If you’ve heard one thing about Silver Creek, it’s probably that it’s one of the best trout streams in America—and one of the most challenging. Why is it that the great ones are always difficult?
For anyone who enjoys precision dry fly fishing in a pristine spring creek, Idaho has several excellent options, but few can match Silver Creek. This stream in Central Idaho is legendary for the size and abundance of its trout, and for the extreme skill needed to catch them. Like most things worth doing, it takes hard work to succeed here. But the rewards are potentially enormous. Some might say life-changing.
Silver Creek Hatches: What to Expect
Located just south of the Sun Valley near Ketchum, Silver Creek is just over 25 miles long. Its diminutive size is a double-edged sword. On one hand, you don’t have to explore several hundred miles of river to find the best spots. On the other, when one of the most renowned streams on earth is just 25 miles long, you don’t have to be a mathematician to calculate what that means for the fishing pressure.
Silver Creek gets its water from various springs, rivulets and tiny tributaries, so it doesn’t have a single headwater. Roughly the first 2 miles of the creek—and by far the most heavily pressured section—is located within Silver Creek Preserve.
Flowing through open grassland with few tall trees, Silver Creek has periodic broad, slow segments that are usually referred to as “ponds.” Most of the stream is soft-bottomed and has abundant aquatic vegetation. Brown trout and rainbow trout are both abundant and more than capable of reaching trophy size. A 30-inch fish of either species is possible.
Expert Tips for Fishing Silver Creek
Slow Down
Being in a hurry does not pay off here. Take your time. Don’t even tie on a fly until you’ve spent a few minutes crouched on the bank taking it all in. Take note of the current, look for trout rising, and pay special attention to any insects you see.
Once you start fishing, maintain a slow and careful approach. Don’t wade haphazardly and risk stirring up the bottom and sending plumes of sediment downstream. The trout in Silver Creek have masters degrees in avoiding anglers, and they are very easily spooked.
Don’t Cast Blindly
If you enjoy sight fishing, you’ve come to the right place. Don’t leave home without polarized sunglasses and a brimmed hat to block out the sun! One of the best ways to find success on Silver Creek is to spot a fish and target it specifically rather than blind casting, which is more than likely to spook any trout that may be nearby.
Match the Hatch
Look, “match the hatch” is important on most streams, but it’s really important on Silver Creek. This stream is a genuine bug factory, and it’s possible that multiple hatches could happen on any given day. Hatches might alternate throughout the day, and they may overlap. There’s also a good chance that multiple stages of the same hatch—emergers, duns and spinners—are present at the same time.
So, what hatches here? A lot of things. Multiple baetis species, collectively referred to as Blue Winged Olives, hatch in spring and fall. Pale Morning Duns, Mahogany Duns, Tricos, Green and Brown Drakes may also be on the menu, and the summer Speckle Wing Quill hatch can be hugely important.
Spotted Sedges and Green Sedges are a couple of the most important caddis varieties, both hatching from June through August and the latter may extend into September. Green Sedge larvae, called Rock Worms, are also eaten by trout. Several other caddis species may be present, along with various stoneflies, midges terrestrials, damselflies and scuds.
Throw Dry Flies
There’s no rule against nymphing on Spring Creek, but it really is a dry fly stream first and foremost. That’s partly because the tremendous amount and variety of insect hatches often draws trout to the surface and facilitates dry fly fishing, but also because the stream conditions make it hard to fish a nymph effectively.
The real barrier to effective nymphing is the abundant aquatic vegetation, in which trout commonly hide. Getting a nymph close enough to the bottom to do any good usually means burying it deep in the weeds, and you’ll spend far more time getting hung up than you will catching fish.
Consider a Float Tube
If ever there was a great stream for float tube fishing, Silver Creek is it. One reason is that the stream is too deep to wade safely in many places, which limits most anglers’ options outside of the preserve. You can’t enter and exit the stream on private property, but the creek itself is state-owned and open to the public, so you can fish more of it with a float tube as long as you stay in the water.
Arrive Early, Stay Late
The most prolific hatches and consistent trout activity tends to happen outside of business hours. The Silver Creek Preserve is open year-round from dawn to dusk; and dawn and dusk are the best times to be there.
Apply the same logic to planning your trip by season. Summer is a beautiful time to fish Silver Creek, but it’s also the busy season. Try to fish the stream in late May and early June—when most trout haven’t seen a fly since the previous year—or in late fall when sunny days can trigger late-season hatches on the nearly deserted stream.
Silver Creek Access and Regulations
When fishing in Silver Creek Preserve, anglers are required to enter and exit the stream at designated points to avoid damage to the bank. Do your best to stay on gravel while wading, and avoid mud-bottomed areas that are more easily damaged. You must also sign in either electronically or in person before entering the preserve. The downstream boundary of the Silver Creek Preserve is Kilpatrick Bridge, which crosses a section known as Kilpatrick Pond and provides the first access outside the preserve. The Highway 20 Bridge also provides access, and additional sites are managed by Idaho Fish & Game at The Willows (aka “West Access”), Point of Rocks (aka “East Access”) and Picabo Access.
