White sturgeon mitigation and restoration in the Columbia and Snake rivers upstream from Bonneville Dam Report C, Annual Progress Report April 2003 - March 2004

River discharge and water temperatures that occurred during April through July 2003 provided conditions suitable for spawning by white sturgeon downstream from Bonneville, The Dalles, John Day, and McNary dams. Although optimal spawning temperatures in the four tailraces occurred for less than two weeks, they coincided with a period of relatively high river discharge. Bottom-trawl sampling in Bonneville and The Dalles Reservoirs revealed the presence of young-of-the-year (YOY) white sturgeon in Bonneville Reservoir, but none were captured in The Dalles Reservoir. A comparison of five years of indices of abundance of YOY sturgeon from sampling done by ODFW with gillnets and the USGS with bottom trawls was completed. Despite obvious differences in gear sampling characteristics (e.g. one gear is actively fished, one passively fished), it appears that either gear can be used to assess relative trends in YOY white sturgeon abundance. The analyses suffered due to poor catches of YOY fish, as YOY were only captured in The Dalles Reservoir during three of the five years of comparison sampling, and during only one of four years in John Day Reservoir. However, both gears detected the presence or absence of YOY white sturgeon within a reservoir equally. That is, if any YOY white sturgeon were captured in any year in a reservoir, both gears captured at least one fish, and if one gear failed to collect any YOY white sturgeon, both gears failed. Concerns have been raised that the Wang et al. (1985) egg development relationships for Sacramento River white sturgeon may not be applicable to Columbia Basin stocks. However, using laboratory experiments with white sturgeon eggs incubated at 10, 12, 15, and 18o C, we found no significant differences in development rates of eggs of Columbia, Kootenai, Snake, and Sacramento river fish.

White sturgeon mitigation and restoration in the Columbia and Snake rivers upstream from Bonneville Dam, Annual Progress Report April 2004 - March 2005. Report C

River discharge and water temperatures that occurred during April through July 2004 provided conditions suitable for spawning by white sturgeon downstream from Bonneville, The Dalles, John Day, and McNary dams. Optimal spawning temperatures in the four tailraces occurred for 3-4 weeks and coincided with the peak of the river hydrograph. However, the peak of the hydrograph was relatively low compared to past years, which is reflected in the relatively low monthly and annual indices of suitable spawning habitat. Bottom-trawl sampling in the Bonneville Reservoir revealed the presence of young-of-theyear (YOY) white sturgeon.

White sturgeon mitigation and restoration in the Columbia and Snake rivers upstream from Bonneville Dam, Annual Progress Report April 2005 - March 2006. Report C.

River discharge and water temperatures that occurred during April through July 2005 provided conditions suitable for spawning by white sturgeon downstream from Bonneville, The Dalles, John Day, and McNary dams. Optimal spawning temperatures in the four tailraces occurred for 3-4 weeks and coincided with the peak of the river hydrograph. However, the peak of the hydrograph occurred in mid May and discharges dropped quickly and water temperature rose during June, which is reflected in the monthly and annual indices of suitable spawning habitat. Indices of available spawning habitat for the month of June 2005 were less than one-half of the average of the period from 1985-2004. Bottom-trawl sampling in the Bonneville Reservoir revealed the presence of young-of-the-year (YOY) white sturgeon but the proportion of positive tows was quite low at 0.06.

Hydrology of subsurface waste disposal, National Reactor Testing Station, Idaho: Annual progress report for 1964

The principal purpose of the past research program on geohydrology at the NRTS has been to acquire information on the physical and geochemical environment of the station. This requires a knowledge of the composition and structure of the earth materials underlying the plain, the inventory of the water resources, the dynamics of natural and man-produced changes in the hydrologic regimen, details of the hydrologic cycle, and relevant geochemical processes. The Geological Survey in the course of its early studies by Nace and others (IDO 22033-34-USGS) obtained, compiled, and analyzed a considerable amount of basic geologic and hydrologic information on these subjects. These basic goals were expanded and carried forward to guide the continuing research work. Jones (IDO 22042-USGS) emphasized the use of borehole geophysics and specialized down-hole techniques. Olmsted (IDO 22043-USGS) made a preliminary appraisal of the nature and distribution of the quality of ground water beneath the Station. Their work has been continued and elaborated upon by Morris and others (IDO 22044-USGS, 46-USGS) and the present report with greater emphasis on the regional geology and hydrology. This involved some procurement of needed information but, for the most part, involved a continued evaluation and refinement of data and results that had been acquired in the past. The Geological Survey also encouraged a more comprehensive study of the regional geologic structure including the use of aeromagnetic, gravity, and seismic geophysical techniques and cosponsored a seminar on it in 1964. Along with this investigation and study of the regional geology and of hydrologic principles operative in the basalt environment, and made possible because of it, research continues on the-hydrologic aspects of the disposal of low-level aqueous waste to the environment.

2004 annual progress report: Stratton Sagebrush Hydrology Study Area: Establishment of a long-term research site in a high-elevation sagebrush steppe

In 2004 the U.S. Geological Survey, Fort Collins Science Center (FORT) and the Bureau of Land Management (BLM), Rawlins Field Office (RFO), began a cooperative effort to reestablish the Stratton Sagebrush Hydrology Study Area (Stratton) as a research location, with the goal of making it a site for long-term research on sagebrush (Artemisia spp.) ecology. No other long-term research sites in high-elevation sagebrush habitat currently exist, and the Stratton area, with its 30+ year history of research and baseline data, was a logical location to restart investigations aimed at answering pertinent and timely questions about sagebrush ecology and sagebrush-obligate species. During the first year of the study, USGS scientists conducted an in-depth literature search to locate publications from research conducted at Stratton. We contacted previous researchers to acquire literature and unpublished reports of work conducted at Stratton. Collated papers and published manuscripts were presented in an annotated bibliography (Burgess and Schoenecker, 2004). A second goal was to establish Stratton as a host location for researchers interested in sagebrush ecology investigations. We contacted staff and professors from Colorado State University and Wyoming and Montana universities to notify them of the opportunities at Stratton. Several institutions showed interest in the area and the potential of such a research site. A major advantage of the Stratton site is the ability of BLM to coordinate activities on the land, manipulate grazing in cooperation with permit holders, and direct other activities to accommodate appropriate long-term experimental designs. A third goal was to evaluate grazing management after a prescribed burn. The BLM widely uses prescribed burns as a tool for land management and grazing management. In general, BLM policy restricts grazing after a wildfire for two or more years. Some BLM offices allow no grazing after a wildfire or prescribed treatment for at least two years. Conversely, the RFO often allows grazing following a prescribed burn directly after the peak growing season the following year. This procedure is used for two years post-burn, after which grazing management is directed by local conditions and goals. We are investigating this practice to evaluate the effects on plant production and nutrient cycling. The RFO specifically wants to know if there are negative effects from grazing one season after a prescribed burn.

2005 annual progress report: Elk and bison grazing ecology in the Great Sand Dunes complex of lands

In 2000 the U.S. Congress authorized the expansion of the former Great Sand Dunes National Monument by establishing a new Great Sand Dunes National Park and Preserve in its place, and establishing the Baca National Wildlife Refuge. The establishment of Great Sand Dunes National Park and Preserve and the new Baca National Wildlife Refuge in the San Luis Valley (SLV), Colorado was one of the most significant land conservation actions in the western U.S. in recent years. The action was a result of cooperation between the National Park Service (NPS), U.S. Fish and Wildlife Service (USFWS), Bureau of Land Management (BLM), U.S. Forest Service (USDA-FS), and The Nature Conservancy (TNC). The new national park, when fully implemented, will consist of 107,265 acres, the new national preserve 41,872 acres, and the new national wildlife refuge (USFWS lands) 92,180 acres (fig. 1). The area encompassed by this designation protects a number of natural wonders and features including a unique ecosystem of natural sand dunes, the entire watershed of surface and groundwaters that are necessary to preserve and recharge the dunes and adjacent wetlands, a unique stunted forest, and other valuable riparian vegetation communities that support a host of associated wildlife and bird species. When the National Park was initially established, there were concerns about overconcentrations and impacts on native plant communities of the unhunted segments of a large and possibly growing elk (Cervus elaphus) population. This led to the designation of the Preserve as a compromise solution, where the elk could be harvested. The Preserve Unit, however, will not address all the ungulate management challenges. In order to reduce the current elk population, harvests of elk may need to be aggressive. But aggressive special hunts of elk to achieve population reductions can result in elk avoidance of certain areas or elk seeking refuge in areas where they cannot be hunted, while removals of whole herd segments and abandonment or alterations of migration routes can occur (Smith and Robbins, 1994; Boyce and others, 1991). Elk may seek refuge from hunting in the newly expanded Park Unit and TNC lands where they might overconcentrate and impact unique vegetation communities. In these sites of refugia, or preferred loafing sites, elk and bison could accelerate a decline in woody riparian shrubs and trees. This decline may also be due to changes in hydrology, climatic, or dunal processes, but ungulate herbivory might exacerbate the effects of those processes. To address the questions and needs of local resource managers, a multi-agency research project was initiated in 2005 to study the ecology, forage relations, and habitat relations of elk and bison in the Great Sand Dunes–Sangre de Cristo–Baca complex of lands. Meetings and discussions of what this research should include were started in 2001 with representatives from NPS, USFWS, TNC, the Colorado Division of Wildlife (CDOW), and USDA-FS/BLM. The final study plan was successfully funded in 2004 with research scheduled to start in 2005. The research was designed to encompass three major study elements: (1) animal movements and population dynamics, (2) vegetation and nutrient effects from ungulate herbivory, and (3) development of ecological models, using empirical data collected from the first two components, that will include estimates of elk carrying capacity and management scenarios for resource managers.

Astrogeologic studies, annual progress report, August 25, 1961 - August 24, 1962

This report, which covers the period August 25, 1961 to August 24, 1962, is the third of a series describing the program of research conducted by the U.S. Geological Survey on behalf of the National Aeronautics and Space Administration. The major long-range objectives of the program are to determine and map the stratigraphy and structure of the Moon's crust, to work out from these the sequence of events that led to the present condition of the Moon's surface, and to determine the processes by which these events took place. This report is presented in four parts with a separate summary. Part A: Lunar and planetary investigations (with map supplement). Geologic mapping of the Moon involves discrimination of the different materials exposed on the lunar surface and their assignment to geologic units, the determination of the photometric characteristics of these materials, delineation of the boundaries of the units and determination of their stratigraphic sequence. Part B: Crater investigations. These include field studies of terrestrial craters, hypervelocity impact experiments with rocks and other materials, studies of the behavior of rocks under high shock loads, and experimental and field studies of shock metamorphism in rocks. Part C: Cosmochemistry and petrography. Studies are being made of the chemical, petrographic, and physical properties of materials of extraterrestrial origin and of certain materials associated with terrestrial impact structures. The studies reported in Part C are concerned with tektites, terrestrial impactites, metallic spherules formed by the Meteor Crater impact event, and particles of possible cosmic origin. Part D: Studies for space flight program. These studies are undertaken to aid in the design of space flight experiments and the planning of space missions. The report that makes up Part D is an evaluation of the lunar flux of secondary particles derived from primary impact events on the lunar surface.

Geochemical survey of the western coal regions; first annual progress report, July 1974

National energy needs have precipitated an increased interest in the development of a large coal-based electric power industry in the western United States. This anticipated development has, in turn, spawned a great deal of interest in the environmental impact consequent upon the mining and utilization of these coal supplies. Numerous studies directed to assessing this impact are underway or are in the planning stages by agencies of government at all levels as well as by educational institutions and private firms. It is expected that such studies will continue to increase in number in the foreseeable future. Some idea of the diversity of this work is given by Boulding (1974), who surveyed a broad spectrum of people and organizations concerned about the environmental impact of coal development in the Northern Great Plains. This survey included over 50 governmental organizations and over 50 nongovernmental organizations.

Evaluation of fisher (Pekania pennanti) restoration in Olympic National Park and the Olympic Recovery Area: 2014 annual progress report

With the translocation and release of 90 fishers ( Pekania pennanti ) from British Columbia to Olympic National Park during 2008–2010, the National Park Service and Washington Department of Fish and Wildlife accomplished the first phase of fisher restoration in Washington State. Beginning in 2013, we initiated a new research project to determine the current status of fishers on Washington’s Olympic Peninsula 3–5 years after the releases and evaluate the short-term success of the restoration program. Objectives of the study are to determine the current distribution of fishers and proportion of the recovery area that is currently occupied by fishers, determine several genetic characteristics of the reintroduced population, and determine reproductive success of the founding animals through genetic studies. During 2014, we continued working with a broad coalition of cooperating agencies, tribes, and nongovernmental organizations (NGO) to collect data on fisher distribution and genetics using noninvasive sampling methods. The primary sampling frame consisted of 157 24-square-kilometer hexagons (hexes) distributed across all major land ownerships within the Olympic Peninsula target survey area. In 2014 we expanded the study by adding 58 more hexes to an expanded study area in response to incidental fisher observations outside of the target area obtained in 2013; 49 hexes were added south and 9 to the east of the target area. During 2014, federal, state, tribal and NGO biologists and volunteers established three baited motion-sensing camera stations, paired with hair snaring devices, in 80 hexes; 69 in the targeted area 11 in the expansion areas. Each paired camera/hair station was left in place for approximately 6 weeks, with three checks on 2-week intervals. We documented fisher presence in 5 of the 80 hexagons, and identified 5 different fishers through a combination of microsatellite DNA analyses and camera detections. All fisher detections were in the target area. These 5 individuals included 2 of the original founding population of 90, 1 of the 2 rescued and rehabilitated kits that were released in 2010, and 1 new recruit to the population (1 individual was not identified). Additionally, we identified more than 40 other species of wildlife at the baited camera stations. We also obtained eight incidental fisher observations through photographs and carcass retrieval. During 2015, we plan to sample 75 hexagons in the target area and 12 in the expansion area. We plan to sample all unsampled accessible hexes in the target area (26 hexes), and re-sample accessible hexes sampled in 2013 (49 hexes).

White sturgeon mitigation and restoration in the Columbia and Snake rivers upstream from Bonneville Dam, Annual progress report April 2002 - March 2003. Report C

During 1 April 2002 through 31 March 2003, the U.S. Geological Survey (USGS) continued work on several tasks, including quantifying habitat suitable for white sturgeon Acipenser transmontanus spawning, a long-term survey of young-of-the-year (YOY) white sturgeon recruitment in the lower Columbia River, and a laboratory study investigating predation on larval and juvenile white sturgeon. River discharge and water temperatures that occurred during April through July 2002 provided relatively good conditions for spawning by white sturgeon downstream from Bonneville, The Dalles, John Day, and McNary dams. Optimal spawning temperatures in the four tailraces occurred for approximately three weeks and during a period of relatively high river discharge. Our monthly estimates of the index of spawning habitat showed that the availability of habitat for spawning peaked in June at levels higher than the average of past years. However, indices for the month of May were less than average in all four tailraces. YOY white sturgeon were collected during bottom trawling in Bonneville and The Dalles reservoirs, but none were captured in the John Day Reservoir. In an ongoing comparison of indices of abundance derived from bottom trawls and gill nets, the Oregon Department of Fish and Wildlife also caught YOY white sturgeon in gill nets set in The Dalles Reservoir, but none in the John Day Reservoir. The third year of a three-year laboratory predation study was completed. Adult channel catfish ingested white sturgeon up to a mean total length of about 120 mm, and juvenile walleye ate white sturgeon up to a mean length of 53 mm. When white sturgeon and coho salmon were both available as prey, northern pikeminnow continued to ingest white sturgeon, but in most cases preferred salmon. Conversely, prickly sculpins preferred white sturgeon over goldfish as prey. The presence of cover and also lower light levels reduced predation by sculpins on white sturgeon larvae, but cover did not reduce predation on white sturgeon juveniles. Similar to the past two years, turbidity affected predation of white sturgeon larvae by prickly sculpins, with less sturgeon ingested at higher turbidities.
