Silver Creek is home to an abundance of rainbow, brown and brook trout.
Silver Creek is home to many hefty rainbow trout. Silver Creek, in south-central Idaho, is one of most fertile and prolific spring creeks in the country. Its cool, high-alkaline waters, lush with vegetation and teeming with aquatic insects, make it a perfect home for trout. The stream gathers from hundreds of smaller spring creeks flowing out of the southern end of Wood River Valley and the pastures below the town of Gannett. The steep mountains offer a beautiful backdrop to the smooth, placid creek and the flat high-desert country to the south and east.
