    Prepared in cooperation with the Sauk-Suiattle Indian Tribe Suspended-Sediment Concentration in the Sauk River, Washington, Water Years 2012-13 By Christopher A. Curran1, Scott Morris2, and James R. Foreman1 1 U.S. Geological Survey, Washington Water Science Center, Tacoma, Washington 2 Department of Natural Resources, Sauk-Suiattle Indian Tribe, Darrington, Washington Photograph of glacier-derived suspended sediment entering the Sauk River immediately downstream of the Suiattle River mouth (August 5, 2014, Chris Curran). iii Introduction The Sauk River is one of the few remaining large, glacier-fed rivers in western Washington that is unconstrained by dams and drains a relatively undisturbed landscape along the western slope of the Cascade Range. The river and its tributaries are important spawning ground and habitat for endangered Chinook salmon (Beamer and others, 2005) and also the primary conveyors of meltwater and sediment from Glacier Peak, an active volcano (fig. 1). As such, the Sauk River is a significant tributary source of both fish and fluvial sediment to the Skagit River, the largest river in western Washington that enters Puget Sound. Because of its location and function, the Sauk River basin presents a unique opportunity in the Puget Sound region for studying the sediment load derived from receding glaciers and the potential impacts to fish spawning and rearing habitat, and downstream river-restoration and flood- control projects. The lower reach of the Sauk River has some of the highest rates of incubation mortality for Chinook salmon in the Skagit River basin, a fact attributed to unusually high deposition of fine-grained sediments (Beamer, 2000b).

Glacier Peak, a North Cascade dacitic stratovolcano near Darrington, Washington, has produced at least three large eruptive episodes See Figure 2 14 path of lahars since the culmination of the last continental glaciation with each episode likely lasting a few hundred years. Data from recent detailed geologic mapping, new C ages, stratigraphic relations, clast petrographic analyses, geochemical analyses, and laharic SKAGIT to lower Skagit Valley ISLAND sand composition indicate that three large eruptive episodes occurred in the latest Pleistocene and Holocene—the information refines and expands on the pioneering work of Beget (1981). These voluminous events traveled up to 135 km downvalley of the path of lahars to lower Stillaguamish Valley Glacier Peak edifice and reached the Puget Sound via the ancient Skagit and Stillaguamish deltas. Glacier Peak has erupted dacite of similar composition throughout its history. Hypersthene-hornblende-(augite)-phyric vesicular lahar clasts found from Glacier Peak to La volcano 48° SNOHMISH Conner, Washington have similar geochemistry to dacite flows sampled on the volcano. Radiocarbon dating of the White Chuck assemblage shows an eruptive episode of ~11,900 yrs B.P.

  • Puget Sound Salmon Habitat Assessment: Landscape Level Subwatershed Prioritization
    CONSERVATION PRIORITIES: AN ASSESSMENT OF FRESHWATER HABITAT FOR PUGET SOUND SALMON PREFACE This report entitled Conservation Priorities: An assessment of freshwater habitat for Puget Sound Salmon was prepared at the request of the Trust for Public Land (TPL) to provide a regional snapshot of Puget Sound’s most pristine, intact freshwater salmon habitat. TPL is a leading land conservation organization whose mission includes conserving land for people which often means protecting habitat critical to the health of salmon and other species. We believe the assessment can complement and enhance the work of many organizations that are striving to recover our Puget Sound salmon runs. The assessment is a synthesis of existing information and expert opinion. The report describes or attempts to draw from what is known, published and described by experts within agencies, tribes and watershed groups having direct knowledge of these ecosystems and populations. The assessment provides a priority listing and map of the most intact freshwater habitats for salmon in the Puget Sound. The prioritized list of habitats, together with the summarized information and compiled sources, can be used to help guide cost- effective conservation decision making in the near term for the benefit of salmon and encompasses the whole Puget Sound basin. Dr. Chris Frissell, of the Flathead Lake Biological Station at the University of Montana; Peter Morrison, Pacific Biodiversity Institute; Jim Kramer, natural resource consultant; and Marie Mentor, a consultant and former TPL Washington State Director, were retained to produce the assessment. This effort would not have been possible without the significant support provided by The Brainerd Foundation, the Kongsgaard-Goldman Foundation, King County, the Bullitt Foundation, and in-kind contributions from Pacific Biodiversity Institute and TPL.

  • Glacier Peak — History and Hazards of a Cascade Volcano
    USG S U.S. GEOLOGICAL SURVEY — REDUCING RISK FROM VOLCANO HAZARDS Glacier Peak — History and Hazards of a Cascade Volcano lacier Peak is the most Gremote of the five active volcanoes in Washington State. It is not prominently visible from any major popu- lation center, and so its attractions, as well as its hazards, tend to be over- looked. Yet since the end of the last ice age, Glacier Peak has produced some of the largest and most explosive eruptions in the state. During this time period, Glacier Peak has erupted multiple times during at least six separate Baker episodes, most recently Pacific Ocean about 300 years ago. What Glacier Peak lies in Washington State’s North Cascade Mountains, were these eruptions like? Glacier in the heart of a wilderness area bearing its name.
