     "Slide rock" in north central Arizona is a popular stream on the weekends.
During the terribly hot summer days, hundreds of people (really!) will travel
to the area and (attempt to) cool off in the narrow stream.
     The slide rock portion is a naturally carved flume, three feet wide and
deep, and about thirty or so feet in length.  A ride thru this area is fast,
rough, and cool.  Or at least, it was...
     In recent years, however, pollution of the stream by "human bodies" has
resulted in numerous warnings.  References to "high populations" of various
microscopic organisms are posted on signs in the area, as well as in the local
newspapers.  It is only a matter of time before the health hazard will require
closing of the stream to all.

     Do you know of other streams where a similar "biological" problem exists?
Particularly where scientific measurements and/or reports are available which
document the relative sizes of microscopic populations over several years?
Are there any streams which have "recovered" from this problem?
     Please respond directly to me by mail (electronic).  I will summarize for
the net if enough interest is expressed.
