the plant's discharge into the Eno; Hillsborough Mayor Fred Cates backed the plant, and the company said it was looking at other sites.
