Location Map for Peterson Lake Natural Area near Maple ValleyThe Peterson Lake Park Natural Area is located near Maple Valley, WA in the middle of the Peterson Creek basin. King County acquired the 153-acre Natural Area in its Waterways 2000 Program, to help preserve water and habitat quality in the Cedar River Watershed.

Peterson Lake Natural Area contains coniferous and deciduous forest, open water, scrub-shrub and forested wetlands, and several year-round and seasonal tributaries. The wetland system at Peterson Lake is rated as Class 1 for its size, diversity of vegetation, open water component, and presence of Labrador Tea. The wetlands and the upland forests provide habitat for resident and migratory birds, terrestrial and aquatic mammals, fish, amphibians, and reptiles. Downstream of Peterson Lake, Peterson Creek flows through a corridor of largely intact forest on privately owned land to the Cedar River.

The site is appropriate for passive recreational use, such as walking or nature observation. Peterson Lake is located between the cities of Renton and Maple Valley near the intersection of SE Petrovitsky Road and 196th Avenue SE. Most parking occurs at this intersection along Seattle Public Utilities’ SE Pipeline Road directly above the lake. A small vehicle pullout along 196th Avenue is located directly across the road from the existing upper forest trail access point.
