Hatchery Natural Area

Hatchery Location map Hatchery Natural Area is a 23-acre, mostly flat, low elevation valley property just up Big Soos Creek near its confluence with the Green River, immediately east of Highway 18 in Auburn, WA. The surrounding area includes the Soos Creek Hatchery, and King County's Porter Levee and Auburn Narrows Natural Areas. Currently, the Hatchery Natural Area is used for passive recreation activities such as walking, fishing or hiking. Although no formal trails or roads exist, visitors typically access the east side of the site from Auburn-Black Diamond and SE Lake Holm Rd. There is a wide area on the side of the road that visitors use for parking.

This section of the Middle Green River supports populations of coho, chinook and chum salmon, steelhead, rainbow, and resident and sea-run cutthroat trout. Bull trout have also been found. Other verified species of wildlife that use the property are deer, mergansers, great blue herons, beaver, nutria, and bald eagles.
