Fisheries Research Contract Reports

Report to the Water Corporation of Western Australia

This report describes the fishes and freshwater crayfishes of the Donnelly and Warren River catchments and provides a risk assessment to these fauna of the proposed extraction of water from Record Brook (tributary of the Donnelly River) and subsequent transfer to Scabby Gully Dam (Warren River catchment). The proposed location of the structure in Record Brook is at the gauging station ~1 km upstream from the confluence with the Donnelly River. The project aims to divert peak flows in the winter and spring flow period, transferring around 500 ML each year. The …

Nutrient And Fecal Microbe Sources For A Eutrophic Lake And Recommended Remediation Steps, Wilgreen Lake, Madison County, Kentucky, Walter S. Borowski, Theresa A. Aguiar, Jill Hunter, Erin C. Jolly, Richard D. Stockwell

EKU Faculty and Staff Scholarship

Wilgreen Lake is a man-made lake, classified as nutrient-impaired (303d list) by the EPA and State of Kentucky. The lake drains a watershed with residential developments, cattle pasture, modified woodlands, and some industrial/urban usage in the city of Richmond. The principal tributaries are Taylor Fork and Old Town Branch that meet to form the trunk of the lake approximately one mile in length. The upper reaches of Taylor Fork are adjacent to a densely-packed (quarter-acre lots) housing development with septic systems, and its watershed drains some portions of southern Richmond. Old Town Branch drains cattle pasture and residential areas of …

The Functions And Values Of Fringing Salt Marshes In Northern New England, Usa, Pamela A. Morgan, David M. Burdick, Frederick T. Short

Environmental Studies Faculty Publications

Although large salt marshes of the northeastern United States have been studied extensively, very little is known about the smaller, fringing marshes in this area, despite the fact that they are a common habitat type. We compared the functions and values of five fringing salt marshes (FM) to those of five meadow marshes (MM) along the southern Maine/New Hampshire coast. Specifically we compared their primary production, soil organic matter content, plant diversity, sediment trapping ability and wave dampening properties. Also explored were the relationships between these functions and several physical characteristics at each site, including soil salinity, percent surface slope, …

Fisheries Research Report No. 188 - Results Of The 2007 Survey Of The Albany Marine Area For Introduced Marine Species, Justin I. Mcdonald, Fred E. Wells, Michael J. Travers

Fisheries Research Reports

A survey of the Albany marine area (King George Sound, Princess Royal Harbour and Oyster Harbour) for introduced marine pest species was conducted in 2007. This survey was trialling the new system of monitoring for introduced marine pests developed by the National Introduced Marine Pests Coordination Group (NIMPCG). This study represents one of the first trials of this system (the first trial commenced in South Australia is still ongoing). In this survey fifty-two of the fifty-five potential pest species were targeted. Three species were excluded on the basis of salinity and/or temperature tolerances being exceeded. A wide variety of sampling …

Monitoring Water Quality On Tributary Inflows To Lake Mead And On A Transect Of The Overton Arm, Jorge Arufe, Robert Burrows

Lake Mead Science Symposium

The USGS, in cooperation with the NPS and BOR (Bureau of Reclamation), is collecting water quality data to determine the temporal changes and spatial distributions of natural and anthropogenic compounds entering the Overton Arm of Lake Mead. These efforts and others already underway on the lake by BOR, USGS, and SNWA will aid in the development of a reservoir model of the lake. The effects of the flood flows on the water quality of the Overton Arm are largely unknown and necessary for model development and verification.

Water quality physical parameters are continuously monitored near the mouth of the Virgin …

History Of Contaminant Inputs Into Lake Mead Derived From Sediment Cores, Michael R. Rosen, Peter C. Van Metre, David Alvarez, Kathy R. Echols, Steven L. Goodbred

Lake Mead Science Symposium

Assessing the changes in contaminant inputs (both organic and inorganic) over time is important in determining sources and sinks of these inputs. Variations in contaminant input were assessed in four sediment cores taken in 1998 from three different parts of Lake Mead (two from Las Vegas Bay and one from Overton Arm and Virgin Basin). Sediments were analyzed for major and trace elements, radionuclides, and organic compounds. Anthropogenic contaminant concentrations are greatest in Las Vegas Bay reflecting inputs from the Las Vegas urban area, although concentrations are low compared to sediment quality guidelines and to other USA lakes. One exception …

Surface Water Monitoring For Fecal Indicator Bacteria In High-Use Sites Of The Lake Mead National Recreation Area, Patricia Cruz, Vanessa Stevens, Jessie Rinella

Lake Mead Science Symposium

The Lake Mead National Recreation Area incorporates 1.5 million acres, including Lake Mead and Lake Mohave. The abundance of recreational activities on Lakes Mead and Mohave can impact the contaminant levels in the water, potentially affecting the health of individuals in contact with the water. The purpose of this study was to review and synthesize information obtained for projects conducted by partner agencies from the Water 2025 Conservation Initiatives, specifically bacterial concentration in high-use areas. Surface water samples were collected between May and September, at 9 high-use sites from 2003 to 2007. Culture analysis was performed to determine the concentration …

Assessment Of Endocrine And Gonadal Condition Of Male Largemouth Bass From Lake Mead, Nevada, Reynaldo Patino, Steven L. Goodbred, Erik Orsak, Jill A. Jenkins, Michael R. Rosen

Lake Mead Science Symposium

Las Vegas Bay (LVB) of Lake Mead receives combined flows of tertiary treated wastewater effluent, urban runoff, and groundwater from the Las Vegas metropolitan area. This study examined the potential for endocrine disrupting effects of these anthropogenic inputs on male largemouth bass (Micropterus salmoides). Adult male bass were collected at two sites within Lake Mead: Overton Arm (OA, reference site), and Las Vegas Bay (LVB). Post-spawn fish were collected in July 2007 (n = 6-10 per site) and pre-spawn fish in March 2008 (n = 13 per site). Post-spawn fish were characterized by regressed testes whereas pre-spawn bass had full-grown …

A Century Of Climate Change For Fairbanks, Alaska, Gerd Wendler, Martha Shulski

School of Natural Resources: Faculty Publications

Climatological observations are available for Fairbanks, Interior Alaska, for up to 100 years. This is a unique data set for Alaska, insofar as it is of relatively high quality and without major breaks. Applying the best linear fit, we conclude that the mean annual temperature rose from -3.6°C to -2.2°C over the century, an increase of 1.4°C (compared to 0.8°C worldwide). This comparison clearly demonstrates the well-known amplification or temperature change for the polar regions. The observed temperature increase is neither uniform over the time period nor uniform throughout the course of a year. The winter, spring, and summer seasons …

Demonstrating Sustainable Farm Management Systems. Final Report For Rcg05-Ord13, Tara Slaven, Francis Bright, Jodie Hawley, Joe Sherrard

Natural resources research reports

The Ord River Irrigation Area (ORIA) has a 'flow through' irrigation system. That is, irrigation water is diverted from Lake Kununurra and any waste water from the irrigation system and farms flows directly back into the river downstream. This means that any sediment, nutrient or chemicals in tailwater from farms flows straight into the river.

The Ord Land and Water Management Plan 2000 specifies goals to improve surface water quality. The goals are to reduce the load of chemical and nutrient contamination and sediment in tailwater by 40 per cent.

The aim of this project was to develop and demonstrate …

A System For Estimating Bowen Ratio And Evaporation From Waste Lagoons, Arturo I. Quintanar, Rezaul Mahmood, John H. Loughrin, Nanh Lovanh, Monica V. Motley

High Plains Regional Climate Center: Staff Publications

A low‐cost system was deployed above a swine waste lagoon to obtain estimates of Bowen ratios and characterize lagoon temperatures. The system consisted of humidity and temperature sensors and anemometers deployed above the lagoon, water temperature sensors, and a meteorological station located by the lagoon. To evaluate the system, data was analyzed from the 25th through 28th June 2007. Bowen ratios showed diurnal behavior near the lagoon surface characterized by negative values during day and positive ones at night. Latent (evaporation) and sensible heat fluxes were towards the atmosphere and the lagoon, respectively for most of the day. A diurnal …
