Silver Creek Preserve

Gliding across the water, settled into the seat of a canoe, it’s not hard to understand why years of work and collaboration have been dedicated to protecting Silver Creek—it is a magical place.

In no small part, the wonder of Silver Creek’s story comes from the people who came together to make it a reality. It started in 1976 when the local community urged The Nature Conservancy to purchase 479-acres then called the Sun Valley Ranch and create its flagship preserve, Silver Creek. This launched a landowner conservation effort along the stream to protect an additional 12,000-acres through conservation easements, making this one of the most successful stream conservation efforts ever undertaken for public benefit and a model for community-based conservation.

Over the last forty years TNC Idaho has expanded the Preserve to 881-acres and restored this high-desert spring creek to a thriving ecosystem for an abundance of wildlife including eagles, coyotes, bobcats, and moose. As many as 150 species of birds have been identified along the nature trail and its globally unique aquatic ecosystem features one of the highest densities of stream insects in North America.

TNC Idaho and our partners are working together to expand restoration efforts across the Silver Creek Watershed and its native fishery. We are developing science-based restoration projects in the system to restore stream function, enhance aquatic habitats and expand riparian buffers. Projects include improvements to channel conditions, hydrologic functions, fish habitat complexity, riparian buffers and floodplain connectivity.

Silver Creek Watershed

The water that flows into Silver Creek Preserve may originate in a series of springs, but the path it takes before it reaches Silver Creek is a complicated one. The Nature Conservancy in Idaho recognizes that in order to keep Silver Creek’s aquatic ecosystem healthy, we must consider the health of the entire watershed.

That's why TNC Idaho collaborates with partners, landowners and individuals to find lasting solutions to our conservation challenges throughout the landscape. Working together, we can achieve a bright future for this special waterway—a creek like none other in the world.

So far, twenty-two landowners have donated nearly 10,000 acres in conservation easements, protecting nearly the entire main stem from development.

The health of the Silver Creek watershed and its aquatic ecosystem are dependent on water quantity and quality. Changes in water availability and water-use practices in the Wood River system have impacted the Big Wood River and its aquifer, which, as the primary water source for Silver Creek, has affected stream flows and increased water temperatures. In addition, land use practices have affected the integrity and effectiveness of riparian buffer zones, sediment loads, and water quality in Silver Creek and its tributaries.

A paradigm shift in water management was needed. To catalyze this, TNC Idaho helped form the Wood River Water Collaborative (WRWC), to develop proactive solutions to resolve water conflicts and improve water use in the Wood River watershed. From its creation there has been an effort to include all interested stakeholders in the WRWC. The Collaborative has agreed to three overarching goals which include:

In the Field

In partnership with the Silver Creek Alliance, we completed a geomorphic assessment of the entire Silver Creek Watershed. The report synthesizes and builds upon all the aquatic and riparian studies completed for Silver Creek and its tributaries to-date. It also identifies high priority needs and opportunities for restoration to benefit Silver Creek’s wild trout fishery. With a wholistic approach to understanding ecological issues and strategies for restoration throughout the system, TNC Idaho and our partners are developing science-based restoration projects. These projects will restore stream function, enhance aquatic habitats and expand riparian buffers. This work includes:

  • Restoring stream channel and floodplain complexity.
  • Increasing stream habitat connectivity and improving fish passage.
  • Protecting water quality and maintaining cooler water temperatures year-round on tributary streams through riparian plantings and increased streambank cover.
  • Working with the U.S. Geological Survey, Silver Creek Alliance and the State of Idaho on water quality, streamflow, insect and fish surveys.
  • Continuing restoration and monitoring of the water and wildlife of Silver Creek Preserve.

Maybe it will be a trophy trout that draws you to Silver Creek; always feeding, but never interested in your fly. Maybe you'll come to hear the cry of the sandhill cranes as they return in the spring or the flocks of waterfowl whistling overhead on their fall migration. Or perhaps you'll make the trip to see that legendary, glorious light: A light that seems designed by a photographer, or an artist, with its rich pastel of purples, reds, yellows and blues.

Whatever the reason, we know your heart will be captured by this special place in Idaho's high desert.

Each year, the Preserve draws visitors from all 50 states and more than a dozen countries. The fly fishing is legendary, of course, but the Preserve offers many other outdoor activities.
