Kentucky Lake country
Marshall County is one of western Kentucky’s principal lake counties. The county seat is Benton. Kentucky Dam, which the Tennessee Valley Authority operates on the Tennessee River, stands near Gilbertsville and creates Kentucky Lake (Kentucky Reservoir). That single fact shapes a large share of the housing conversation here: lake homes, marina access, and weekend places sit alongside ordinary in-town houses in Benton, Calvert City, and Hardin.
Towns and communities
Census 2020 incorporated cities in Marshall County are Benton, Calvert City, and Hardin. Gilbertsville, at the north end of the lake near the dam, is a Census-designated place. Calvert City, in the northwestern part of the county, is also an industrial and highway community along I-24. Other lakeside neighborhoods exist around the reservoir; this page names only Census places so that informal community names are not presented as official city limits.
Lakes and parks
Kentucky Lake is the dominant water body. TVA’s Kentucky fact sheet describes Kentucky Reservoir as a large multi-purpose reservoir with extensive shoreline and public land under TVA stewardship. Kentucky Dam Village State Resort Park is the state park associated with the dam and Gilbertsville area (Kentucky State Parks). Land Between the Lakes National Recreation Area lies east of Kentucky Lake in Lyon and Trigg counties — a short drive across the water and I-24, but not inside Marshall County. Lake Barkley’s main Kentucky counties, per the Corps of Engineers, are Caldwell, Livingston, Lyon, and Trigg.
Schools
The Kentucky Department of Education district map shows Marshall County Schools as the county district and does not show an independent district in this county. Confirm school assignment by address with the district, especially for lake-area addresses that may sit outside a town’s corporate limits.
Getting around
Interstate 24 is the main freeway, running across the northern part of the county near Calvert City and the dam. U.S. 68 and U.S. 641 are the older routes through Benton and the lake communities and continue toward Murray (Calloway County, outside this 18-county guide set) and the Land Between the Lakes region. Paducah is a short drive northwest; Cadiz, Eddyville, and Hopkinsville are reachable on I-24 and U.S. 68.
Homes, farms, and land
Property types commonly include lake homes and lots, houses in Benton, Calvert City, Hardin, and the Gilbertsville area, plus farms and interior acreage away from the water. Tradewater Realty helps buyers and sellers with those property types. Dock rights, reservoir property rules, and flood or insurance questions on lake lots need a local, listing-specific review.
