Fall River, California's largest spring creek, is nourished by icy aquifers originating from Mount Shasta's snows and glaciers. As the nation's largest spring system, it provides an enchanting habitat for crystal-clear, 50-degree rainbow trout. Recognized as the finest spring creek fly fishing opportunity in California and one of the best in the United States, it stands as the angling centerpiece of the Shasta Cascade region. Stretching about fifteen miles with an average depth of 7 feet, the Fall River is challenging to wade as the entire riverbank is privately owned, limiting public access.
