  • Modeling the Effects of Climate Change on Streamflow and Stream Temperature in the South Fork of the Stillaguamish River
    Modeling the effects of climate change on streamflow and stream temperature in the South Fork of the Stillaguamish River Thesis Proposal for the Master of Science Degree, Department of Geology, Western Washington University, Bellingham, Washington Kate Clarke May 2018 Approved by Advisory Committee Members: _____________________________________________________________ Dr. Robert Mitchell, Thesis Committee Chair _____________________________________________________________ Dr. John Yearsley, Thesis Committee Advisor _____________________________________________________________ Dr. Douglas Clark, Thesis Committee Advisor Problem Statement My objective is to model the effects of forecast climate change on streamflow and stream temperatures in the South Fork Basin of the Stillaguamish River in northwest Washington State. I will use gridded historical meteorological data to calibrate the Distributed Hydrology Soil Vegetation Model (DHSVM; Wigmosta et al., 1994) to simulate hydrology and the River Basin Model (RBM; Sun et al., 2014; Yearsley 2009, 2012) to simulate stream temperature. I will then apply gridded forecast climate data that have been downscaled to the region to predict future changes in streamflow and stream temperature through the 21st century throughout the South Fork Basin. I predict that spring and summer streamflow will decrease, and stream temperatures will increase. The Stillaguamish River (Figure 1) is an important regional water resource and serves as critical habitat for several species of salmonids (Washington State Department of Ecology (WSDOE), 2012). The results of my study will help river managers to determine where to focus salmon habitat remediation efforts. Introduction The South Fork Basin encompasses approximately 38% (660 km2) of the Stillaguamish River Basin and serves as an important resource for local agriculture and industry and for habitat for fish (Figure 1).

HYDROELECTRIC PROJECT FERC No. 553 ROSS lAKE LEVELS ANALYSIS VOLUME I Report SKX 1991 § #10 I City of Seattle City light Department JUNE 1991 SKAGIT RIVER HYDROELECTRIC PROJECT FERC No. 553 Ross Lake Levels Analysis Volume I Report • Prepared by Ebasco Environmental, with assistance from Synergic Resources Corporation Submitted to Seattle City Light June 1991 EXECUTIVE SUMMARY I. Introduction The City of Seattle, City Light Department (the City) is the owner and operator of the Skagit River Hydroelectric Project, Federal Energy Regulatory Commission (FERC) No. 553. The original license for the project, issued in 1927, expired in 1977. Since that time, the City has been conducting a number of studies, many of them related to downstream fisheries. More recently, and in response to inquiries by FERC and the intervenors (1 ). the City has hired consultants to evaluate project impacts in several areas. One area of intensive study has been an analysis of the impact of Ross Lake levels. Operation of Ross Lake has been characterized by annual drawdowns of about 100 feet. (2) The lake is generally at or near full pool during the mid to late summer months, and reaches its lowest level in early spring. The annual cycle of Ross Lake levels has impacts on, and is affected by, a number of other resources. These include: downstream anadromous fisheries electric power generation erosion (includes archaeological resources) flood protection recreation resident fisheries visual quality The relationships between Ross Lake levels and these resources are not only important, but most of them have not previously been quantified or otherwise studied in depth.

    UNITED STATES DEPARTMENT OF COMMERCE National Oceanic and Atmospheric Administration NATIONAL MARINE FISHERIES SERVICE West Coast Region 1201 NE Lloyd Boulevard, Suite 1100 PORTLAND, OREGON 97232 October 24, 2019 Dear Recipient: In accordance with provisions of the National Environmental Policy Act (NEPA), we announce the publication of the Final Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) for Four Salmon Hatchery Programs in the Stillaguamish River Basin. The proposed action is approval of four salmon hatchery programs under Endangered Species Act Section 4(d) Limit 6. The hatchery programs are described in Hatchery Genetic Management Plans prepared by the Stillaguamish Tribe of Indians and submitted collectively with the Washington Department of Fish and Wildlife. The National Oceanic and Atmospheric Administration’s (NOAA)’s Policy and Procedures for Compliance with the National Environmental Policy Act and Related Authorities: Companion Manual for NOAA Administrative Order 216-6A requires that NOAA prepare and publish a FONSI that concludes the NEPA process for an EA. The National Marine Fisheries Service has made available the Final EA electronically through the NOAA Fisheries West Coast Regional salmon and steelhead hatcheries website. The FONSI is included as Appendix E of the Final EA. Sincerely, Barry A.
