The Yakima River basin is located in south central Washington State (Figure 1). The basin supports one of the most productive agricultural areas in the State, and production is valued at more than $4.481 billion dollars (WSDA, 2018). The agriculture industry is reliant on developed irrigation projects that have an impact on native populations of salmon and trout within the basin. Figure 1. Location of the Yakima River basin and its numerous tributaries. The Yakima River and tributaries historically supported culturally and economically significant salmonid runs of Sockeye (Oncorhynchus nerka), steelhead (O. mykiss), Coho (O. kisutch) and Chinook (O. tshawytscha). In addition to anadromous fishes, the headwaters of Yakima River tributaries supported healthy populations of fluvial and adfluvial Bull Trout (Salvelinus confluentus). Of these, Sockeye, Coho, and summer run Chinook salmon were extirpated from the basin, and both Middle Columbia River (MCR) steelhead and Bull Trout Yakima Basinwide Tributaries Programmatic Investigation Report 1 are currently protected under the provisions of the Endangered Species Act (ESA) as threatened. Historically, water rights within the Yakima River basin were highly contested, more so during times of drought. Water shortages and litigation between water users led to mistrust between State, Federal, Tribal, and local entities. This led to the adjudication of surface water rights starting in 1977 and authorization of YRBWEP in 1979 to improve water supply, conserve water, and improve fish passage. Greater emphasis on water conservation, identifying additional storage needs, and tributary enhancement were amended into the legislation that authorized YRBWEP in 1994. In 2009, the Bureau

  • Naches Watershed Washington
    Washington Naches Watershed HUC: 17030002 Rapid Watershed Assessment This assessment involves the collection of quantitative and qualitative information to develop a watershed profile, sufficient analysis of that information to make qualitative statements as to resource concerns and conditions, and the generation of information with which to make decisions about conservation needs and recommendations. These assessments are conducted through the use of Geographic Information System (GIS) technology and by conservation planning teams working within the watershed, meeting with landowners and conservation groups, inventorying agricultural areas, assessing current levels of resource management, identifying conservation recommendations and, making qualitative estimates of the impacts of conservation on local resource concerns. October 2, 2006 1 Naches Watershed Introduction 717,048 Total Acres HUC# 17030003 The Naches Watershed is located in the Yakima River drainage in on the east side of the Cascade Mountain range. The Naches 8-Digit Hydrologic Unit Code (HUC) subbasin is approximately 717,048 acres in size. The watershed is 20% privately owned and 80% publicly owned. The majority of the watershed is forest and cropland. Cropland is located mostly in the lower elevations. Agricultural enterprises include hay and pasture, orchards and small beef operations. The city of Naches makes up the largest urban area in the watershed. The majority of the watershed is located in Yakima County. Major resource concerns are soil erosion from forest roads, streambank erosion, impaired water quality, forest health issues, invasive weeds, and poor pasture condition. Primary natural resource technical assistance is provided by the Yakima NRCS Field Office, North Yakima Conservation District and the South Central Resource Conservation and Development Area.

Mid-Columbia Recovery Unit Yakima River Basin Critical Habitat Unit 353 Bull Trout Final Critical Habitat Justification Chapter 11 U. S. Fish and Wildlife Service September 2010 Chapter 11. Yakima River Basin Critical Habitat Unit The Yakima River CHU supports adfluvial, fluvial, and resident life history forms of bull trout. This CHU includes the mainstem Yakima River and tributaries from its confluence with the Columbia River upstream from the mouth of the Columbia River upstream to its headwaters at the crest of the Cascade Range. The Yakima River CHU is located on the eastern slopes of the Cascade Range in south-central Washington and encompasses the entire Yakima River basin located between the Klickitat and Wenatchee Basins. The Yakima River basin is one of the largest basins in the state of Washington; it drains southeast into the Columbia River near the town of Richland, Washington. The basin occupies most of Yakima and Kittitas Counties, about half of Benton County, and a small portion of Klickitat County. This CHU does not contain any subunits because it supports one core area. A total of 1,177.2 km (731.5 mi) of stream habitat and 6,285.2 ha (15,531.0 ac) of lake and reservoir surface area in this CHU are proposed as critical habitat. One of the largest populations of bull trout (South Fork Tieton River population) in central Washington is located above the Tieton Dam and supports the core area.

Our story begins with volcanism—effusive and explosive that resulted in lava flows, lahars, dikes, and stratovolcanoes. Over time, weathering as well as erosion by glaciers, rivers, and landslides have shaped the volcanics. Recent landslides and floods have dramatically altered this area. Stops will include the early Pleistocene? Sanford Pasture landslide, the October 2009 Nile Valley landslide, Miocene Edgar Rock Volcano, and Quaternary Boulder Cave–all in the middle Naches River Valley. 2 Enroute to Stop 1 • On I-82, we go over three prominent NW-SE trending up-folds or anticlines—Manastash Ridge, North Umtanum Ridge, and South Umtanum Ridge. These folds, and some associated thrust faulting, are the result of ~N-S compression. • If the weather is clear, note Mount Rainier and Mount Adams, the towering stratovolcanoes that dominate the South Cascades.

  • Suggested Fishing Destinations in Central Washington the Yakima
    Suggested Fishing Destinations in Central Washington Always refer to the WDFW Fishing Regulation Pamphlet prior to fishing any of these streams. Most of these are within an easy drive of Red’s Fly Shop, or even a day trip from the Puget Sound area. The east slopes of the Cascades are regarded as the best small stream fishing in Washington State and a GREAT place to start as a beginner! Most of the fisheries here offer small trout in abundance, which is great adventure and perfect for learning the art of fly fishing. The Yakima River Canyon The Canyon near Red’s Fly Shop is best wade fished when the river flows are below 2,500 cfs. September and October are the best months for wading, but February and March can offer great bank access as well. Spring and summer are more challenging but still possible. Yakima County Naches River – Trout tend to be most abundant upstream from the Tieton River junction. The best wade fishing season is July – October Tieton River – It runs fairly dirty in June, but July – mid August is excellent. Rattlesnake Creek – This is a great hike in adventure and offers wonderful small stream Cutthroat fishing for anyone willing to get off the beaten path. Little Naches River – Easy access off of USFS Road 19, July – October is the best time. American River/Bumping Rivers – These are in the headwaters of the Naches drainage. Be sure to read the WDFW Regulations if you fish the American River. Ahtanum Creek – Great small stream fishing. June – October Wenas Creek – Small water, small fish, but a great adventure.

  • The Wild Cascades
    THE WILD CASCADES Fall, 1984 2 The Wild Cascades PRESIDENT'S MESSAGE ONCE THE LINES ARE DRAWN, THE BATTLE IS NOT OVER The North Cascades Conservation Council has developed a reputation for consistent, hard-hitting, responsible action to protect wildland resources in the Washington Cascades. It is perhaps best known for leading the fight to preserve and protect the North Cascades in the North Cascades National Park, the Pasayten and Glacier Peak Wilderness Areas, and the Ross Lake and Lake Chelan National Recreation Areas. Despite the recent passage of the Washington Wilderness Act, many areas which deserve and require wilderness designation remain unprotected. One of the goals of the N3C must be to assure protection for these areas. In this issue of the Wild Cascades we have analyzed the Washington Wilderness Act to see what we won and what still hangs in the balance (page ). The N3C will continue to fight to establish new wilderness areas, but there is also a new challenge. Our expertise is increasingly being sought by government agencies to assist in developing appropriate management plans and to support them against attempts to undermine such plans. The invitation to participate more fully in management activities will require considerable effort, but it represents a challenge and an opportunity that cannot be ignored. If we are to meet this challenge we will need members who are either knowledgable or willing to learn about an issue and to guide the Board in its actions. The Spring issue of the Wild Cascades carried a center section with two requests: 1) volunteers to assist and guide the organization on various issues; and 2) payment of dues.

  • Chapter 1 Introduction
    CHAPTER 1 INTRODUCTION The rivers and streams within the Yakima River watersheds are valuable resources for Yakima County residents. The Ahtanum and Wide Hollow basins have been centers of irrigation and orchards since the turn of the 20 th century, contributing to the local economy and receiving diverted flows from the Naches River. Ahtanum Creek also forms the northern boundary of the Yakama Nation Reservation. Both basins are designated by the County Engineer as “Flood Prone” as they have been subject to frequent and extensive flooding. The two basins experienced accelerating urban and suburban growth for the last 20 years for the Cities of Yakima and Union Gap. Lower value agricultural land previously subject to flood is now being converted to high value residential and commercial development. The two basins have over 80 public bridges accommodating the urban road system and numerous agricultural diversions creating entry paths for flood waters into unexpected areas. The Yakima County-Wide Flood Control Zone District (FCZD) is addressing this flood risk need by preparing this Comprehensive Flood Hazard Management Plan (CFHMP) for the Ahtanum and Wide Hollow basins. The Plan was developed by the FCZD and its consulting firm, Golder Associates, with cooperation and input from the jurisdictions, the public and all affected public agencies. It covers the entirety of the two basins (see Figure 1-1). Figure 1-1 Area Map and CFHMP Area Boundary 2 Ahtanum -Wide Hollow CFHMP CFHMPs are designed to help a community prevent future damages from flooding through a short term and long term approach. Flood hazard reduction planning, to be successful, must be comprehensive and take into account the entire river system.
