Each of these sites corresponds to a detailed satellite overview provided
in the following pages.
Criteria for selecting the sites included, (a) areas of successful previous
treatment (b) areas of
high population that have severe weed infestation (c) treatment within each
of the five (5)
surrounding counties as fairly apportioned as possible and (d) areas of public
use and public
access, including public boat ramps, public swim areas and dry hydrants. The
table below lists
each site and the associated acreage.

Estimated 2007 Lake Gaston Weed Control Council Budget
Professional Lake Management based estimates for budget income and expenses
on the most current
information available from Lake Gaston Weed Control Council. Treatment site
acreages and chemical
usage calculations were used to determine the cost of herbicide applications
in addition to vegetations
surveys, monitoring, site assesments, Grass Carp, and various other line items
indicated below.
Herbicide treatments are based on a three applications of granular and/or
liquid herbicides to each of
the sites listed in this document. The sites and methods have been reviewed
and approved by the
Lake Gaston Technical Advisory Committee.
