I forgot to mention--there has not been any habitat manipulation of Beaver 
Lake by park staff that would explain the mudflats.  The new boardwalk along 
the 
north western shore was installed in the summer of 2002 but park officials do 
not believe that the soil was disturbed enough to contribute to the mudflats. 
 The evergreen patches of invasive parrot's feather that are beginning to 
dominate the western side of the lake and threaten the entire lake may prompt 
control measures in the near future.  this plant contributes a lot of 
vegetative 
material to the lake bottom annually (more so than the water lilies and other 
aquatic plants).  --Orcutt
