About Issaquah

Salmon give Issaquah an unusually visible seasonal clock. The city occupies a valley at the south end of Lake Sammamish, with Cougar, Squak, and Tiger mountains—the grouping known locally as the Issaquah Alps—rising around it. Issaquah Creek passes through the older center to a state hatchery built as a Works Progress Administration project beginning in 1936. Logging and coal mining had damaged local runs, and fish culture began there in 1937 as part of the effort to rebuild them. Coho and Chinook now return from the Pacific through the hatchery’s fish ladder. One of Washington’s few urban fish hatcheries, the site also offers year-round tours focused on the salmon life cycle. Their arrival can be watched at the creek and, when conditions permit, through cameras operated by the Washington Department of Fish and Wildlife.

The valley first grew around timber, coal, and rail service. Daniel Gilman brought the railroad, and the settlement was named Gilman before incorporating in 1892. The Washington State Legislature changed the name to Issaquah in 1899. Front Street and the surrounding Olde Town grid remain the city’s historic and civic center, where the depot museum, Village Theatre, library, and salmon hatchery sit within the same compact area. A former depot stands near shops and civic buildings, while the creek carries returning fish past blocks that developed around the rail line. Modern Issaquah has several centers with different scales. Costco has been based at Pickering Place since 1994, and its current corporate campus contains about 700,000 square feet of office space. Pickering Place lies within Central Issaquah, a roughly 1,100-acre commercial area covered by a transformation plan adopted in 2012.

East of the valley floor, Issaquah Highlands began receiving its first households in 1998 and now includes housing, shops, community space, and the Swedish Issaquah medical campus. Two major transit centers serve those districts, one in Central Issaquah and one in the Highlands. King County Metro’s on-demand Metro Flex also serves the city. Getting around remains a practical constraint: in Issaquah’s 2025 community survey, 25.8 percent of respondents were satisfied with using public transportation within the city. Olde Town, Pickering Place, and the Highlands present three recognizable versions of Issaquah: historic storefront blocks, large employment and retail sites, and a newer hillside urban village. Public events make use of those separate settings. Pickering Barn hosts the city’s Saturday farmers market from May through September in 2026, placing produce stalls and prepared-food vendors beside the Central Issaquah commercial district.

The market’s setting carries its own history: hay-barn construction began in 1878, a large dairy barn was added in 1906, and the site served for years as Issaquah’s largest dairy farm. Downtown, Village Theatre stages a full season, and the 2026 ArtWalk schedule brings music and artwork to Front Street on summer evenings. The largest gathering follows the fish themselves. The 57th Salmon Days festival is scheduled for October 3 and 4, 2026, with arts, performances, food, and family activities spread through downtown. At the same time, returning coho and Chinook can be seen climbing the hatchery ladder a few blocks away, joining a regional street festival to the biological event it names.
