River was conducted. The biota are highly modified by the historical effects of the
operations of Lake Leake, the modification of the river channel and the introduction

biological values remain, in particular the extensive aquatic plant (macroph yte)
communities and their highly diverse and abundant macroinvertebrate fauna, as well
as the riparian vegetation which is in particularly good condition.
Risks to the instream biota are explored and mitigation requirements identified. A
minimum environmental flow regime and operating rules have been developed.

- integration of management of Lake Leake and the proposed Chimney Hill
Dam;
- ongoing monitoring of the aquatic biological, water quality and
geomorphological condition of the river and storage;
- no major changes to operation of either storage without formal review,

River was conducted. The biota are highly modified by the historical effects of the
operations of Lake Leake, the modification of the river channel and the introduction
of exotic species. The fish community is in a degraded condition. However, key
biological values remain, in particular the extensive aquatic plant (macroph yte)
communities and their highly diverse and abundant macroinvertebrate fauna, as well
as the riparian vegetation which is in particularly good condition.
Risks to the instream biota are explored and mitigation requirements identified. A
minimum environmental flow regime and operating rules have been developed.
Provided the macrophyte assemblages are maintained through appropriate
environmental flow management, there are no significant risks to the aquatic
biological values of the Elizabeth River from the proposed dam.
Key recommendations include:
- implementation of a specific minimum environmental flow regime;
- integration of management of Lake Leake and the proposed Chimney Hill
Dam;
- ongoing monitoring of the aquatic biological, water quality and
geomorphological condition of the river and storage;
- no major changes to operation of either storage without formal review,
especially with regard to potential changes to high/flood flow regime.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Report (Project Report)</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">freswater, Tasmania, environmental flow, dams</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/270701.html">270000 Biological Sciences > 270700 Ecology and Evolution > 270701 Freshwater Ecology</a></td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">689</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">UTas Digital Archives Librarian</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">01 Feb 2007</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">09 Jan 2008 02:30</td></tr><tr><th valign="top" class="ep_row">ePrint Statistics:</th><td valign="top" class="ep_row"><a target="ePrintStats" href="/es/index.php?action=show_detail_eprint;id=689;">View statistics for this ePrint</a></td></tr></table><p align="right">Repository Staff Only: <a href="http://eprints.utas.edu.au/cgi/users/home?screen=EPrint::View&eprintid=689">item control page</a></p>
