  Citation × Citation Citation Abstract Copy Title: MidCoast A - Rapid Bio-assessment 1998 Midcoast Abstract -- Snorkel surveys were conducted in five midcoast watersheds that included the Yachats, Alsea, Yaquina, Siletz, and Salmon Rivers. These surveys were commissioned by the Midcoast Watershed Council, using funds granted by GWEB. The intent of these surveys was to begin to develop a base line for monitoring trends in the distribution and abundance of juvenile Coho, Steelhead and Cutthroat in Midcoast watersheds. Adult Coho escapement for many of these basins has hovered near all time low levels for multiple brood cycles. These surveys intend to identify the core areas within these basins that, at low spawner densities, provide suitable spawning habitats. They also intend to identify areas important for juvenile salmonid rearing such that restoration activities can focus on recovering reaches that adult salmonids are returning to.

The focus of iteration 1.0 was the serpentine portion of the watershed on Forest Service lands. The purpose of the current document and analysis is to expand on this earlier analysis by adding the lower elevation BLM land areas. It identifies the various ecosystem components in the lower elevation areas of the West Fork Illinois River fifth field watershed and their interactions at a landscape scale. The analysis looks at historical ecological components, current ecological components and trends. It makes recommendations for future management actions that could be implemented to reach recommended ecological conditions.

  Citation × Citation Citation Abstract Copy Title: Upper Sprague Watershed Assessment Abstract -- The insight that soil, water and vegetation interact dynamically to produce watershed conditions has led to two principles that have informed the content of this document. First is the importance of basing our restoration and/or our management planning on site-specific conditions, rather than on generalized judgments about conditions at the watershed scale. While watershed-scale statements and analyses are very important for context and for the “big picture,” any actual on-the-ground actions must be rooted in analysis of the actual conditions on the site in question. Second is the importance of focusing on “trend over time,” rather than on static “snapshots” of watershed conditions. The snapshot approach to assessment of conditions compels the analyst or resource manager to make “black or white” determinations about whether or not a given site is acceptable. Focusing on trend over time, on the other hand, allows the resource managers to determine whether fundamental processes are in place that will produce a stable -- but dynamic -- landscape over the long term.

  Citation × Citation Citation Abstract Copy Title: AI - Year 2000 Stream Habitat Conditions in Western Oregon Abstract -- The goals of the habitat monitoring portion of the Oregon Plan program are to develop baseline statistics, describe current conditions and track trends in habitat condition over time. This program functions as the landscape link in the overall Oregon Plan monitoring program. Field work for the habitat monitoring program began in 1998 with coordinated site visitations conducted with the two other Oregon Plan monitoring programs; juvenile rearing survey and adult salmon spawning survey programs. The Oregon Plan Habitat Survey program is nested within the Aquatic Inventories Project (AIP). The AIP was begun by the Oregon Department of Fish and Wildlife (ODFW) in 1990 and has expanded to include a wide variety of inventory, modeling and monitoring efforts. The central purpose of these diverse projects is the inventory of physical aspects of the environment that are important for aquatic life and the habitat needs of salmonids and other fishes during the freshwater stages of their life history. Some of the significant ongoing or recently completed projects that are part of the AIP are: Basinwide cesus surveys, Oregon plan Habitat surveys, Restoration Project Monitoring, Salmonid Habitat and Diversity Watersheds Project, Fish Inventories, Great Basin Redband Trout, Oregon Chub Status and Recovery Project, Salmon River Estuary, and Columbia River Estuary Project.

This revised plan has been developed out of a need to monitor a subset of restoratio n projects from all areas of the Western Oregon Stream Project (Figure 1). This plan encompasses the monitoring period of January 2000 to June 2008, and is a continuation of monitoring activities that were started in the fall of 1995 on the North Coast and continued into the Mid-coast in 1996 and 1997. Much of this plan is a compilation of the original North Coast and Mid-Coast monitoring plans (Hodgson 1996, Thom and Moore 1995). Modifications have been made to better define the monitoring activities, increase efficiency, and strengthen the scientific credibility of the project. Four main questions will be answered as a result of the monitoring activities outlined in this plan. They are: 1)How much stream restoration work has been completed? 2)Is the stream restoration work that is completed leading to improved habitat conditions for salmonids in the treated stream reaches? 3)What fish are utilizing the restored habitats? 4)What are the trends in juvenile abundance in the restored stream reaches?

  Citation × Citation Citation Abstract Copy Title: AI - Oregon Coast Coho Assessment: Habitat Abstract -- In November 2003, the State of Oregon began a comprehensive review of coho and their habitat in NOAA Fisheries’ Oregon Coastal coho Evolutionary Significant Unit (ESU). The purpose of the review is threefold: 1) provide an analysis of the current status and trend in coho populations, their habitat, and related threats; 2) provide NOAA Fisheries with information it requires to determine whether formalized conservation efforts within the ESU justify not listing coho under the Endangered Species Act as outlined in their Policy for Evaluation of Conservation Efforts; and 3) provide information to state agencies, watershed councils, and others participating in the Oregon Plan for and Watersheds (OPSW) so they may assess the success of their OPSW programs and modify them where necessary to better achieve their objectives (i.e. adaptive management). This report describes the current status and trend of instream physical habitat for coho in the ESU as well as summarizes and evaluates instream habitat restoration activities conducted from 1997-2003. Persistence of coho salmon populations in coastal drainages during periods of poor ocean conditions is dependent on the distribution and carrying capacity of freshwater habitat. Coho salmon are sensitive to the quality of habitat during each life stage and seasonal effects on survival are propagated through subsequent life stages (Nickelson et al. 1992). In this chapter, we use measures of habitat quality and quantity to determine overall carrying capacity of freshwater habitat at two juvenile coho life stages: 1) fry through summer parr; and 2) over-winter parr to smolt. From this information we identify life stages at which habitat may limit the coho smolt production capacity for the coho salmon populations considered independent by NOAA Fisheries Technical Recovery Team.

The structure and complexity of the stream habitat influences the species composition, distribution, and production of the fish community. Assessing the status of stream habitat conditions in coastal Oregon streams is important for monitoring the effects of landscape and aquatic management practices on the character of riparian stream habitat. Comprehensive habitat assessments are also important for watershed assessments, restoration planning, and for studying the relationship between stream habitat, fish abundance, and fish distribution. The goals of the Oregon Plan for Salmon and Watersheds (OPSW) Habitat Monitoring Program are to 1) provide an annual update on the status of stream habitat in Western Oregon, and 2) track trends in habitat over time. This report on stream habitat conditions covers sampling that occurred between June and October of 1999. The report is grouped into six different areas: • Current habitat status by Gene Conservation Area (GCA) • The status of habitat in relation to landscape variables • An assessment of the high quality habitat existing on the landscape • A comparison of 1998 and 1999 stream conditions • An analysis of habitat variable precision • An assessment of fish distribution outside of known coho salmon distribution Title: AI - Stream Habitat Conditions in Western Oregon, 1999 Abstract -- The physical habitat of a stream forms the template from which the biological community can develop.

  Citation × Citation Citation Abstract Copy Title: AI - Reference Site Selection and Survey Results 2000 Abstract -- The Oregon Department of Fish and Wildlife (ODFW) Aquatic Inventories Project conducts stream habitat surveys as part of the Oregon Plan for Salmon and Watersheds. The goal of these surveys is to document the status and trends of stream conditions that exist in coastal drainages of western Oregon. To better interpret landscape patterns in aquatic habitat character, the Aquatic Inventories Project has sought to improve the definition of a set of reference conditions from which to compare habitat survey sites. Over the past three years, the set of reference conditions used in analyses was selected from basin-wide habitat surveys conducted between 1992 and 1997. These conditions did not adequately represent the variety of stream sizes, geologic types, or ecoregions present in all coastal streams. The Aquatic Inventories Project selected a set of new reference survey locations that better represent reference conditions in coastal streams for a variety of ecoregions, geologic types, and basins. The reference sites selected for the year 2000 represented watershed areas with low impact from human activities such as roads, development, and forest management. Ideally, areas would have been selected that were completely free from human disturbance, but we concluded it was more important to represent a larger geographic range of conditions across the landscape.

Year: 1977 Progress in an experimental and analytical research program to evaluate and improve the design of downhole heat exchangers (DHEs) for direct applications of geothermal energy is reported. Significant progress has been achieved in characterizing flows in wells and without perforated casings and DHEs installed, determination of energy extraction rates for conventional DHEs in both cased and uncased wells, and utilization of information obtained to develop and substantiate models of heat transfer within the well. Flow characterization was obtained by experimentally measuring temperature and velocity profiles. In uncased wells, there was a relatively large vertical temperature gradient (approximately 0.5{sup 0}C/m) and insignificant measured vertical flow, while for the same wells when cased the temperature gradient was essentially zero (approximately 0.03{sup 0}C/m) and a large vertically upward flow was measured (9 to 14 cm/s as measured with a hot-film anemometer). These show that a significant connection cell is established after installation of the casing. The energy extraction rates for a conventional DHE both before and after casing of a 60 m deep well was experimentally measured. In the uncased well up to 300 kW was obtained while the cased well produced over 500 kW. Analytical heat transfer models were developed for the cased well both with and without DHEs. For the cased well without a DHE, the model predicts flow rates that agree with the measured value within about 30 percent. Further, the energy extraction rates predicted by the models agree even better with the measured values. These models allow the energy extraction rates of design parameter variations to be evaluated. At this stage, only trends can be shown but with additional substantiation they should produce optimum energy extraction designs Title: Evaluation and Design of Downhole Heat Exchangers for Direct Application; Annual Report, May 1, 1976 - July 1, 1977 Author: Culver, G.G.

Such heat production comes from a linear map trend including the Winnsboro, Liberty Hill, Pageland, and Lilesville plutons which parallel the proposed eastern Piedmont Fault system of Hatcher and others (1977). This study, in examining regional versus contact metamorphism and crosscutting relationships between the Winnsboro and Pageland complexes and the major folds and mylonitic zones of this area, provides a relative time framework for the tectonic and plutonic events Title: South Carolina Geothermal Program Final Report; Tectogenesis of the Rocks Surrounding the Winnsboro Intrusive Complex and Reconnaissance and Petrography of the Pageland Pluton Author: Bourland, W.C.

Year: 1979 The Kingman-Williams region, Arizona, possesses few thermal waters of deep origin. Evaluation of 33 waters (8 thermal) reveals that thermal waters are restricted to the Basin and Range tectonic province; no thermal waters were found on the west margin of the Colorado Plateau. The thermal waters appear to rise along north-trending normal faults or flow in deep aquifers in Quaternary sedimentary basins of the Basin and Range province. All thermal waters have distinctive chemistry and discharge at temperatures ranjinj from 28-46°C. They Apparently issue from small isolated jeothermal reservoirs. Geothermometry and chemistry indicate that these are low-temperature reservoirs that probably do not exceed 115°C Title: Wet Geothermal Potential of the Kingman-Williams Region, Arizona Author: Goff, F.E.

Year: 1979 Photolineaments seen on satellite images are usually expressions of deep crustal ruptures. However, photolineaments are omnipresent and an independent expression of regional discontinuities is needed to help rank the photolineaments. Published gravity and magnetic contour maps of Arizona were analyzed to produce a single geophysical lineament map to indicate trends of regional basement structures. This map shows that the southwestern quarter of Arizona is dominated by a NNW-ENE orthogonal system whereas the remainder of the state is gridded by a NW-NE system. North-south systems are present throughout the state, as are EW lineaments. Arizona is transected by the WNW Texas Strand, but other shorter systems trending in the Texas direction are found throughout the state south of the Strand. The major lineament systems as seen on Landsat, gravity, and magnetic maps correlate reasonably Well with known geothermal manifestations. Many other systems are Precambrian, Paleozoic, and/or Mesozoic in age but appear to control the location of Quaternary Volcanic systems Title: Geophysical Lineaments of Arizona Author: Lepley, L.K.

In this, the second and final phase of the work, geological, remote sensing, geochemical, temperature gradient, gravity, aeromagnetic, and electrical resistivity data sets are examined. These data were derived from surveys concentrated on the east and west shores of Upper Klamath Lake. The geological, remote sensing, and potential field data suggest a few northeast-trending discontinuities, which cross the regional north-westerly strike. The near-surface distribution of warm water appears to be related to the intersections of these lineaments and northwest-trending faults. The groundwater geochemical data are reviewed and the various reservoir temperature estimates compared. Particular attention is given to specific electrical conductivities of waters as an interpretational aid to the subsurface resistivity results. A clear trend emerges in the Klamath Falls/Olene Gap area; hotter waters are associated with higher specific conductivities. In the Nuss Lake/Stukel Mountain area the opposite trend prevails, although the relationship is somewhat equivocal; LBL-10140 Title: Geothermal exploration assessment and interpretation, Upper Klamath Lake Area, Klamath Basin, Oregon Author: Stark, M.

Year: 1979 A synthesis and preliminary interpretation of predominantly geophysical information relating to the Klamath Basin geothermal resource is presented. The Swan Lake Valley area, northeast of Klamath Falls, and the Klamath Hills area, south of Klamath Falls, are discussed in detail. Available geophysical data, including gravity, magnetic, electrical resistivity, microearthquake, roving dipole resistivity, audio-magnetotelluric (AMT) and magnetotelluric (MT) data sets, are examined and reinterpreted for these areas. One- and two-dimensional modeling techniques are applied, and general agreement among overlapping data sets is achieved. The MT method appears well suited to this type of exploration, although interpretation is difficult in the complex geology. Roving dipole and AMT are useful in reconnaissance, while gravity and magnetics help in defining structure. For the Swan Lake Valley the data suggest buried electrically conductive zones beneath Meadow Lake Valley and Swan Lake, connected by a conductive layer at 1 kilometer depth. In the Klamath Hills area, the data suggest a conductive zone centered near the northwestern tip of Stukel Mountain, associated with a concealed northeast-trending cross-fault. Another conductive zone appears near some producing hot wells at the southwestern edge of the Klamath Hills. These conductive zones may represent geothermal reservoirs.

Year: 1980 An assessment of the geothermal resources of Caliente, Nevada was made to provide information on resource characteristics and to site 2 (two) 500 ft (152 m) test wells to confirm the resource. The strategy used in the resource assessment employed a logical sequence of work elements that included 1) baseline data collection, 2) field investigations, 3) laboratory analyses and 4) data interpretation and synthesis. Airphoto interpretation indicated that a series of normal faults produced a stepped arrangement in the canyon walls on the west side of Meadow Valley Wash north of downtown Caiente. This area coincides with the area of known geothermal occurrences. Temperature measurements in existing wells indicate a rapid cooling of the geothermal waters as they mix with cold groundwater flows in Meadow Valley Wash. Soil mercury analyses range from 15 ppB to as high as 120 ppB. Trends in soil mercury content may indicate the presence of buried faults. Temperature measured in 2-meter deep auger holes indicated temperatures as high as 40/sup 0/C in an area north of the Lincoln County Medical Facility. Interpretation of chemical analyses, both major and minor, of waters collected from wells and streams in the area failed to conclusively show any mechanisms for the mixing of thermal and nonthermal waters.

Year: 1980 The Colado geothermal area in south-central Pershing County, Nevada is defined by hot water wells in alluvium just west of the West Humboldt Range. Geothermal gradient holes have encountered temperatures up to 113.5/sup 0/C at a depth of 76 m (250 ft) with a gradient reversal in the alluvium below this depth. The West Humboldt Range consists mainly of Triassic to Jurassic slaty shale to quartzite of the Auld Lang Syne Group. Carbonate rocks of the Jurassic Lovelock Formation have been thrust over pelitic rocks on the south end of the area. Erosional remnants of Tertiary tuffs and sediments overlay the metasediments in the West Humboldt Range. The principal structures are high-angle faults striking north-northwest, northeast and north-south. The horst-to-graben transition along the range front consists of several step faults trending irregularly north. The structural pattern in the west edge of the range probably continues to the west under the Quaterary alluvium where the source of the hot water is located. Thermal waters probably rise along a major fault intersection in the Mesozoic rocks then spread out in an aquifer in the alluvium. Several thrust faults are exposed south of Coal Canyon, and a structural break in the Mesozoic rock exists under the canyon. Several low-angle faults are present north of Coal Canyon but their effect, if any, on the geothermal occurrence is not known; DOE/ID/12079-8; ESL-38 Title: Geology of the Colado Geothermal Area, Pershing County, Nevada Author: Sibbett, B.S.
