The 4015-acre basin below has been a world-famous forest and water laboratory since 1933. Here, a variety of forest cutting experiments have increased flow of pure water by almost a half million gallons per acre per year without increasing soil erosion or flooding. These classic experiments have shown that the forest ecosystem can be managed without ruining the priceless water it produces. Research continues to learn how these forests can best be managed to serve the public’s water, timber, wildlife and recreation needs.
