Spotlight Hits Unsavory Subject
  It’s now okay to discuss septic systems and new options for addressing a messy
issue.  This article talks about an artificial wetland that has been constructed
near Grand Lake, MN.

Our Lake Has Fleas
	  Lake Superior is swarming with fleas.  At least 36 species of cladocerans, or
waterfleas, reproduce in the lake and it looks like a 37th is on its way.

"Bone-Cold Cafe" Suits Ruffe
	  A Sea Grant study has shown that the Eurasian ruffe’s metabolism enables this
invasive fish to thrive in the cool water of the St. Louis River.  The study 
also indicates that temperature affects the growth of ruffe less than yellow 
perch but that ruffe need more food than perch to survive.   

New Research Project Funded
	  We are funding a new project that seeks to solve a dilemma facing sewage 
treatment facilities across the Great Lakes and coastal marine areas:  what is 
the best way to treat combined industrial and municipal wastes?  

Staff Update
  	We wrote the best darn news release in the whole darn county in 1998 as a 
government-related organization.  See what committees we are on, where we've 
moved due to "sick building" syndrome, and learn who our new interns are.

Stop Exotics, Clean Your Boat Video
  	Exotics like zebra mussels, Eurasian watermilfoil, and hydrilla are just a 
few aquatic nuisance species that watercraft users can spread if they’re not 
careful. "Stop Exotics, Clean Your Boat" shows the simple steps boaters across 
North America can take to prevent the spread of these nasty plants and animals. 
This 11-minute video features John Ratzenberger (better known as Cliff Clavin 
from the TV show "Cheers"). 

Minnesota Lakes Public Meetings Report
   This is a free 37-page report  that summarizes results from a roundtable 
meeting and public workshops held in 1998.  The meeting and workshops focused on
the health of lakes in northeastern Minnesota and were held to define issues and
develop strategies to prevent lake deterioration.  It's called "Treasures Under 
Pressure—The Future of Northeastern Minnesota Lakes."

I wonder how much deeper the ocean would be without sponges?
