DESCRIPTION
The
Kittitas Conservation Trust will use this grant to produce preliminary designs
for a habitat restoration project in lower Gold Creek, a tributary to the upper
Yakima River. Gold Creek starts in the Alpine Lakes Wilderness then flows into
Lake Keechelus near Snoqualmie Pass in northern Kittitas County. It is used by
Bull Trout, which are listed as threatened with extinction under the federal Endangered
Species Act. Humans have disturbed the Gold Creek watershed by logging, mining,
impounding water, and development activities including construction of roads and
railroads. These historic disturbances have altered natural processes, degraded
habitat, and resulted in portions of the creek drying up each summer, causing
bull trout mortality and impeding migration to their spawning grounds. The
cumulative impacts have resulted in an over-widened channel that lacks
complexity. Designs will focus on projects that will narrow and stabilize
stream banks, restore floodplains, increase stream flow complexity, encourage
regeneration of shoreline forests, increase the number of shaded pools, and
decrease the time and amount of the creek that dries up.
Kittitas Conservation Trust used this grant to produce preliminary design documents for instream habitat restoration in lower Gold Creek, a headwaters tributary to the upper Yakima River. Gold Creek originates in the Alpine Lakes Wilderness, then flows into Lake Keechelus near Snoqualmie Pass in northern Kittitas County (WRIA 39). It supports a threatened population of bull trout. The preliminary designs were supported by the scientific findings expressed in the Gold Creek Habitat Assessment and Conceptual Design Project (RCO #12-1306) that documented the underlying causes for degraded bull trout habitat in the project reach, River Mile 1.0 - 2.1. The Gold Creek watershed has experienced major human disturbances including logging, mining, water storage impoundments, and residential, road, and railway development. These historic disturbances have altered natural processes and hydrologic conditions, resulting in degraded habitat and seasonal dewatering. The cumulative impacts have resulted in an over-widened channel that lacks instream complexity. Designs focus on instream restoration actions that will narrow and stabilize stream banks, restore adjacent floodplains, increase stream flow complexity and wood loading, encourage regeneration of riparian forests, increase quantity of pools with cover, and decrease the duration and extent of seasonal dewatering. Hydrological data gathered during the preliminary design phase will also inform restoration strategies for Gold Creek Pond. In 2016, KCT requested a cost increase of $12,186, to address the need for more stakeholder meetings and landowner outreach as the project is adjacent to many private landowners who have a interest in the project development. The funding went to additional meetings in Seattle, individual landowner meetings for creek-side property, and frequent stakeholder updates on project progress.
