Deep Lake, the center of the park, is a deep-water kettle lake formed by retreating glacial ice during the last ice age.
The park was originally donated to the state by the Weyerhaeuser Company in the mid-20th century.
The surrounding landscape is part of the Pacific Northwest temperate rainforest ecosystem, featuring Douglas fir and Western hemlock.
The park is home to a variety of seasonal migratory birds, including Great Blue Herons and various duck species.
The lake depth is significant despite its relatively small surface area, contributing to its distinct, clear water clarity.
Nolte State Park is a 117-acre day-use park situated on the shores of Deep Lake in Enumclaw, Washington. The park features a 1.2-mile interpretive loop trail that encircles the lake, passing through second-growth forest and wetlands. Deep Lake is a glacial kettle lake known for its calm water, which is popular for non-motorized boating and seasonal fishing. Birdwatchers frequently observe waterfowl and raptors along the lake perimeter. The site provides a swimming beach and multiple picnic areas for public use. It serves as a primary access point for recreational activities in the surrounding Green River Valley area. The park terrain is generally flat, making it accessible for casual hikers.

Bring polarized sunglasses to better view the aquatic life and lake bottom clarity near the shore.
Pack insect repellent during the summer months, as the lake-adjacent wetlands can attract mosquitoes.
Do not attempt to swim outside the designated beach area, as some parts of the lake perimeter have steep drop-offs or soft, muddy banks.
Leash your dogs at all times and practice leave-no-trace principles; keep music volume low to maintain the quiet atmosphere.
