>I am looking for input/helpful suggestions/information from anyone
>who has had experience with a lagoon near a suburban area.  Here in
>San Mateo, CA, we have a lagoon which receives inflow from San
>Francisco Bay and from storm drain outfalls.  All outflow is to the
>Bay.  The lagoon is used for some recreational activities, mostly
>waterskiing and sailboarding.  In response to residents who have
>docks in the lagoon and to preserve the recreational usage, we have
>been treating it for widgeon grass and algae.  So far, we have been
>using Aquazine (simazine), but it is no longer being manufactured.  I
>would love to hear about any non-chemical controls for these two plants
>that have been proven to work well in a similar environment.

>I have heard rumors of an algae research center in London, called
>something like "The Center for Algae Control;" if anyone knows of
>such a place, I am interested in knowing the correct name/address/
>email.

>In addition, we have been noticing an increased number of jellyfish
>in the lagoon.  No stingings have been reported so far, but we are
>worried about the possibility.  Can anyone tell me what might cause a
>surge in jellyfish population (i.e., change in temperature, change in
>salinity, increased inflow from the Bay, etc.), and/or barrier or
>other non-chemical methods which might prevent their contact with
>recreational users of the lagoon.
