Fate and Behavior of Rotenone in Diamond Lake, Oregon, Usa Following Invasive Tui Chub Eradication
Environmental Toxicology and Chemistry, Vol. 33, No. 7, pp. 1650–1655, 2014 # 2014 SETAC Printed in the USA FATE AND BEHAVIOR OF ROTENONE IN DIAMOND LAKE, OREGON, USA FOLLOWING INVASIVE TUI CHUB ERADICATION BRIAN J.

HUCHKOx yCalifornia Department of Fish and Game (retired), Rancho Cordova, California, USA zMaxDepth Aquatics, Bend, Oregon, USA xOregon Department of Fish and Wildlife, Roseburg, Oregon, USA (Submitted 5 August 2013; Returned for Revision 15 September 2013; Accepted 7 April 2014) Abstract: In September 2006, Diamond Lake (OR, USA) was treated by the Oregon Department of Fish and Wildlife with a mixture of powdered and liquid rotenone in the successful eradication of invasive tui chub Gila bicolor. During treatment, the lake was in the middle of a phytoplankton (including cyanobacteria Anabaena sp.) bloom, resulting in an elevated pH of 9.7. Dissipation of rotenone and its major metabolite rotenolone from water, sediment, and macrophytes was monitored. Rotenone dissipated quickly from Diamond Lake water; fi approximately 75% was gone within 2 d, and the average half-life (t1/2) value, estimated by using rst-order kinetics, was 4.5 d. Rotenolone > persisted longer ( 46 d) with a short-term t1/2 value of 16.2 d. Neither compound was found in groundwater, sediments, or macrophytes. The dissipation of rotenone and rotenolone appeared to occur in 2 stages, which was possibly the result of a release of both compounds from decaying phytoplankton following their initial dissipation. Fisheries managers applying rotenone for fish eradication in lentic environments should consider the following to maximize efficacy and regulatory compliance: 1) treat at a minimum of twice the minimum dose demonstrated for complete mortality of the target species and possibly higher depending on the site’s water pH and algae abundance, and 2) implement a program that closely monitors rotenone concentrations in the posttreatment management of a treated water body. -

Overview for Geologic Field-Trip Guides to Mount Mazama, Crater Lake Caldera, and Newberry Volcano, Oregon
Overview for Geologic Field-Trip Guides to Mount Mazama, Crater Lake Caldera, and Newberry Volcano, Oregon Scientific Investigations Report 2017–5022–J U.S. Department of the Interior U.S. Geological Survey Cover (top photo): View east-northeast from Garfield Peak on the south rim of Crater Lake caldera. Peak on skyline is 8,929 feet (2,722 meters) Mount Scott, an ~420 thousand years before present (ka) dacite stratovolcano considered to be part of Mount Mazama, the volcano that collapsed during the caldera-forming eruption ~7,700 years ago. The caldera walls in this view expose Mazama lava flows and fragmental deposits from as old as ~400 ka at Phantom Cone, adjacent to tiny Phantom Ship island, to as young as ~27 ka at Redcloud Cliff, the V-shaped face at the top of the wall left of center. The beheaded glacial valley of Kerr Notch, the low point on the caldera rim, is seen between Phantom Ship and Mount Scott. Photograph by Carly McLanahan. Cover (bottom photo): Newberry Volcano, Oregon, is the largest volcano in the Cascades volcanic arc. This north-facing view taken from the volcano’s peak, Paulina Peak (elevation 7,984 feet), encompasses much of the volcano’s 4-by-5-milewide central caldera, a volcanic depression formed in a powerful explosive eruption about 75,000 years ago. The caldera’s two lakes, Paulina Lake (left) and the slightly higher East Lake (right), are fed in part by active hot springs heated by molten rock (magma) deep beneath the caldera. The Central Pumice Cone sits between the lakes. -
Fifteenmile Subbasin Plan
Fifteenmile Subbasin Plan DRAFT May 25, 2004 Prepared by Wasco County Soil and Water Conservation District and Fifteenmile Coordinating Group for The Northwest Power and Conservation Council Fifteenmile Subbasin Plan Table of Contents Section 1: Executive Summary Section 2: Introduction Section 3: Assessment Section 4: Inventory of Existing Activities Section 5: Management Plan Section 6: Appendices A through J Fifteenmile Subbasin Plan DRAFT May 25 2004 Wasco County Soil and Water Conservation District, in cooperation with Fifteenmile Coordinating Group 1. Executive Summary The Fifteenmile Subbasin Plan has been developed as part of the Northwest Power and Conservation Council’s Columbia River Basin Fish and Wildlife Program. Subbasin plans will be reviewed and eventually adopted into the Council’s Fish and Wildlife Program to help direct Bonneville Power Administration (Bonneville) funding of projects that protect, mitigate and enhance fish and wildlife habitats adversely impacted by the development and operation of the Columbia River hydropower system. The National Oceanic and Atmospheric Administration (NOAA) Fisheries, and the U.S. Fish and Wildlife Service (USFWS) intend to use subbasin plans as building blocks in recovery planning to meet the some of their requirements of the 2000 Federal Columbia River Power System Biological Opinion (BiOp). Subbasin planning through the Council’s program will also assist Bonneville with some of the requirements they have under the 2000 BiOp. The Fifteenmile Coordinating Group intends the Fifteenmile Subbasin Plan to serve multiple purposes. The Group intends the plan to meet the Council’s call for subbasin plans as part of its Columbia Basin wide program and to provide a resource for all entities involved with natural resource planning efforts. -

Introduction to Crater Lake
National Park Service Crater Lake U.S. Department of the Interior Crater Lake National Park Introduction to Crater Lake Crater Lake Is Like No Crater Lake has inspired its visitors for hundreds of years. No place else on earth Place Else On Earth combines such a deep, pure lake with sheer surrounding cliffs and a violent volcanic past. Few places on earth are so beautiful, so pristine, or—for these very reasons—so interesting to scientists. An Introduction to Crater Lake is located in Southern Oregon on the Following the collapse of Mount Mazama, lava Crater Lake crest of the Cascade Mountain range, 100 miles poured into the caldera even as the lake began to (160 km) east of the Pacific Ocean. It lies inside a rise. Today, a small volcanic island, Wizard Island, caldera, or volcanic basin, created when the 12,000 appears on the west side of the lake.

USGS Scientific Investigations Map 2832, Pamphlet
Geologic Map of Mount Mazama and Crater Lake Caldera, Oregon By Charles R. Bacon Pamphlet to accompany Scientific Investigations Map 2832 View from the south-southwest rim of Crater Lake caldera showing the caldera wall from Hillman Peak on the west to Cleetwood Cove on the north. Crater Lake fills half of the 8- by 10-km-diameter caldera formed during the climactic eruption of Mount Mazama volcano approximately 7,700 years ago. Volcanic rocks exposed in the caldera walls and on the flanks record over 400,000 years of eruptive history. The exposed cinder cone and andesite lava flows on Wizard Island represent only 2 percent of the total volume of postcaldera volcanic rock that is largely covered by Crater Lake. Beyond Wizard Island, the great cliff of Llao Rock, rhyodacite lava emplaced 100–200 years before the caldera-forming eruption, dominates the northwest caldera wall where andesite lava flows at the lakeshore are approximately 150,000 years old. 2008 U.S. Department of the Interior U.S. Geological Survey This page intentionally left blank.

The new members to Historic Hotels of America are located in the following National Parks: Grand Canyon National Park, Crater Lake National Park, Yellowstone National Park, Zion National Park, and Death Valley National Park. Historic Hotels of America welcomes Phantom Ranch, Bright Angel Lodge and Cabins, and El Tovar from Grand Canyon National Park. Bright Angel Lodge was listed in the National Register of Historic Places in 1982, features great panoramic vistas, and is known to be the hub of the South Rim. El Tovar was listed in the National Register of Historic Places in 1974 and on May 28, 1987, El Tovar was designated by the U.S. Secretary of the Interior as a National Historic Landmark. Phantom Ranch, built in 1922, on the north side of the Colorado River is the only lodging facility located below the canyon rim. Zion Lodge in Zion National Park is also a newly appointed member of Historic Hotels of America. Zion Lodge was listed in the National Register of Historic Places in 1987. -
