Abstract

This report describes the results of the 2009/10 reporting year monitoring of benthic macroinvertebrates and fish in the Meander River, as required under the Meander Dam Water Monitoring Program (DPIWE 2007). This program describes monitoring activities required to comply with conditions endorsed on the Water Licence and Environmental Protection Notice (EPN) No. 7345/1 issued for the operation of the Meander Dam.
Benthic macroinvertebrate sampling was conducted once in spring (November) 2009 and once in autumn (March) 2010, using the AUSRIVAS protocol. Sampling was conducted in riffle habitat at five sites: three sites downstream of Meander Dam, and at two reference sites, one upstream of Huntsman’s Lake, and one in the lower reaches of Jackeys Creek.
The resulting data have been used to derive AUSRIVAS O/E (observed over excepted) scores and impairment bands. These results are compared with similar data collected at the same sites using the same sampling protocol by DPIW (DPIWE 2008) from 1994 to 2008 - prior to and during dam construction. A more detailed description of pre- vs post-dam trends and differences is provided by Davies et al. (2009).
Sampling was also conducted for riverine fish, once in autumn (March 2010) at one site upstream and downstream of Meander Dam, following a request to add fish monitoring to the program by the Irrigation Development Board in early 2010. Fish data were compared to data collected using a similar sampling protocol by DPIW (DPIWE 2008) from 1994 to 2008
