  • Skagit - Ferc Project #553
    SKAGIT - FERC PROJECT #553 EROSION CONTROL PROGRAM 2005 COMPLETION REPORT North Cascades National Park and Seattle City Light March, 2006 1 INTRODUCTION As stipulated in the 1991 Erosion Control Settlement Agreement (SA) between the National Park Service (NPS) and Seattle City Light (SCL), erosion control activities in Ross Lake National Recreation Area (NRA) continued for a twelfth year (including pre-license work). NPS crews, funded by SCL, conducted work at several sites in 2005 (Figure 1). Activity this year focused on contingency cribbing site E70A-6B, twenty yards south of E70A-6 on Ross Lake. In addition, site D-11, Thunder Point Campground on Diablo Lake was undertaken and completed. Detailed accounting of expenditures is provided in other reports and is not duplicated here. The purpose of this report is to update the Federal Energy Regulatory Commission (FERC) on progress under the terms of the new operating license for the Skagit Project. PROGRESS REPORTS BY PROJECT SITE D-11, Diablo Lake: Thunder Point Campground Approximately 250 ft of shoreline fronting the campground had become severely eroded. NPS erosion control crews in coordination with Seattle City Light barge, tug and boat crew imported 23 dump truck loads of building rock and one hundred yards of gravel. As per settlement agreement erosion control design, dry lay rock wall was installed to a height of 5’ along the 250’ of shoreline. Upon completion of dry wall, armor rock placed along the toe for the entire span. On the southwest end of the site, an additional 60’ of eroded shoreline was protected by half burying stumps in the drawdown and locking in drift logs in between the buried stumps and the shoreline creating a wave energy break.

Published monthly and semi-monthly during June by The Mountaineers, P.O. Box 122, Seattle, Washington 98111. Clubroom is at 7191h Pike Street, Seattle. Subscription price monthly Bulletin and Annual, $5.00 per year. EDITORIAL STAFF: Alice Thorn, editor; Loretta Slat­ er, Betty Manning. Material and photographs should be submitted to The Mountaineers, at above address, before Novem­ ber 1, 1969, for consideration. Photographs should be black and white glossy prints, 5x7, with caption and photographer's name on back. Manuscripts should be typed double-spaced and include writer's name, address and phone number. foreword Since the North Cascades National Park was indubi­ tably the event of this past year, this issue of The Mountaineer attempts to record aspects of that event. Many other magazines and groups have celebrated by now, of course, but hopefully we have managed to avoid total redundancy. Probably there will be few outward signs of the new management in the park this summer. A great deal of thinking and planning is in progress as the Park Serv­ ice shapes its policies and plans developments. The North Cross-State highway, while accessible by four­ wheel vehicle, is by no means fully open to the public yet. So, visitors and hikers are unlikely to "see" the changeover to park status right away. But the first articles in this annual reveal both the thinking and work which led to the park, and the think­ ing which must now be done about how the park is to be used.

  • North Cascades and Skagit Watershed Eco-Facts
    North Cascades and Skagit Watershed Eco-facts THE SKAGIT RIVER The Skagit River begins in southern British Columbia and flows 120 miles to Puget Sound, passing right by the Learning Center as Diablo Lake. In volume of water, it is the third largest river on the west coast of the contiguous United States. It is fed by over 3,000 streams and drains the largest watershed in the Puget Sound basin, an area roughly the size of Delaware. The Skagit is the only river system in Washington that supports all five species of salmon: Chinook, chum, Coho, pink and sockeye. It is home to six of the region’s 22 populations of threatened Chinook salmon and contains the largest listed bull trout, pink salmon and steelhead stocks in Washington. The Skagit Delta also supports huge concentrations of waterfowl, shorebirds and raptors, including trumpeter and tundra swans, snow geese, gray- bellied brant, rough-legged hawks, peregrine falcons and one of the nation’s largest gatherings of bald eagles. NORTH CASCADES MOUNTAINS Thrust up from the ocean floor in a tectonic collision millions of years ago, the North Cascades have been chiseled by glaciers into a jagged mountain realm full of sharp, stony peaks, deep valleys and long lakes. The North Cascades are part of the American Cordillera, the mountain chain that stretches more than 12,000 from Tierra del Fuego to the Alaskan Peninsula. Mile for mile, the North Cascades are steeper and wetter than nearly any other range in the conterminous U.S., and they are the most glaciated American mountains outside of Alaska.

Recreational Located east of 1-5, there are many opportunities for you to enjoy this area with easy access Opportunities from several major highways. Start in the north and take a drive on the Mt. Baker Scenic Byway page 2 (State Route 542). This route begins in Bellingham, winds along the North Fork of the Nooksack River, and, from the town of Glacier, climbs 24 miles to an elevation of 5,100 feet at Artist Point in Heather Meadows. This destination is legendary for spectacular views of Mt. Baker, Mt. Shuksan and surrounding peaks. For other stunning vistas, follow the northern part of the Cascade Loop along the North Cascades Scenic Highway (State Route 20). A side trip up the Baker Lake Road, 16 miles east of Sedro-Woolley, leads into the Baker Lake Basin, which features campgrounds, water recreation, and numerous trails. Trip Planning and Safety page 3 The 125-mile Skagit Wild and Scenic River System - made up of segments of the Skagit, Cascade, Sauk, and Suiattle rivers - provides important wildlife habitat and recreation. The Skagit River is home to one of the largest winter populations of bald eagles in the United States and provides spawning grounds for one-third of all salmon in Puget Sound. The North Cascades Scenic Highway winds east £ through the gateway communities of Concrete, D Rockport, and Marblemount before reaching Ross Lake National Recreation Area within North Q Baker Lake Cascades National Park Service Complex.
