The area that is now Ike Kinswa State Park has a rich history deeply connected to the Cowlitz Indian Tribe, whose traditional territories extended across this region, including the confluence of the Tilton and Cowlitz Rivers. The park itself came into existence following the construction of the Mayfield Dam in 1963, which created the expansive Mayfield Lake reservoir. Originally known as Mayfield Lake State Park, it was renamed in 1971 to honor Ike Kinswa, a respected Cowlitz Indian leader who represented his people in the 1880s and was awarded a land patent in the Harmony community. This renaming serves as a significant tribute to the Indigenous people who first stewarded this land, recognizing their ancestral ties and the profound impact of the Mayfield Dam, which necessitated the relocation of many Cowlitz burial grounds. Today, the park stands as a recreational haven and a poignant reminder of the enduring presence and heritage of the Cowlitz people.
