Bulletin 4279 - Streamlining - An Environmentally Sustainable Drainage Network For The Swan Coastal Plain (Peel-Harvey Catchment), Garry Heady, Neil Guise

Bulletins 4000 -

Community Catchment Centre Pinjarra

A network of over 1400 kilometres of drains and modified natural waterways constructed by the Public Works Department criss-crosses the Peel-Harvey catchment. There are also over 3300 kilometres of minor drains and natural waterways in this same region.

The expansion of agriculture relied on this extensive drainage network, which was designed to ensure rapid drainage of the region. Unfortunately there was little regard to future environmental consequences.

Along with drainage water, these same drains now carry high loads of silt and nutrients. Many of the drains are also degraded and require expensive maintenance annually.

The Prediction Of Sediment And Nutrient Transport In The Buffalo River Watershed Using A Geographic Information System, H. D. Scott, P. A. Smith

Arkansas Water Resources Center Technical Reports

The Buffalo River was established by Congress in 1972 as the first National River in the United States. It is one of the few remaining free-flowing streams in northern Arkansas. The river originates in the higher elevations of the Boston Mountains in Newton County, and generally flows northeastward, intersecting the Springfield and Salem Plateaus as it drops from approximately 2000 feet in the headwaters to around 500 feet at the confluence with the White River in Marion County. It is considered by many to be one of Arkansas' greatest natural treasures, and therefore , there is strong interest in protecting …

Correlating Soil Test Phosphorus Losses In Runoff, D. H. Pote, T. C. Daniel, P. A. Moore Jr., D. J. Nichols, D. R. Edwards, A. N. Sharpley

Arkansas Water Resources Center Technical Reports

Phosphorus in agricultural runoff is often a major cause of accelerated eutrophication of lakes and streams. Previous research has indicated that the amount of dissolved P (DP) in runoff is directly related to P content of the surface soil. Decades of fertilizer application at rates exceeding those of crop uptake have elevated soil test P (STP) levels in areas of intensive crop and livestock production, making this the major source of DP loss in runoff. The objective of our experiment was to relate STP content of Captina silt loam to P concentration and loss in runoff, and determine which STP …

Assessment Of Effectiveness Of Buffer Zones In Removing Impurites In Runoff From Areas Treated With Poultry Litter, I. Chaubey, D. R. Edwards, T. C. Daniels

Arkansas Water Resources Center Technical Reports

Land application of animal manures (e.g. poultry litter, poultry manure, and swine manure) to pasture and range can lead to runoff quality degradation during storms that occur soon after application. Vegetative filter strips (VFS) have been shown to reduce pollution in runoff from row-cropped areas but have not been extensively studied in pasture and range settings. This research involved characterizing performance of fescue VFS in improving quality of runoff from pasture land areas treated with poultry litter and swine manure. The VFS were found to be quite effective in reducing off-site transport of ammonia nitrogen (NH3-N), total Kjeldahl nitrogen (TKN), …

Bulletin 4278 - How To Use Wide Furrow Sowing For Improved Crop Production On Water Repellent Sand, Paul Blackwell, Grant Morrow, Tony Webster

Bulletins 4000 -

Wide furrow sowing is a method for successfully establishing crops of lupins or cereals on non-wetting sands, and improving crop establishment on non-repellent sands. The same principles can be used to assist establishment of fodder shrubs and long-term pasture (e.g. tagasaste and Rhodes grass).

Ground Water Monitoring Project For Arkansas, Phase Iii, Kenneth F. Steele, Steven S. Hill, Terry W. Nichols, H. Don Scott, Paul Vendrell, H. S. Lin

Arkansas Water Resources Center Technical Reports

This report is composed of two parts. The first part is an interpretation of the pesticide and nitrate data collected in Woodruff County based on samples collected during 1994. Because there is an indication that there were hydrological differences between 1994 and 1995, and because most of the pesticide data is from 1994, this interpretive portion is restricted to 1994 data. Six wells initially sampled in 1994 that contained pesticides had continuing contamination in re-sampling in 1994 and 1995. Part II lists a seventh well in Woodruff County that contained pesticides in February and May of 1995

Identification Of Tire Leachate Toxicants And A Risk Assessment Of Water Quality Effects Using Tire Reefs In Canals, S. M. Nelson, G. Mueller, D. C. Hemphill, U.S. Bureau Of Reclamation

Publications (WR)

Cover is an important component of aquatic habitat and fisheries management. Fisheries biologists often try to improve habitats through the addition of natural and artificial material to improve cover diversity and complexity. Habitat-improvement programs range from submerging used Christmas trees to more complex programs using sophisticated artificial habitat modules. Used automobile tires have been employed in the large scale construction of reefs and fish attractors in marine environments and to a lesser extent in freshwater and have been recognized as a durable, inexpensive and long-lasting material which benefits fishery communities.

Recent studies by the U.S. Bureau of Reclamation have quantified …

Information on water research and other water-resource information is disseminated by the Center through public presentations, conferences, and publications. Since 1980, an average of more than 15 principal investigators a …

Determination Of The Efficacy Of Fertilization Practices On Bob Kidd Lake, Richard L. Meyer, Jeanette K. Shipley-Phillips

Arkansas Water Resources Center Technical Reports

Fertilization strategies have been used as a standard practice on Bob Kidd and other lakes and reservoirs to enhance the availability of phytoplankton and zooplankton as food sources for developing fish. The nominal practice is to use a fixed application rate and a constant ratio of nitrogen and phosphorus fertilizer per acre of lake surface. The application technique varies as does the timing. Application techniques vary from spillage and bulk deposition of fertilizer at selected sites to broadcasting of pellets or a pre-mixed slurry via boat and/or airplane. Timing is usually in the spring under appropriate weather conditions.

Nutrient Content Of Runoff Water From Rice Fields, C. E. Wilson Jr., P. A. Moore Jr., R. J. Norman, B. R. Wells

Arkansas Water Resources Center Technical Reports

Current perception is that nutrient runoff from croplands is a significant contributor to poor water quality in some areas. While extensive research has been conducted to survey and ameliorate this problem for several upland crops, little work has been done to evaluate the problem with flooded rice (Oryza sativa, L.) soils. Since rice production utilizes a major portion of the total irrigation water usage for certain areas, it is important to understand the contribution of rice production to non-point source N and P in surface water. Several production fields were selected to evaluate the concentrations of nutrients in the floodwater …

The Influence Of Reservoir Basin Morphometry On Phytoplankton Community Structure, Richard L. Meyer, G. Keith Trost

Arkansas Water Resources Center Technical Reports

The research protocol was designed to compare three reservoirs with similar physical environments but different morphometry. Three reservoirs on the western edge of the Ozark uplift were selected because of their similar substrate and climatic condition. The reservoirs primarily differed in morphometry. Two of the reservoirs were of identical size, Bob Kidd and Prairie Groves Lakes, but of different configuration, semicircular and linear, respectively. The bifurcated lake, Lincoln Lake, was of smaller size. Each lake is dimictic. Each of the lakes were nitrate-N limited while soluble reactive phosphorus-P is available and not restricting the growth of phytoplankton. Although the pattern …

Completion Report: Pesticide And Nitrate Monitoring Results For Craighead, Mississippi, And Poinsett Counties, Arkansas: Phase Ii, Kenneth F. Steele, William R. Clayton, Terry W. Nichols, Paul F. Vendrell

Arkansas Water Resources Center Technical Reports

Because of the concern for potential contamination of ground water by agricultural chemicals, 38 wells drilled in the Mississippi River Valley alluvial aquifer in Mississippi County and the eastern parts of Craighead and Poinsett Counties, Arkansas were analyzed for pesticides and nitrate. The pesticide, fluometuron, was detected in one sample at a concentration of 0.5 mg/L. Bentazon was detected in three samples at concentrations of 2.5, 0.3, and 0.3 mg/L. The occurrences of the pesticides appear to represent isolated incidents rather than a widespread aquifer contamination. All detections were below health and safety standards. Nitrate is present in several wells …

Effect Of Drying On Cyromazine Loss From Surface-Applied Caged-Layer Manure, T. C. Daniel, D. H. Pote, D. R. Edwards

Arkansas Water Resources Center Technical Reports

In Arkansas, much of the environmental concern related to water quality has focused on the high volume of poultry fecal waste spread on the surf ace of local pastures to fertilize forage grass. Cyromazine (N-cyclopropyl-1,3,5-triazine-2,4,6- triamine), a feed-through larvicide used to control house flies (Musca domestica), is often a component of caged-layer manure. Cyromazine is quite soluble and stable in water, and previous research has shown that it can be readily washed from pasture plots by intense rainfall. Therefore, a study was conducted to evaluate increased drying time as a best management practice technique for reducing cyromazine runoff losses from …

Computer Simulation Model Calibration And Validation For Prediction Of Water Quality Impacts Of Poultry Waste Disposal, D. R. Edwards, T. C. Daniel

Arkansas Water Resources Center Technical Reports

Runoff and water quality data collected from two pairs of grazed fields in northwestern Arkansas were analyzed to support efforts to model runoff quality from areas receiving poultry manure and other fertilizer sources. The monitoring period described in this report was September 1, 1991 to April 30, 1993. One of each pair of fields was fertilized with inorganic fertilizer, and the other received either poultry litter or manure. Losses of fertilizer constituents were quite low from an agronomic standpoint, ranging from approximately 2-11 kg N/ha/year and 0.5-4.1 kg P04-P/ha/year. Annual losses of fertilizer constituents were dominated by only a small …

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 …

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 …

Besides being extremely vulnerable to contamination, the springs often discharge and insufficient volume of water needed for public consumption and dilution of the City’s treated wastewater. Thus the City wishes to find an additional source of water and views nearby Shakertown Spring as a possibility. The study has three main objectives: 1) delineation of the Auburn, Summers, and Shakertown Springs ground water basins, 2) determination of the volume of available water at …

Arkansas Agricultural Chemical Ground-Water Management Plan, Gerald King, Darryl Little, Tim Jessup, Charles Armstrong

Arkansas Water Resources Center Technical Reports

The Arkansas Agricultural Chemical Ground-Water Management Plan (SMP) is based on the Draft State Pesticide Ground- Water Management Plan Guidance and The Pesticides and Ground-Water Protection Strategy prepared by the U.S. Environmental Protection Agency (EPA). The need for a plan to protect ground water from contamination by agricultural chemicals and agents arises from evidence nationwide that using these chemicals can, in some instances, lead to contamination. In February 1988, EPA proposed a strategy to regulate certain pesticides by prohibiting their use in areas vulnerable to leaching unless a state develops and implements an acceptable management plan. The advantage of a …

Relationship Between Ground And Surface Water Quality In Karst Systems, Richard L. Meyer

Arkansas Water Resources Center Technical Reports

Springs in Northwest Arkansas may originate from relatively small fractures in rock strata or from cave systems. The water emerging from these springs is frequently used as water sources for plants, animals and humans. The quality of the ground water source and the emerging water are uncertain and frequently unknown. In addition, the opportunity to monitor changes in water quality during flow from origin (water entering the cave) to emergence is uncommon. Cave systems with definable drainage basins and accessible sampling points near the midpoint of the cave are also uncommon. Examining the interface between the quality of surface water …
