Buntine-West Wubin And West Maya Catchment Management Report, William Oldfield, Natalie Hunt
Natural resources published reports
Buntine West/Wubin land Conservation District was formed when a number of landholders wanted to extend and join on to some existing deep drains. At first the group concentrated on the deep drains with some farmers joining on anda project to connect the drains up througha naturally occurring saline area and to run the main drain into a salt lake system. Funding was attained for 50% of the project and farmers with drains paid for the rest. It was considered unfair for landowners whose land this drain went through to pay all the cost as it was not draining arable land. …

Water Resources Studies Along The Arkansas-Oklahoma Border, Kenneth F. Steele
Arkansas Water Resources Center Technical Reports
The watershed approach to water resource issues recently has been re-discovered. Scientists and managers recognize the need to consider the entire watershed when delineating and solving today's water resource problems. A simple example is the effect that streams have on the ultimate "health" of a reservoir. Although technically the term watershed should be used only in reference to surface water, the importance of ground water is included in the watershed approach to problems. In recognition that we all "live upstream and downstream," the Arkansas Water Resources Center and the Oklahoma Water Resources Institute sponsored a conference titled "Water Resource Studies …

Land Use Patterns In Relation To Lake Water Quality In The Long Pond, South Basin Watershed, Problems In Environmental Science Course (Biology 493), Colby College, Colby College
Colby College Watershed Study: Long Pond, South (2007, 1995)
Long Pond, South Basin receives nutrient inputs from a variety of sources, including roads, construction projects, logging practices, and human waste from subsurface waste disposal systems. If any of these sources are near tributaries or the shoreline, the nutrients can be easily transported into the lake itself. The lake is also used recreationally for boating, fishing and swimming, and is utilized as a source of drinking water for seasonal shoreline residences. The watershed contains the Mt. Vernon and Belgrade transfer stations, and the dump has been capped at each of these stations.
Historically, Long Pond, South Basin has not suffered …
Chemical And Biological Monitoring Of A Constructed Wetland On Jones Branch Treating Acid Mine Drainage, Barbara A. Ramey, George Chalfant, Jon A. Walker
Chemical And Biological Monitoring Of A Constructed Wetland On Jones Branch Treating Acid Mine Drainage, Barbara A. Ramey, George Chalfant, Jon A. Walker
KWRRI Research Reports
Acid mine drainage (AMD) from an abandoned underground coal mine in the Jones Branch watershed in McCreary County, KY, substantially reduced water quality in Jones Branch. Downstream from the mine seeps, the pH was routinely below 4.5 and concentrations of most heavy metals, especially iron, were elevated. A cattail wetland (1,022 m2) was constructed on Jones Branch in 1988-1989 to obviate the effects of the AMD. Monthly chemical monitoring was performed on the water from above, from below, from the inlet and outlet of the wetland, and from the 25 cells within the wetland. Based on chemical monitoring, …

Relating United States Crop Land Use To Natural Resources And Climate Change, K. G. Hubbard, F. J. Flores-Mendoza
National Drought Mitigation Center: Faculty Publications
Crop production depends not only on the yield but also on the area harvested. The yield response to climate change has been widely examined, but the sensitivity of crop land use to hypothetical climate change has not been examined directly. Crop land-use regression models for estimating crop area indices (CAIs) - the percent of land used for corn, soybean, wheat, and sorghum production - are presented. Inputs to the models include available water-holding capacity of the soil, percent of land available for rain-fed agricultural production, annual precipitation, and annual temperature. The total variance of CAI explained by the models ranged …

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.

Land Use Patterns In Relation To Lake Water Quality In The Long Pond, North Basin Watershed, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College
Colby College Watershed Study: Long Pond, North (2006, 1994)
Long Pond has been used recreationally over time for boating, fishing and swimming. Additional uses include drinking water and various types of waste disposal. In past winters, sawdust from lumber mills has been placed on the ice that covers the north basin of Long Pond (Ed Mayer pers. comm.). This may raise total phosphorus levels at depth and could lead to problems in the future. Activities which raise organic sediments input into the lake should be avoided.
A major purpose of our study was to analyze the present water quality of Long Pond, North Basin, including the biotic and abiotic …

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 …

With the discovery of the role of trace elements, large tracts of land in the south west of Western Australia, previously regarded as unsuitable for agriculture, were cleared in the 1950s and 1960s. Much of this land was taken up as Conditional Purchase Blocks, a scheme which enabled conversion of unalienated crown land to freehold title providing a set proportion of the block was 'developed'.
However, the removal of the natural deep rooted vegetation and its replacement with pasture species (up to 90% of privately owned land in the Napier-King LCD area is cleared) has not been without problems. The …

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. …

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 …

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 …

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 …

Effects Of Waterlogging On Crop And Pasture Production In The Upper Great Southern, Western Australia, J F. Wallace, G A. Wheaton, D J. Mcfarlane
Effects Of Waterlogging On Crop And Pasture Production In The Upper Great Southern, Western Australia, J F. Wallace, G A. Wheaton, D J. Mcfarlane
Technical Bulletins
Separate estimates of the effect of waterlogging on cereal yields were made using rainfall and crop yield statistics, and remote sensing. Both methods showed that waterlogging costs tens of millions of dollars each year in lost crop production in the Upper Great Southern Statistical Division. The costs will be over $100 m in wet years. Losses in pasture production are likely to be of a similar magnitude, but are harder to quantify.

Red Kangaroos Can Set Back Range Regeneration, Andrew Mclaughlin
Journal of the Department of Agriculture, Western Australia, Series 4
After years of severe drought, stocking rates in Western Australia s arid rangelands have been kept low since the 1970s to allow native pastures to regenerate. As well, extensive re-seeding programs have started and sheep and cattle grazing on these areas has been restricted or eliminated. However, pasture regeneration in the rangelands can only succeed when grazing by all animals - sheep, cattle, kangaroos, goo.ts, camels, brumbies and donkeys - is controlled Many more red kangaroos roam throughout Western Australia's pastoral areas today than 20 years ago. The installation of windmills and troughs to water domestic livestock has allowed kangaroo …

A Study Of The Summer Steelhead, Oncorhynchus Mykiss In Several Intermittent Tributaries Of The Satus Creek Basin, Washington, Joel Denney Hubble
All Master's Theses
The summer steelhead, Oncorhynchus mykiss population was studied in three intermittent tributaries in the Satus Creek Basin. There was a strong tendency for post emergent fry, resulting from redds located in intermittent reaches to move downstream. However, survival to perennial flow conditions was very low. Steelhead production in Dry Creek appears to be lower than in Logy Creek, because of elevated water temperatures and minimal spring and summer stream flow.
