Heath is a city in Rockwall and Kaufman counties, Texas, set along the eastern shore of Lake Ray Hubbard, roughly 23 miles east of Dallas. With about 9,800 residents, it is one of the smaller, more exclusive cities in the fast-growing Rockwall County corridor, and its identity is inseparable from the reservoir that defines its western edge. The city traces its origins to the 1840s, when settlers were drawn to the area's rich black soil and abundant wildlife, and it remained a rural farming community for more than a century. Heath's transformation began in the late twentieth century, when Lake Ray Hubbard—created in the late 1960s as a water-supply reservoir—became a centerpiece for recreation and lakefront development. The city emerged as one of North Texas's premier lakefront residential markets, with large custom homes, gated communities, and golf-course developments along the shoreline. The 787-acre Heath Golf and Yacht Club, with more than a thousand homes and resort-style amenities, exemplifies the city's lakeside orientation. The city's residents are served by Rockwall Independent School District, including Rockwall-Heath High School, located within Heath, and the private Fulton Academy. Heath's population reached 9,769 in the 2020 census, up sharply from 6,921 a decade earlier, reflecting the broader Rockwall County boom. Recreation centers on the lake, with parks, marinas, boating, and fishing woven into the community's daily rhythm, while the city balances its country roots—large lots, wooded creeks, and an unhurried pace—with proximity to Rockwall's retail corridors and the Dallas employment market. For buyers seeking lakefront living, top-of-market single-family homes, and a semi-rural setting within commuting distance of Dallas, Heath occupies a distinctive place in the metroplex's eastern arc.
