Death to a Deadbeat Dam ADN 08.02.15 (PDF)
Published on Alaska Dispatch News (http://www.adn.com) Home > Death to a deadbeat dam Rick Sinnott [1] August 2, 2015 Main Image: Eklutna River Dam 04 20150723.jpg1437700565 [2] Main Image Caption: Rick Sinnott peers over the lower Eklutna River dam on Thursday, July 23, 2015. The obsolete 61foot high dam, built in 1929, may soon be dismantled, allowing salmon to return to the river. EKLUTNA In 1929, the Eklutna River was dammed, forever it seemed. A 61foothigh dam impounded the river about 1 1/2 miles upstream of the old AnchoragePalmer highway. And few manmade things appear to be as immutable as a concrete dam. On a recent hike through the Eklutna River canyon, slipping on boulders coated with brown algae, wading back and forth between the banks to avoid sheer cliffs or deep pools, I considered what it would be like to be a salmon growing up in such a river. Imagine overwintering as one of thousands of translucent, orange eggs buried in the gravels of riffles or deep pools. Maybe I’d hatch into an alevin, become a fingerling and survive another year or two in the frigid water, constantly alert to predators like rainbow trout and American dippers. One day, with a little luck, I’d become a silvery smolt and swim downstream to Cook Inlet. Only there are no salmon in Eklutna River above the old hydroelectric diversion dam. The dam decimated the river’s salmon runs. If you’re a salmon, however, help is on the way. -

Section 905(B) (WRDA 86) Analysis Eklutna Watershed Study Eklutna, Alaska
Section 905(b) (WRDA 86) Analysis Eklutna Watershed Study Eklutna, Alaska 1. STUDY AUTHORITY This General Investigations study is authorized by the House Public Works Committee Resolution for Rivers and Harbors in Alaska adopted 2 December 1970. The resolution states: Resolved by the Committee on Public Works of the House of Representatives, United States, that the Board of Engineers for River and Harbors is hereby requested to review the report of the Chief of Engineers on Rivers and Harbors in Alaska, published as House Document Number 414, 83d Congress, 2d Session; … and other pertinent reports, with a view to determine whether any modifications of the recommendations contained therein are advisable at the present time. Funding for this section 905(b) Eklutna Watershed Study was established in the 2003 fiscal year Omnibus Appropriations (PL 108-7). 2. STUDY PURPOSE The purpose of this study is to determine whether there is a Federal interest in conducting feasibility level watershed studies of the Eklutna River Watershed. ER 1105-2-100, 22 April 2000 states: “Watershed studies are planning initiatives that have a multi-purpose and multi-objective scope and that accommodate flexibility and collaboration in the formulation and evaluation process. Possible areas of investigation for a watershed study include water supply, natural resource preservation, ecosystem restoration, environmental infrastructure, recreation, navigation, flood management activities, and regional economic development. The outcome of a watershed study will generally be a watershed resources management plan which identifies the combination of recommended actions to be undertaken by various partners and stakeholders in order to achieve the needs and opportunities identified in the study.” A Federal interest in the resolution of identified water resource problems is contingent upon there being probable environmentally acceptable and technically feasible solutions to identified water resources problems. -

Chapter 4 Hazards in Anchorage
Anchorage All-Hazard Mitigation Plan October 2004 CHAPTER 4 HAZARDS IN ANCHORAGE One of the requirements of a hazard mitigation plan is that is describes the hazards that affect a jurisdiction. This chapter profiles the hazards that occur in Anchorage by identifying each hazard’s location, extent, previous occurrences, and the probability of future events. Hazard mitigation plans are also required to summarize the vulnerability to the hazards. The vulnerability information was calculated by identifying the parcels that intersect each of the hazard zones. Some notes about this method are: • Not all the hazard GIS layers used to perform this analysis cover the entire MOA. Most only include a portion of the Municipality. (Parcels could be at risk but the risk area has not been mapped and included in the GIS yet.) • The taxable value is based on 2003 MOA tax assessor data • Using the taxable Value underestimates the vulnerability because: - Some parcels, such as schools, are not taxed and therefore do not have a taxable value. - Some parcels are treated as economic units (separate parcels that are treated as 1 for tax purposes) and do not have taxable values listed. - Taxable value does not consider the value of the contents. - The taxable value is the sum on the land and building taxable values. This is different from the total taxable value listed in the tax assessor’s file because tax exemptions have been applied to those totals. • If a parcel was in multiple risk areas, the entire parcel was considered to be in the highest risk area (i.e., no partial parcels). -
2018 HCD Accomplishments Report
Alaska Region Habitat Conservation Division Fiscal Year 2018 Accomplishments Figure 1. Atka Mackerel from the Aleutian Islands Bottom Trawl Survey in July 2018. Photo: Sam Simpson Habitat conservation, protection, and restoration are the foundation for sustaining the nation’s fisheries. The Alaska Region Habitat Conservation Division (HCD) carries out the National Marine Fisheries Service’s (NMFS) statutory responsibilities for habitat conservation in Alaska under the Magnuson-Stevens Fishery Conservation and Management Act (MSA), the Fish and Wildlife Coordination Act (FWCA), the National Environmental Policy Act (NEPA), the Federal Power Act (FPA), and other laws. To prioritize our resources and activities, make decisions in an ecosystem context, and strengthen the science behind our decision-making, HCD works closely with the Alaska Fisheries Science Center (AFSC), other NOAA line offices, the North Pacific Fishery Management Council (NPFMC), other federal and state agencies, non-governmental organizations, local governments, and a variety of industry and conservation groups. By leveraging these partnerships, we work together to better execute the Alaska Region’s mission: the science-based stewardship of living marine resources and their habitat in the waters of the North Pacific and Arctic Oceans off Alaska. The Alaska Region’s mission responsibilities include supporting sustainable fisheries, recovering and conserving protected species, and promoting healthy ecosystems and resilient coastal communities This report highlights HCD’s accomplishments for Fiscal Year 2018, from October 1, 2017 through September 30, 2018. We have restructured the format of this Report to reflect our commitment to HCD’s six overarching goals. 1 Contents Goal #1: Identify and pursue opportunities to conserve and restore marine and anadromous water habitats. -

Herbert Hoover Dike: Past, Present and Future Page 8
SPRING 2018 | ISSUE NO. 174 Bulletin of the United States Society on Dams Herbert Hoover Dike: Past, Present and Future Page 8 USSD 2018 Facing the Collaboration History of 5 Annual 16 Challenges of 19 and Rigorous 28 Pathfinder Dam Conference and Dam Removal in Science Required Exhibition Alaska to Address Changing Needs www.ussdams.org Brad Meiklejohn, Alaska State Director, The Conservation Fund, Anchorage, Alaska ([email protected]) FEATURE Facing the Challenges of Dam Removal in Alaska he Conservation Fund has nearly T completed the demolition of the long- abandoned Lower Eklutna Dam, near the native village of Eklutna, Alaska. The Lower Eklutna River Dam Removal Project is the most ambitious river restoration project ever attempted in Alaska. The Lower Eklutna Dam was built in 1928 as part of Alaska’s first hydroelectric project. Located in a dramatic 400-foot deep canyon, access to the dam site was a severe challenge during the construction (and demolition) of the dam. In construction, a tram cart delivered concrete down the cliff face to the workers below. This hardy crew worked throughout an entire Alaskan winter to complete the dam in a year’s time. The dam itself was a concrete arch whose dimensions were 70 feet wide, 100 feet tall and 9 feet thick at the dam base. This structure pooled and diverted water through a half- mile tunnel to a generating station nearby. Power ran by wire twenty miles south to Anchorage, providing the first reliable supply of electricity to this frontier settlement. The Lower Eklutna River Dam. Lower Eklutna power project operated until the early 1950s when it was decommissioned and ultimately abandoned.
