Land Use Patterns In Relation To Lake Water Quality In The Salmon Lake Watershed, Problems In Environmental Science Course (Biology 493), Colby College, Colby College

Colby College Watershed Study: Salmon Lake and McGrath Pond (2009, 1993)

Salmon Lake has a history of algal blooms which have decreased the recreational and aesthetic value of the lake (Nichols et al. 1984). As early as the 1920’s, Salmon Lake was reported to have poor water quality. Algal blooms were reported throughout the 1970’s. Numerous complaints led to a study in 1975 by the Maine Department of Environmental Protection (MDEP) and another in 1984 by the U.S. Geological Survey to determine the cause of the accelerated algal growth in the ponds. Both studies concluded that the primary cause of these algal blooms was high concentrations of phosphorus in the water. …

Effects Of Domestic Wastewater Effluent On The Water Quality And Aquatic Macroinvertebrates In A Sharp County, Arkansas Stream, Linda E. Moss, George L. Harp

Journal of the Arkansas Academy of Science

The purpose of this study was to determine whether the effluent of the Ash Flat Wastewater Treatment Plant changes the water quality or aquatic macroinvertebrate community structure of North Big Creek. Weekly water samples were analyzed for pH, N, P, COD, TSS and fecal coliform bacteria from 17 June to 19 August 1992. Aquatic macroinvertebrates were collected biweekly using a Turtox Indestructible™ Dip Net, and density indices were calculated. Station 1, above the effluent, was a spring habitat. Fecal coliform, N, P, TSS and COD values were higher at this station, while the aquatic macroinvertebrate community was relatively simple. The …

A Review Of Four On-Farm Water Supply Demonstration Farms, M H M Casey, I A F Laing

Resource management technical reports

In March 1982, the Western Australian Government allocated $100,000 to the Department of Agriculture to demonstrate appropriate, reliable, on-farm conservation technology on four farms in the north-eastern wheatbelt. The Government grant was matched dollar for dollar with the farmers funds with a maximum of $25,000 grant to any one farm. The demonstrations used existing techniques, such as dams and roaded catchments, to establish permanent drought-proof water supplies.

Completion Report: Arkansas State Pesticides In Ground Water Monitoring Project, Terry Nichols, Paul Vendrell, Kenneth Steele

Arkansas Water Resources Center Technical Reports

Executive Summary. The Arkansas State Plant Board (ASPB) has completed a monitoring project in Ashley County, Arkansas. Twenty-nine samples from 23 wells were analyzed for 10 pesticides commonly used in Ashley County. The only detection was Metolachlor, at 0. 71 ug/L, in one well. When the well was subsequently resampled no pesticides were detected. Fifteen of the wells were also tested for nitrate. In one of the wells nitrate was measured at 10.3 mg/L. The other wells were all below 0.05 mg/L. Extensive quality assurance (QA) data collected during the project indicate that 94% of the pesticide data meet all …

Woodruff County Groundwater Vulnerability, H. D. Scott

Arkansas Water Resources Center Technical Reports

There is much unknown about the extent of pesticide contamination of groundwater in Arkansas. In recent years, several research studies have been conducted where wells for irrigation and domestic uses have been sampled and analyzed for pesticides (Lavy, 1988; USGS,1993; Nichols, et al., 1993). For state and federal regulatory agencies, evaluation of the potential ground water contamination begins with considering those areas in Arkansas where pesticides are used and where the ground water is vulnerable to contamination. With a relatively large area of crops grown in Arkansas and only limited financial resources available for chemical analyses by state and federal …

G93-1191 Glossary Of Water-Related Terms, William L. Kranz, Delynn Hay, James W. Goeke, David Gosselin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide is a glossary of water quantity, quality and human health related terms involving water. Terms are defined in contexts that could affect Nebraskans. We depend upon water for our very existence. The impact of water quality and quantity issues has never been greater. Yet the terminology used to describe the water we drink, the water we provide to plants and animals, the water stored underground, in lakes, rivers, and oceans, is not well understood by many Nebraskans. This listing of water-related terms is intended to reduce the potential for misunderstanding presentations made by elected officials, environmental agencies and …

The Potential Effects Of Climate Change On Summer Season Dairy Cattle Milk Production And Reproduction, Peggy L. Klinedinst, Donald A. Wilhite, G. Leroy Hahn, Kenneth G. Hubbard

National Drought Mitigation Center: Faculty Publications

The potential direct effects of possible global warming on summer season dairy production and re-production were evaluated for the United States and Europe. Algorithms used for milk production and conception rate were previously developed and validated. Three widely known global circulation models (GISS, GFDL, and UKMO) were used to represent possible scenarios of future climate. Milk production and conception rate declines were highest under the UKMO model scenario and lowest under the GISS model scenario. Predicted declines for the GCM scenarios are generally higher than either “l year in 10” probability-based declines or declines based on the abnormally hot summer …

Effects Of Moonlight And Daylight On Hydroacoustic Estimates Of Pelagic Fish Abundance, Chris Luecke, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

To determine how moonlight and daylight affect hydroacoustic estimates of fish abundance, we used a dual-beam transducer and echo integration to survey pelagic fish (primarily Bonneville ciscoes Prosopium gemmifer) in Bear Lake, Utah and Idaho. During the new moon, the fish were dispersed (not schooling) below the thermocline, chiefly at the depths of 10–20 m. At full moon, they were dispersed but much closer to the bottom, where they were difficult to detect. Acoustic estimates offish density and biomass during full moons were approximately 50% of values derived during new moons. A diel survey during a new moon indicated that …

Ichthyofauna Of The Village Creek System, Anthony Holt, George L. Harp

Journal of the Arkansas Academy of Science

Village creek is a lowland stream lying in the Mississippi Embayment in Randolph, Lawrence and Jackson counties in northeastern Arkansas. The stream has been channelized in Randolph and Lawrence counties as have most of its tributaries. The Jackson County portion of the stream has not been channelized. Twelve sites were sampled seasonally by seining along Village Creek and its tributaries. In addition to seasonal work, six sites were sampled from one to three times each by several methods. A total of 8000 specimens was collected by all means used (7754 at seasonal sites and 246 at supplemental sites). Forty-two species …

An Empirical Model Of Gastric Evacuation Rates For Fish And An Analysis Of Digestion In Piscivorous Brown Trout, E. He, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

The gastric evacuation rates of brown trout Salmo trutta (0.9–1.6 kg) feeding on fingerling rainbow trout Oncorhynchus mykiss (3.5–7.6 g) were measured in the laboratory at five temperatures (4.5, 9.0, 14.0, 19.0, and 22.5°C). Instantaneous gut evacuation rates (Re) increased exponentially with temperature (T): Re = 0.053se^0.073T, r^2 = 0.98; they varyied from 7%sh^–1 at 4.5°C to 29%sh^–1 at 22.5°C. Linear regressions described the relationship between time and qualitative measures of fish digestion, thus allowing investigators to determine how long an ingested fish would be identifiable at different temperatures. An analysis of published evacuation rates (N = 121) of 22 …

Water Quality Impacts Of Natural Riparian Grasses Part 1: Empirical Studies, B. J. Barfield, R. L. Blevins, Alex W. Fogle, C. E. Madison, S. P. Inamdar, D. I. Carey, V. P. Evangelou

KWRRI Research Reports

Studies were conducted on the effectiveness of natural riparian grass buffer strips in removing sediment and ag chemicals from surface runoff. No till and conventional tillage erosion plots served as the sediment and chemical source area. Runoff from the plots was directed onto 15, 30, and 45 foot filter strips where the inflow and outflow concentrations and sediment size distributions. Trapping percentages for sediment and ag chemicals typically ranged near or above 90%. An evaluation was made of the distribution of trapped chemicals among infiltrated mass and mass stored in the surface layer and on plant surfaces. The analysis showed …

Water Quality Impacts Of Naturals Riparian Grasses Part 2: Modeling Effects Of Channelization On Sediment Trapping, S. P. Inamdar, B. J. Barfield, D. I. Carey, Alex W. Fogle

KWRRI Research Reports

A methodology is developed to determine expected sediment trapping in riparian vegetative filter strips considering channelization of flow. The framework consists of defining the channel network stochastically, with deposition/detachment in each channel being modeled deterministically. The two approaches were then combined to develop a model which could predict expected trapping efficiencies for vegetative filters under known field conditions. The model was then extended to include conditions such as rainfall on the filter so as to make it applicable to generic field situations.

Field and laboratory studies were conducted to collect and estimate data to develop and evaluate the model. sediment …

A Preliminary Study Using The Willow Cutting Method To Reduce Lake Shoreline Erosion, Jeffrey L. Bushur

Masters Theses

The Charleston Side-Channel Reservoir has been experiencing extensive shoreline erosion since its completion in 1982. A diagnostic/feasibility study of the reservoir in 1992 rated shoreline erosion as the second largest source of sedimentation. Sedimentation reduces the reservoir volume, increases nutrient loading, and increases water turbidity.

As a part of Clean Lakes Program Phase II, the use of willow cuttings for bank stabilization was proposed as a possible treatment for shoreline erosion. While the use of willows for streambank stabilization has been extensively reported, lake documentation is rare. This experiment determined the feasibility of such action for the Charleston Side-Channel Reservoir …

Albany Harbours Sampling Program - Experiences, Myths And The Need For Standards, David Weaver

Conference papers and presentations

Making accurate and precise estimations of pollutant loadings is becoming more important as our waterways suffer from increased inputs of pollutants and as statutory requirements to meet target loads are established. The most studied pollutant in waterways in WA is phosphorus (P) since it is reported to be the stimulus for algal growth. Many reports publish nutrient load data without any discussion of potential errors in sampling, chemical analysis or load calculations, or any discussion of the assumptions made and conclusions drawn from those calculations. The result can be the adoption of incorrect sampling, analytical and calculation procedures, leading ultimately …

Lake Level Changes Within The Yellagonga Regional Park: A Historic Perspective, Jennifer A. Hamann

Theses : Honours

The Yellagonga Regional Park is located approximately 20 km north of Perth and 6km east of the coast, in the City of Wanneroo. The park is comprised of Lake Joondalup, Beenyup Swamp, Wallubuenup Swamp and Lake Goollelal, a largely directly-linked wetland system and their surrounds. The importance of wetlands within the Perth Metropolitan area is widely documented with only 20% of the pre-European settlement wetlands remaining. (Godfrey, 1988; Davis, 1988) By comparison wetlands in the Yellagonga Regional Park are relatively natural in their state. (LeProvost, 1987) The park is of significance due to its conservation value, providing a varied array …

Larval Chironomids Of The St. Francis Sunken Lands In Northeast Arkansas, Betty G. Cochran, Edmond J. Bacon Jr., George L. Harp

Journal of the Arkansas Academy of Science

Sixty semi-annual collections (August 1987-July 1988) were made from 30 stations by sampling each station twice for 1.5 man-hours with an aquatic dipnet. Larval chironomids were mounted on slides and identified at 400-1000 magnifications using a Leitz Dialux 20 EB microscope. A survey of the aquatic macroinvertebrates of the St. Francis Sunken Lands in northeast Arkansas revealed 36 taxa of Order Diptera, Family Chironomidae. The taxa were used to evaluate the general health of the aquatic environment. Stations that were located within the least disturbed areas, which were old river channels and oxbows, contained the highest number of organisms and …

Environmental Analysis Of The Caddo River And Its Tributaries: Comparison Of Water Quality During 1992 With 1974-75, Kelly L. House, Jimmy D. Bragg, Clark Kuyper, T. Kent Thomas, C. Renn Tumlison

Journal of the Arkansas Academy of Science

Environmental data related to water quality of the Caddo River and its tributaries were collected from March - October, 1992, and compared with data from August, 1974 - May, 1975. Bacterial, chemical and physical parameters were investigated at six river locations and thirteen tributary sites. Ammonia, nitrates, soluble phosphorus, turbidity and fecal coliform were significantly lower, and sodium and potassium were significantly higher in 1992 than during the previous study. Bacterial loading exceeded EPA criteria at some locations during both studies.

Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George

Bulletins 4000 -

Careful planning can mean the difference between the success or failure of a tree planting program . Healthy , well-e stablished trees stand a better chance of survival, grow faster and are more resistant to insect attack. The need for time-consuming watering in summer is also eliminated.

The high rainfall coastal plain extends from Perth to Busselton and inland to the Darling Scarp. It receives about 800 to 1000 mm annual rainfall.

Site preparation is ideally started in summer. For a winter planting, decide before March where to plant, which varieties and how many trees to plant. Early planning allows …
