United States v. Dickinson

Background

Two West Virginia landowners sued the United States after construction of the Winfield Dam raised the Kanawha River and permanently flooded parts of their property and caused bank erosion. The dam was completed in 1937 and the river reached its final level in 1938. The owners brought claims under a federal law that lets people seek money when the Government takes private property; the suits were filed on April 1, 1943.

Reasoning

The main question was when the Government’s flooding became a completed “taking” for purposes of the six-year time limit. The Court said the taking here was a continuing physical process, not a single event that forced immediate lawsuits. It held owners need not sue prematurely while the damage and its full extent were still developing. The Court also reasoned that the United States must pay for all land it effectively appropriated, including land lost to erosion caused by the flooding, and that the cost of prudent prevention measures may measure such damages. The Court rejected the Government’s claim that one owner forfeited compensation by later reclaiming land, saying the taking occurred when the land was flooded.

Real world impact

The decision affirms money awards for the owners and upholds payments for permanent flooding, intermittent overflow rights, and erosion-related losses. Riverfront property owners affected by federal flood-control or navigation projects can wait until the harm stabilizes before suing, and they may recover the costs of reasonable protection measures caused by government works.
