Lake Pieman - Bobadil discharge zone biomonitoring report 2012

This report details the 2012 results of a routine annual survey of shore biota in Lake Pieman, based on sampling conducted in autumn (March) 2012. This biological monitoring program aims to assess the ecological status of the area in Lake Pieman influenced by the discharge from the MMG Rosebery mine Bobadil settling pond facility. Previous surveys at this location, including those for the previous operators (Zinifex, Ozminerals), have been reported for spring and autumn every year from 2004/05 to 2008/09 (Davies et al. 2005, 2006a, 2006b, 2007, 2008, 2009, 2010, 2011). The current operator (MMG) is required to report on a single annual survey, so a single autumn sampling was conducted in 2012.
