Description
The County was named for a U.S. Senator from Missouri (1821–51) and later U.S. Representative (1853–55) Thomas Hart Benton. The County is located in the southcentral area of the state.

It is important to note where the population of Benton county resides.

Northern Benton county is a Federal Department of Energy Reservation (with the Hanford Nuclear Plants). No one has lived there since 1943. Before then it had a handful of rural communities.

Western Benton county is dominated by Prosser, with very close ties to other Yakima Valley communities. The Yakima River cuts a Valley through the regions rolling hills, and much of the population of Yakima County lives along the river in this valley, which creates a continuous connected group of towns and communities from Pomona in the north, through Yakima City, and into Benton County to Prosser, and Benton City. Many of the residence of western Benton County go to Prosser or into Yakima County for goods and services, as well as to go to the hospital, have children, get married, and for funeral services and burial.

Eastern Benton County is dominated by the Tri-City Metropolitan Area, the fourth largest metro area in Washington State. The three cities that the metro area is named for are Kennewick and Richland in Benton County and Pasco in Franklin County. It also includes the towns of West Richland and Finley (Benton County) and Burbank (Walla Walla County). The area has been a gathering place from prehistoric times because of the intersection of three major rivers. The Snake and the Yakima Rivers empty into the Columbia River in this location, hence it is also called the Three Rivers Region. The county boundaries follow the rivers, Benton county south and west of the Columbia, and Franklin and Walla Walla north and east of the Columbia, with the Snake River between them. From the first settlers in this area, there have been ferries and then bridges that connected these communities. Any resident in or near the confluence of the rivers may have records in Benton, Franklin or Walla Walla county.

The southern boundary of Benton is also the Columbia River, with Umatilla County, Oregon on the other side. The small cluster of communities along the Columbia in the south rely on services in Hermiston, Oregon.

Record Loss
There is no known history of courthouse disasters in this county.

As part of the Manhattan Project (see details below) all of northern Benton County was evacuated in 1943. There are *no* town or local records for the towns of Hanford, White Bluffs, or [Old] Richland (1905-1943). There are also no records for the 2 dozen small rural communities scattered throughout northern Benton county. There are federal census, and some school census for these areas, and a very few number of phone directories. There are several books of the personal memories of those evacuated, available in FHLC (see local histories below). Many of the graves in the White Bluff Cemetery were moved to Prosser Cemetery (a few moved to Richland or Kennewick). The graves were moved on very short notice by the family members then present. All remaining graves have no record whatever, and are completely unreachable.

[New] Richland was incorporated in 1958. They have *no* records prior to that date. Personal discussion with the city clerk assures me that even though they have the same name, there is absolutely no tie--legal, financial, records or jurisdiction, with the town of the same name in the earlier time period.
