Ground Water in the Anchorage Area, Alaska Meeting the Challenges of Ground-Water Sustainability Ground Water in the Anchorage Area, Alaska Meeting the Challenges of Ground-Water Sustainability Present and projected water use Ground water is an important component of Anchorage’s water supply. During the 1970s and early 80s when ground water extracted from aquifers near Ship Creek was Anchorage Water and Wastewater the principal source of supply, area-wide declines in ground-water levels resulted Utility (AWWU) provides locally obtained in near record low streamflows in Ship Creek. Since the importation of Eklutna Lake surface water and ground water to satisfy water in the late 1980s, ground-water use has been reduced and ground water has most of the city’s public water demand. contributed 14– 30 percent of the annual supply.

  • Introduc Tion
    1 INTRODUCTION SHIP CREEK FRAMEWORK PLAN INTRODUCTION This Framework Plan proposes a long-term vision for the future evolution of the Ship Creek area of Anchorage, including downtown Anchorage and the Cook Inlet waterfront. In its 100 year history the Municipality of Anchorage has evolved from a tent city to a major metropolitan center and transportation hub on the Pacific rim. This Plan will guide future development of the original site of Anchorage, Ship Creek for the next century of growth and evolution, and when fully implemented will create something that Anchorage has never had: A truly accessible and public waterfront. Anchorage is the only major US city on a large body of water without such a waterfront, and given the spectacular natural setting that Anchorage enjoys and the immediate access to its surrounding natural areas, giving the public an attractive and accessible Cook Inlet waterfront this is the logical next step in the city’s development. As newer generations of Americans migrate back to our cities’ centers seeking a more urban and sustainable lifestyle, this waterfront will add tremendous value to Anchorage’s downtown, Anchorage aerial photograph further stimulating investment and development. 2. The economy is strengthening. Recovery from the “great What do people want? The Framework Plan shares many of the same goals and makes many recession” is underway. The Alaskan economy is growing, This Ship Creek Framework Plan is the result of hundreds of hours of of the same recommendations as the 1991 Ship Creek/Waterfront Land unemployment is down and the energy sector is expanding in stakeholder involvement over a six month period.

  • Anchorage Area Fishing Opportunities
    Southcentral Region Department of Fish and Game Anchorage Area Fishing Opportunities Anchorage Area The Anchorage area includes all lakes and streams from Eklutna River (northern boundary) to Ingram Creek in Turnagain Arm (southern boundary). Anchorage is unique in the sport fishing world. Anglers can catch 20- to 30-pound king salmon and 8- to 10-pound silver salmon right in town. There’s also excellent fishing for rainbow trout, Dolly Varden char, and Arctic grayling in area lakes and streams. The majority of Anchorage-area sport fishing is the result of hatchery stockings. Though many streams within the Anchorage area support natural runs of one or all of the five Pacific salmon species, most of these native runs are too small to support sport fisheries. Check your regulation book carefully, or look at the changes, called emergency orders, primarily in quick guide on Page 7 of this handout, since many area response to under- or over-abundance of fish. flowing waters are closed to salmon fishing.
