What can these restoration stories tell us? GIS In this paper, we examine the effects of dams along the Penobscot River in Maine (USA) on residential property values. We compare the results to findings from a similar (but ex post dam removal) data set for properties along the Kennebec river in Maine, where the Edwards Dam was removed in 1999. -

Final Environmental Impact Statement
Final Environmental Impact Statement Elwha River Ecosystem Restoration Implementation Purpose and Need: The Elwha River ecosystem and native anadromous fisheries are severely degraded as a result of two hydroelectric dams (projects) and their reservoirs built in the early 1900s. Congress has mandated the full restoration of this ecosystem and its native anadromous fisheries through the Elwha River Ecosystem and Fisheries Restoration Act (Public Law 102-495). The Department of the Interior has found there is a need to return this river and the ecosystem to its natural, self-regulating state, and proposes to implement the Congressional mandate by removing both dams in a safe, environmentally sound and cost effective manner and implementing fisheries and ecosystem restoration planning. Only dam removal would fully restore the ecosystem or its native anadromous fisheries. Proposed Action: The U.S. Department of the Interior proposes to fully restore the Elwha River ecosystem and native anadromous fisheries through the removal of Elwha Dam and Glines Canyon Dam and implementing fish restoration and revegetation. Dam removal would occur over a 2-year period. Elwha Dam would be removed by blasting, and Glines Canyon Dam by a combination of blasting and diamond wire saw cutting. Lake Aldwell would be drained by a diversion channel, and Lake Mills by notching down Glines Canyon Dam. Stored sediment would be eroded naturally by the Elwha River. The proposed action is located in Clallam County, on the Olympic Peninsula, in Washington State. Lead/Cooperating agencies: The National Park Service is the lead agency.

2016 State of Our Watersheds Report West WRIA 18 – Morse Creek to Elwha River
2016 State of Our Watersheds Report West WRIA 18 – Morse Creek to Elwha River am removal seemed like an elusive Dtarget over the years and many citizens were skeptical of the benefits. However in just four years the river has transported over 60% of the stored sediment, resulting in a rebirth of the estuary and the floodplain. Salmon are ascending to historic habitats and the recovery of the ecosystem is about to blossom. -MIkE MCHENrY FIsHErIEs HABItAt MANAGEr Lower Elwha Klallam Tribe The Lower Elwha Klallam Tribe is part of the Klal- lam Band of Indians that have resided throughout the Strait of Juan de Fuca, Hood Canal and Port Gamble Bay for generations. They are party to the Point No Point Treaty of 1855, when tribes ceded most their traditional lands to the U.S. government. The Dunge- ness-Elwha Basin (WRIA 18) has remained largely Seattle rural and forested with a natural resources-based economy focused on shellfish harvesting, commercial forestry, commercial fisheries, tourism, and agricul- ture. Major land-use impacts on salmon habitat have occurred from floodplain and shoreline development, road construction and past logging practices. This report will focus on the northwest portion of WRIA 18 basin and surrounding marine waters, which is only a portion of the area that the Lower Elwha Klallam Tribe co-manages. 58 Lower Elwha Klallam Tribe Elwha Basin The Area of Concern for the Lower Elwha Klallam Tribe (Elwha shoreline habitat conditions.

Item F – Klamath Dam Removal - Contingency Funding March 9-10, 2021 Board Meeting
Kate Brown, Governor 775 Summer Street NE, Suite 360 Salem OR 97301-1290 www.oregon.gov/oweb (503) 986-0178 Agenda Item F supports OWEB’s Strategic Plan priority #3: Community capacity and strategic partnerships achieve healthy watersheds, and Strategic Plan priority 7: Bold and innovative actions to achieve health in Oregon’s watersheds. MEMORANDUM TO: Oregon Watershed Enhancement Board FROM: Meta Loftsgaarden, OWEB Executive Director Richard Whitman, DEQ Director SUBJECT: Agenda Item F – Klamath Dam Removal - Contingency Funding March 9-10, 2021 Board Meeting I. Introduction Removal of the four PacifiCorp dams along the Klamath River in Oregon and California that block fish passage has been a priority of multiple governors in both states for over a decade. After extensive work by the Klamath River Renewal Corporation and its contractors (in partnership with states, tribes, federal agencies, irrigators, conservation groups, and many others), there is now a clear path to completing dam removal in 2023. This staff report updates the board on the dam removal project and asks for a general indication of board support in the unlikely event that additional funding is needed to complete restoration work following dam removal. II. Background PacifiCorp owns and operates four hydro-electric dams on the Klamath River, three in California and one in Oregon. PacifiCorp has decided to that it is in the best interest of the company and its customers to stop operating the dams rather than spending substantial amounts on improvements likely to be needed if they were to continue generating power. PacifiCorp has agreed to transfer ownership of the dams to the Klamath River Restoration Corporation, which in turn has contracted with Kiewit Infrastructure -- one of the nation’s most experienced large project construction firms – which will remove the dams and restore the river to a free-flowing condition. -

Effects of the Glen Canyon Dam on Colorado River Temperature Dynamics
Effects of the Glen Canyon Dam on Colorado River Temperature Dynamics GEL 230 – Ecogeomorphology University of California, Davis Derek Roberts March 2nd, 2016 Abstract: At the upstream end of the Grand Canyon, the Glen Canyon Dam has changed the Colorado River from a run-of-the-river flow to a deep, summer-stratified reservoir. This change in flow regime significantly alters the temperature regime of the Colorado River. Seasonal temperature variation, once ranging from near to almost , is now limited to 7 . The lack of warm summer temperatures has prevented spawning of endangered 0℃ 30℃ humpback chub in the Colorado River. Implementation of a temperature control device, to − 14℃ allow for warmer summer releases to mitigate negative temperature effects on endangered fish, was considered by the federal government. Ultimately, this proposal was put on indefinite hold by the Bureau of Reclamation and U.S. Fish and Wildlife Service due to concerns of cost and unintended ecological consequences. The low-variability of the current dam-induced Colorado River temperature regime will continue into the foreseeable future. Agencies are reviewing humpback chub conservation efforts outside of temperature control. Keywords: Colorado River, Grand Canyon, Glen Canyon Dam, thermal dynamics 1.0 Introduction Temperature in natural water bodies is a primary driver of both ecological and physical processes. Freshwater plant and animal metabolisms are heavily affected by temperature (Coulter 2014). Furthermore, the thermal structure of a water body has significant impacts on the physical processes that drive ecosystem function (Hodges et al 2000); fluid dynamics drive transport of nutrients, oxygen, and heat. Human action, often the introduction of dams or industrial cooling systems, can alter the natural thermal regimes of rivers and lakes leading to reverberating impacts throughout associated ecosystems.
