Dedicated professional staff located in Anchorage, Juneau, Fairbanks, and Kenai Fish and Wildlife Offices and the Anchorage Conservation Genetics Laboratory serve as the core of the Program’s fisheries management study efforts. Administrative and technical support is provided by staff in the Anchorage Regional Office. Our program works closely with the Alaska Department of Fish and Game and other partners to conserve and restore Alaska’s fish populations and aquatic habitats. Additional information about the Fisheries Program and work conducted by our field offices can be obtained at: http://alaska.fws.gov/fisheries/index.htm The Alaska Region Fisheries Program reports its study findings through two regional publication series. The Alaska Fisheries Data Series was established to provide timely dissemination of data to local managers and for inclusion in agency databases. The Alaska Fisheries Technical Reports publishes scientific findings from single and multi-year studies that have undergone more extensive peer review and statistical testing.

Plans are published by the National Marine Fisheries Service (NMFS), sometimes prepared with the assistance of recovery teams, contractors, State agencies, and others. Recovery plans do not necessarily represent the views, official positions, or approval of any individuals or agencies involved in the plan formulation, other than NMFS. They represent the official position of NMFS only after they have been signed by the Assistant Administrator. Recovery plans are guidance and planning documents only; identification of an action to be implemented by any public or private party does not create a legal obligation beyond existing legal requirements. Nothing in this plan should be construed as a commitment or requirement that any Federal agency obligate or pay funds in any one fiscal year in excess of appropriations made by Congress for that fiscal year in contravention of the Anti-Deficiency Act, 31 U.S.C. § 1341, or any other law or regulation. Approved recovery plans are subject to modification as dictated by new findings, changes in species status, and the completion of recovery actions.

    Monitoring Juvenile Salmon and Resident Fish within the Matanuska‐Susitna Basin Erin M. Miller, Jeffrey C. Davis, and Gay A. Davis Aquatic Restoration and Research Institute P.O. Box 923, Talkeetna, AK 99676 [email protected] October 2011 National Fish Habitat Action Plan: Juvenile salmon monitoring October 2011 Acknowledgements This project was conducted with partial support from the Mat‐Su Basin Salmon Habitat Partnership under the National Fish Habitat Action Plan. We appreciate the field support provided by Leslie Jensen and Hannah Ramage. 1 National Fish Habitat Action Plan: Juvenile salmon monitoring October 2011 Introduction The sport and commercial salmon harvest is a major component in the economy of Southcentral Alaska and the Matanuska‐Susitna Borough. Salmon abundance depends, in part, on their survival and growth during their fresh‐water residency. Juvenile salmon growth and survival is influenced by the quality and quantity of their fresh water habitat. Public support for the protection of water quality in Alaska is largely through desire to protect commercial and recreational salmon fisheries (TNC 2011). The importance of water quality and physical habitat has been recognized by the Mat‐Su salmon Partnership as a critical component in the strategy for the protection of salmon (Smith and Anderson 2008). Salmon are one of the target indicators of Mat‐Su Salmon Partnership strategic actions; however, the Partnership does not include the abundance of juvenile salmon in evaluating the health of salmon stocks (Smith and Anderson 2008). While water quality and habitat condition are clearly important for rearing juvenile salmon, and salmon production depends, in part, on their growth and survival during fresh‐ water residency, Alaska does not have a monitoring program in place to measure changes in the abundance of rearing juvenile salmon or tools to evaluate differences in salmon abundance to changes in water quality or physical habitat.

For thousands of years the salmon returning to the Inlet’s rivers, lakes and streams have nourished people, wildlife and the land itself. Inhabitants of this region have always had the benefit and pleasure of consuming salmon. Five species of salmon return to spawn in the diverse landscapes of Cook Inlet’s watersheds. The particular habitat required by sockeye salmon is abundant enough to generate Alaska’s second largest sockeye runs. Today there are many natural resources that contribute to the economy of Southcentral Alaska but salmon continue to support traditional subsistence lifestyles, sportfishing enthusiasts and businesses, tourism, commercial fishermen, seafood processors, retailers and supporting industries. While natural wild salmon runs are typically variable and cyclical, some salmon returns to rivers in the Matanuska-Susitna Basin have been in a recent decline. The primary response has been to restrict commercial fisheries in central Cook Inlet with the intent of allowing more salmon to reach the Mat-Su rivers to the north.

    A Comprehensive Inventory of Impaired Anadromous Fish Habitats in the Matanuska-Susitna Basin, with Recommendations for Restoration, 2013 Prepared by ADF&G Habitat Research and Restoration Staff – October 2013 Primary contact: Dean W. Hughes (907) 267-2207 Abstract This document was written to identify the factors or activities that are likely to negatively impact the production of salmonids in the Matanuska-Susitna (Mat-Su) basin and to offer mitigation measures to lessen those impacts. Potential impacts can be characterized in two different catagories; natural and anthropogenic. Natural threats to salmon habitat in the Mat-Su basin include natural loss or alteration of wetland and riparian habitats, alteration of water quality and quantity, and beaver dams blocking fish migration. Anthropogenic impacts include urbanization that increases loss or alteration of wetlands and riparian habitats and decreases water quantity and quality; culverts that block or impair fish passage; ATV impacts to spawning habitats, stream channels, wetlands and riparian habitats; “coffee can” introduction of pike in salmon waters; and, beaver dams at or in culverts. What resulted is an amalgamation of existing research and expertise delivered in a brief narrative describing those limiting factors and activities, as well as an appendix listing possible studies to better understand those impacts and potential projects to limit or repair damage to important salmon habitats (Appendix A). Introduction The Matanuska-Susitna (Mat-Su) Basin is drained primarily by two major rivers, the Matanuska and Susitna. The Susitna River watershed encompasses 19,300 square miles, flowing over 300 miles from the Susitna Glacier in the Alaska Range, through the Talkeetna Mountains, to upper Cook Inlet.

    Parks Highway Road Log

    Bell’s Travel Guides Parks Highway Road Log Mile by Mile Description of the Parks Highway so you always know what lies ahead. Anchorage, Alaska to Fairbanks, Alaska Over twelve years and $150 million went into the completion of this route which extends through 358 miles/576 km of Alaska's most rugged terrain. Yet this highway need not be feared, because it is the state's widest and best year-round road. There are over 40 bridges to cross with the longest being a 1050-foot span of the Susitna River at mile 104. The most spectacular, Hurricane Gulch Bridge, at mile 174.3 is only half the length of the Susitna Bridge, but it is a breathtaking 254 feet above the white water of Hurricane Creek. Denali, the nation's tallest peak, lies about half way between Anchorage and Fairbanks and can be seen from both areas on a clear day: but there's a much better view from mile 70 at Willow. At mile 104 there is a good view of the three tallest peaks in the Alaska Range: Foraker, Hunter and McKinley, left to right. At mile 132.5 you enter Denali State Park. Denali "The Great One" is the Indian name for North America's tallest peak. Perhaps the most spectacular view from the highway of this 20,320-foot mountain comes at mile 134.5. The mileage figures in the following highway description correspond to the numbers appearing on the mileposts in place along most of the highway. The description begins in Anchorage and follows the route's 358 miles to Fairbanks.
