We know that the sun doesn't always shine and that the wind doesn't always blow. That means that solar cells and wind energy systems don't always provide electric power. Nevertheless, solar and wind energy seem to have captured the public's support as potentially being the primary or total answer to our electric power needs. Solar cells and wind turbines are appealing because they are "renewables" with promising implications and because they emit no carbon dioxide during operation, which is certainly a plus. But because both are intermittent electric power generators, they cannot produce electricity "on demand," something that the public requires. We expect the lights to go on when we flip a switch, and we do not expect our computers to shut down as nature dictates.

  • Lake Chelan Basin Overview View ‘Up-Lake’ of 90 Km (50 Mile) Long, 453 M (1486 Ft.) Deep Lake Chelan
    J. Riedel Contributions to the 2018 Pacific Northwest Friends of the Pleistocene Field Conference Stop 1.2: Lake Chelan Basin Overview View ‘up-lake’ of 90 km (50 mile) long, 453 m (1486 ft.) deep Lake Chelan. There are three basins comprising Lake Chelan separated by bedrock sills: Stehekin, Lucerne, and Wapato (Figure 2). The Lucerne Basin is the deepest and longest, with relief of > 3200 m (10,660 000 ft.) from the bedrock floor of the valley to the summit of Bonanza Peak (2900 m) on its west valley wall (Figure 2). The shallower Wapato Basin is in part dammed by glacial drift south of Chelan (Stop 1.4; Runner 1921). Figure 1. Location of Lake Chelan in north-central Washington. Blue arrows at top indicate Fisher and Rainy passes, where Cordilleran Ice Sheet entered Chelan watershed. Waitt (2017) noted the ice sheet was 760 m thick over Rainy Pass. Figure 2. Longitudinal profile of the bottom of Lake Chelan (top) and seismic profiling of sub-bottom (UW and NPS unpublished). The Lucerne and Stehekin basins are superimposed on resistant Skagit Gneiss and Tertiary igneous bedrock. The upper part of the valley is cut into resistant gneiss, which allows the canyon walls to stand near vertically along the upper lake. The deepest part of Lake Chelan occurs in the Lucerne Basin in The Straits near Falls Creek, where the bedrock changes from gneiss to erodible volcanic rocks and schist. The lower two basins are separated at the Narrows, an accumulation of landslide debris from Slide Ridge on the south shore, and bedrock on the north shore (Whetten, 1967).

  • Lake Chelan Recertification Review Report 2018
    REVIEW OF APPLICATION FOR RE-CERTIFICATION BY THE LOW IMPACT HYDROPOWER INSTITUTE OF THE LAKE CHELAN HYDROELECTRIC FACILITY Prepared by Patricia McIlvaine December 26, 2018; links added January 21, 2019 I. INTRODUCTION This report summarizes the review of the application submitted by the Public Utility District No. 1 of Chelan County (Chelan PUD or Applicant) to the Low Impact Hydropower Institute (LIHI) for re-certification of the Lake Chelan Hydroelectric Project FERC P-637 (Lake Chelan or Project). The Project was initially certified by LIHI as Low Impact in 2008 and re-certified in December 2012 as LIHI Certificate No. 30. The expiration date of the Certificate has been extended to allow for this review. This current re-certification review was conducted in compliance with LIHI’s Handbook, 2nd Edition, dated March 7, 2016. The December 2012 Recertification Report can be accessed via the link below. https://lowimpacthydro.org/wp-content/uploads/2012/12/Recommendation-Memo-Lake-Chelan- 2012.pdf The Project’s December 2012 re-certification had no conditions. II. RECERTIFICATION PROCESS AND INITIAL ASSESSMENT Under the 2016 LIHI Handbook, reviews are a two-phase process starting with a limited review of a completed LIHI application, focused on three questions: (1) Is there any missing information from the application? (2) Has there been a material change in the operation of the certified facility since the previous certificate term? (3) Has there been a change in LIHI criteria since the Certificate was issued? In accordance with the Recertification Standards, if the only issue is that there is some missing information, the applicant will have the opportunity to provide the missing information, and this may or may not trigger a Stage II review.

  • GEOLOGIC MAP of the CHELAN 30-MINUTE by 60-MINUTE QUADRANGLE, WASHINGTON by R
    DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP I-1661 U.S. GEOLOGICAL SURVEY GEOLOGIC MAP OF THE CHELAN 30-MINUTE BY 60-MINUTE QUADRANGLE, WASHINGTON By R. W. Tabor, V. A. Frizzell, Jr., J. T. Whetten, R. B. Waitt, D. A. Swanson, G. R. Byerly, D. B. Booth, M. J. Hetherington, and R. E. Zartman INTRODUCTION Bedrock of the Chelan 1:100,000 quadrangle displays a long and varied geologic history (fig. 1). Pioneer geologic work in the quadrangle began with Bailey Willis (1887, 1903) and I. C. Russell (1893, 1900). A. C. Waters (1930, 1932, 1938) made the first definitive geologic studies in the area (fig. 2). He mapped and described the metamorphic rocks and the lavas of the Columbia River Basalt Group in the vicinity of Chelan as well as the arkoses within the Chiwaukum graben (fig. 1). B. M. Page (1939a, b) detailed much of the structure and petrology of the metamorphic and igneous rocks in the Chiwaukum Mountains, further described the arkoses, and, for the first time, defined the alpine glacial stages in the area. C. L. Willis (1950, 1953) was the first to recognize the Chiwaukum graben, one of the more significant structural features of the region. The pre-Tertiary schists and gneisses are continuous with rocks to the north included in the Skagit Metamorphic Suite of Misch (1966, p. 102-103). Peter Misch and his students established a framework of North Cascade metamorphic geology which underlies much of our construct, especially in the western part of the quadrangle. Our work began in 1975 and was essentially completed in 1980.
