We'll let The Fly Shop explain the waters of Fall River: "It is the nationa's largest spring system, creating a wonderland of crystal-clear, 50-degree rainbow trout habitat. At the same time it is both the finest spring creek fly fishing opportunity in California and one of the best in the United States. It is certainly the angling showpiece of the entire Shasta Cascade region and one of the richest spring fed rivers in the world." Makes you want to grab your gear, doesn't it? Fish for Rainbows on Fall River from the last Saturday in April through November 15th.
