Presentation Abstract

The Blackjack Creek watershed, 12.3 square miles in eastern Kitsap County, is among the largest and most productive salmon watersheds in the south Kitsap subregion. The watershed supports genetically-distinct summer and late fall runs of chum salmon, and coho and Chinook, as well as steelhead and cutthroat trout. Historic and current land uses in many parts of the Blackjack Creek watershed have substantially altered processes that drive ecosystem functions. The Suquamish Tribe conducted a watershed assessment to identify critical ecosystem components and key ecological attributes (KEAs), their current status, and human-caused pressures on KEAs. The goal was to build a plan, including strategies and actions, to protect and restore watershed, riparian, floodplain and stream processes and habitat functions for salmonids. The assessment includes a review of existing research, local studies, spatial data (GIS), and field data on freshwater and estuarine habitats and salmonid populations. Hydrologic patterns are identified and analyzed using “down-scaled” spatial data from Ecology’s Puget Sound Watershed Characterization Project to understand water flow processes in the subbasins of the watershed. These data are consolidated in a comprehensive assessment of human induced pressures and ecosystem stressors. The 13 strategies and 45 recommended actions in the plan address these specific pressures and are intended to protect and restore watershed processes and habitats. Strategies and actions are evaluated using a prioritization framework based on the principles of process-based restoration and climate change considerations. The plan will be used by the Tribe and project partners including the City of Port Orchard, Kitsap County, Kitsap Conservation District, Great Peninsula Conservancy and others to implement future protection and restoration in the Blackjack Creek watershed.

Using a watershed approach to identify protection and restoration actions in the Blackjack Creek watershed, Kitsap County, Washington

The Blackjack Creek watershed, 12.3 square miles in eastern Kitsap County, is among the largest and most productive salmon watersheds in the south Kitsap subregion.
