I'd like to hear of any Australian or overseas projects aimed
specifically at the removal of nutrients from surface waters through
the harvesting of Aquatic Plants.
Many Australian streams and water supply reservoirs are subject to
periodic blue-green algal blooms, creating a major crisis when
drinking water supplies are threatened.
Clearer reservoir waters usually support submerged and emergent
species, whereas many inland streams are restricted to floating plants
due to light exclusion.
Reduction of the harvested plants to provide a commercially useable
liquid fertiliser or any other products would be an advantage.
I would be grateful to receive any replies through this Group.

CALL  FOR  PAPERS
	9th  WORKSHOP  ON  RIVER  ICE
	September 24 - 26, 1997
	Lord Beaverbrook Hotel
	Fredericton, New Brunswick, Canada
The 9th Workshop on River Ice will be held in Fredericton, New
Brunswick, from September 24 to 26, 1997.  The Workshop is sponsored by
the Canadian Committee on River Ice Processes and the Environment, which
is affiliated with the Hydrology Section of the Canadian Geophysical
Union.  The Canadian Society for Civil Engineering is a co-sponsor of
the Workshop.  
The 9th Workshop on River Ice will build upon the 1995 Workshop held in
Kamloops by focusing on the interrelationship between hydro-power
development and river ice regimes.  The general theme for the 9th
Workshop is:
	HYDRO-POWER & ICE-COVERED RIVERS
	Design, Operational and Environmental Considerations
Papers are invited on a broad range of topics related to river ice
engineering and science, including environmental and ecological
conditions in ice-covered rivers.
Topics directly related to the general theme include:
	- Design and construction considerations,
	- Ice processes in regulated rivers,
	- Operational problems and their mitigation and solution, and
	- Ecology and biochemistry in reservoirs.
Other topics to be considered include, but are not limited to, the
following:
	- Effects of climate change on river ice regimes,
	- Breakup forecasting, 
	- Ice jams,
	- Ice forces on structures,
	- Sediment transport in ice-covered rivers, and
	- Ice in estuaries.
Authors are requested to submit an abstract of about 500 words by
January 17, 1997 to:
	Dr. Sayed Ismail, P.Eng, Chairperson
	Technical Program Subcommittee for the
	9th Workshop on River Ice
	c/o New Brunswick Power Corporation
	244 Connell Street
	Woodstock, New Brunswick   E0J 2B0
	Telephone Number: (506) 325-7816	
	Fax Number: (506) 325-5013      
Authors will be notified of the acceptance of their abstracts by
February 14, 1997.  Authors of accepted abstracts should provide a
formal paper to be published in the Workshop Proceedings.  Since the 
Proceedings will be pre-published and provided to attendees at
registration, papers are required in camera-ready format by June 13,
1997.
