>  Robert,
 
     In regards to weed harvesting, this may have to be done 2 times per
year.  Since the areas are shallow the water level may have to be
raised in order to float the loaded harvester.  One advantage of the
shallow waters is that the cutter bar on the harvester should be able
to cut just above the hydrosoil.  The hydrosoil is the layer of
sediment that comes in contact with the water.   By cutting the
plants this close to the hydrosoil the regrowth of the plants may be
inhibited.
     AAI will supply our larger weed harvester for the lakes and also
supply our shore conveyor.  The harvested weeds will be directly
unloaded onto the shore conveyor and then the harvested weeds will
travel on the shore conveyor and fall into the bed of a dump truck.. 
The truck and disposal site should be supplied by your town.  If they
do not have a dumptruck we can supply one.
We will also need an access point to launch the harvester into the lakes.
The water depth should be at least 3 ft. deep to launch the harvester.
     The advantages of harvesting are: no permits are needed,  no
herbicides are used to control the weeds, can be selective on areas
to harvest, removal of biomass and nutrients incorporated in weeds,
quick results.  Disadvantages of harvesting, may have to be done more
than once/yr., need a disposal site for harvested weeds, need a lauch
site, may take several weeks to do both lakes.
     Costs for this will range between 15-30,000 for both lakes.
     Hydroraking or rototilling should be done after the first year.  AAI
should gain some experience on these lakes first to evaluate the
results of the proposed harvesting. In order to hydrorake NYDEC
permits are required and costs range in the permits of
$3,000.-$4,000. depending on the amount of meetings set with DEC. 
Permit processing times range from 90 days to 6 months to get
approved.
     AAI has a hydroraking video on youtube,  go to youtube, and search
for hydroraking and video will come up. Best Regards, Larry Kovar
