This cache has been archived.

hydnsek: Cache was swept away by the massive flooding of Issaquah Creek after our record rains. Trail is closed, and some of the needed interpretive signs are gone as well. Archiving as it's unclear when the area will be restored.

The cache was about six feet above the average creek level, under a bench, but evidence shows the creek flooded the entire area - digging trenches in the trails, pouring over the boardwalk. Many of the interpretive signs used for this cache are gone, as well as the kiosk. Creek looks to have been 100 ft wide here during the flood; lots of debris and uprooted trees. The boardwalk itself is in surprisingly good shape, though. Lake Sammamish State Park has plenty of maintenance ahead.

Geocache Description:

This cache was originally part of the Kokanee Quest, a series of nine geocaches that highlighted the restoration of kokanee salmon in the Lake Sammamish watershed.

The geocache is not at the posted coordinates. Read the page to figure out the correct coordinates to find the cache, which is in Lake Sammamish State Park. A Discover Pass is required for parking.

Issaquah Creek is the largest tributary to Lake Sammamish, and historically was one of the primary spawning streams for kokanee salmon. But first farming and then the homes and businesses of a rapidly growing community reduced the ability of the stream habitat to support kokanee. When Lake Sammamish State Park opened in the 1950s, visitors trampled the natural shoreline, destroying vegetation and causing erosion, leading to a lifeless waterfront that no longer supported salmon.

Over the past decade, Washington State Parks, in partnership with the City of Issaquah, King County, and the Mountains to Sound Greenway Trust, has restored nearly five acres of habitat around the creek mouth to improve conditions for fish and wildlife. This shoreline habitat is particularly critical to kokanee fry, which migrate here soon after they hatch. The goal is to restore a self-sustaining kokanee population of appr. 10,000 spawning adults on Issaquah Creek.

As you walk the trail and boardwalk, you'll pass through the restored habitat. The boardwalk ends at a viewing platform by the creek mouth. You can go down the stairs and follow a short trail to the shoreline for great views of the lake. To your left, you'll see more of the restoration, including large logs and rootstocks that were placed (and anchored) to provide pools and resting areas for kokanee fry.

The posted coordinates take you to the boardwalk. To determine the correct cache coordinates, stroll the boardwalk and read the interpretive signs to find the answers to the questions below. Then substitute the numbers for the code letters in the final coordinate puzzle at the bottom.

  • What three salmon species currently spawn in Issaquah Creek?

    1. Chinook, coho, sockeye
    2. Chinook, coho, chum
    3. Chinook, coho, pink
    4. Chinook, sockeye, chum

    A = number before answer

  • As recently as the _____, thousands of kokanee spawned in Issaquah Creek each year.

    5. 1960s
    6. 1970s
    7. 1980s
    8. 1990s

    B = number before answer

  • How many years do kokanee spend in Lake Sammamish before returning to their home streams to spawn?

    1. 1-2 years
    2. 2-3 years
    3. 3-4 years

    C = number before answer

  • Which of these is not one of the ways that the area has been restored to improve kokanee survival?

    4. Deepening the creek channel to remove sediment and provide better fish passage.
    5. Placing woody debris to protect juvenile salmon.
    6. Planting native shrubs and grasses to filter pollutants and prevent erosion.
    7. Adding shoreline trees to shade and cool the water.

    D = number before answer

Final:   N 47° 33.[B-A]C[D+D] W 122° 03.[A+B][D-A]0

Substitute the numbers you got for A,B,C,D into the coordinate string above to determine the final three digits of latitude and longitude. [Brackets] are merely for grouping.

Unlike other salmon, the Lake Sammamish kokanee salmon lives its entire life in fresh water. Kokanee spawn in tributary creeks, and their offspring migrate to the lake as they mature, then return to their home creeks as adults to spawn the next generation.

Historically, the kokanee filled a critical ecological role within the Lake Sammamish watershed and was an important food and cultural resource for local tribes. But this "little red fish" has experienced a dramatic decline, leading to near-extinction in recent years.

To address the kokanee's plight, citizens, landowners, nonprofit agencies, and local, state, tribal, and federal governments have united to restore native kokanee salmon populations and the ecological integrity of the greater Lake Sammamish basin. In 2013, this group received an Urban Wildlife Refuge Partnership (UWRP) designation from the U.S. Fish and Wildlife Service, one of the first in the country.

The Kokanee Quest was sponsored by the Lake Sammamish UWRP, a consortium led by the King County Department of Natural Resources and Parks (KC DNRP) and the U.S. Fish and Wildlife Service (USFWS).
