CD-ROM of this document plus images obtained to date - 1 - - 2 - 1.0 INTRODUCTION The Fish River Water Supply Scheme [FRWS] is a medium size but important water supply with the headwaters in the Central Highlands of NSW, west of the Great Dividing Range and to the south of Oberon. It supplies water in an area from Oberon, north to Portland, Mount Piper Power Station and beyond, and east, across the Great Dividing Range, to Wallerawang town, Wallerawang Power Station, Lithgow and the Upper Blue Mountains. It is the source of water for many small to medium communities, including Rydal, Lidsdale, Cullen Bullen, Glen Davis and Marrangaroo, as well as many rural properties through which its pipelines pass. It was established by Act of Parliament in 1945 as a Trading Undertaking of the NSW State Government. The FRWS had its origins as a result of the chronic water supply problems of the towns of Lithgow, Wallerawang, Portland and Oberon from as early as 1937, which were exacerbated by the 1940-43 drought.

  • Menindee Lakes, the Lower Darling River and Darling Anabranch)
    THE LIVING MURRAY Information Paper No. 10 IPTLM0010 Health of the River Murray Menindee Lakes, the Lower Darling River and Darling Anabranch) Contents Environmental assets within the river zone Current condition of environmental assets Reasons why some environmental assets have declined in value What can be done to restore environmental values? Existing environmental flows initiatives The system-wide perspective References Introductory Note Please note: The contents of this publication do not purport to represent the position of the Murray-Darling Basin Commission. The intention of this paper is to inform discussion for the improvement of the management of the Basin’s natural resources. 2 Environmental assets within the river zone The lower Darling River system is located at the downstream end of the River Murray system in NSW and is marked by Wentworth to the south and Menindee to the north. It encompasses the Menindee Lakes system, the Darling River below Menindee and the Great Anabranch of the Darling River (referred to hereafter as the Darling Anabranch) and associated lakes. These are iconic riverine and lake systems within the Murray-Darling Basin. In addition, a vital tributary and operating system feeds the lower River Murray. The climate of the area is semi-arid with an annual average rainfall of 200 mm at Menindee (Auld and Denham 2001) and a high potential annual evaporation of 2,335 mm (Westbrooke et al. 2001). It is hot in summer (5–46oC) and mild to cold in winter (-5–26oC). In particular, the lower Darling River system is characterised by clusters of large floodplain lakes, 103 to 15,900 ha in size, located at Menindee and along the Darling Anabranch.

  • Species Summaries Catfish
    Species Summaries Catfish 23 Analysis and Summary of Historical Information on Native Fish During the course of this project a large amount of historical information was collected on the native fish of the Murray-Darling Basin. Most of this has been reviewed on a catchment by catchment basis in the previous sections. The primary aim of the project was to collect historical information and identify the original distribution and habitat preferences of Trout cod and, secondarily, the other large native fish species within the southern half of the Basin. This section provides an analysis and summary of all the information collected. The summary is presented on an individual species basis and for each the information is discussed under the following headings: 1. European Discovery: A description of the earliest European encounters with each species; 2. Aboriginal Names: A collation of names reported for each species in the writings of early Europeans attributed to aboriginal people. The list is certain to be very limited in scope as until comparatively recently few publications documented aboriginal language; 3. European Names: Briefly outlined is a history of the changes and synonyms of the scientific names used for each species, followed by the common names in general use from the past up to the present. In an earlier section a lengthy review was presented, covering the history of the taxonomic argument over Trout cod that continued for nearly 150 years. While previously discussed, a brief summary of the key changes in the scientific name of the Trout cod along with the basic reasons for these changes, has been provided; 4.

  • Cape Fear River Basin Action Plan for Migratory Fish
    Cape Fear River Basin Action Plan for Migratory Fish e Fe ap ar C R p i i v e h r s developed by P r a r t n e April 2013 The Cape Fear River Partnership The Cape Fear River Partnership was formed in 2011 with a vision of a healthy Cape Fear River for fish and people. The partnership's mission is to restore and demonstrate the value of robust, productive, and self-sustaining stocks of migratory fish in the Cape Fear River. Building on the momentum of the newly constructed fish passage at Lock & Dam #1, this partnership of key federal, state, local, academic, and other organizations in the region is working together on this multi-year action plan. Using a broad range of tools and capabilities, we seek to provide long-term, habitat-based solutions for the most pressing challenges for migratory fish. The partnership strives to measure achievement of our mission with the following targets: increased fish populations (as measured by catch-per-unit efforts, improved age structure, and other techniques), increased recreational fishing success for shad, striped bass, and river herring (as measured by creel surveys), and a re-opened striped bass and river herring harvest in the Cape Fear River. The following organizations are members of the Cape Fear River Partnership: American Rivers (AR) Atlantic Coastal Fish Habitat Partnership (ACFHP) Cape Fear Public Utility Authority (CFPUA) Cape Fear River Assembly Cape Fear River Watch (CFRW) City of Wilmington Dial Cordy and Associates Inc.

Schipper Summary Climate change and land use change are ongoing features which affect the hydrological regime by changing the rainfall partitioning into actual evapotranspiration and runoff. A data-based method has been previously developed to attribute changes in streamflow to climate and land use change. Since this method has not been often applied, a large sample attribution study by applying this method to catchments in different parts of the world will provide more insight in the water partitioning and will evaluate the attribution method. The results can be used by water managers of the studied catchments to obtain the main reason for changes in streamflow. The used method is applicable to a large sample set of catchments because it is a relatively fast method and it can provide quantitative results. The objective of this study is to apply a non-modelling attribution method to attribute changes in streamflow to climate change and land use change to a large sample set of catchments in different parts of the world and to evaluate the used method.
