Hugo Black,
United States v. Sponenbarger…
“ An undertaking by the Government to reduce the menace from flood damages which were inevitable but for the Government's work does not constitute the Government a taker of all lands not fully and wholly protected. When undertaking to safeguard a large area from existing flood hazards, the Government does not owe compensation under the Fifth Amendment to every landowner which it fails to or cannot protect. In the very nature of things the degree of flood protection to be afforded must vary. ”
