MEMORANDUM

TO: W. T. Allee, Assistant to the Executive Director
FROM: W. B. Smith, Hydrologist, Resource Regulation Departent
RE: Basin Boundaries
The Resource Regulation Staff has recently reviewed the matter of groundwater
basin identifications and found them subject to the effects of climate and
water uses which cause movements of groundwater divides. ThneefP e, further
study of groundwater basins will be necessary to determine if they could be
used to aid in re-definitions of our river ba4ts. At this time there does
not appear to be any feasil6e way of employing groundater basins for regula-
tory purposes.
With respect to surface water basins and basin divides, the total water manage-
ment faction may require adjustments however, no concrete proposal can be
forwarded at this time. These future considerations relatqto uniting all
surface water and watertable aquifer units with the underlying artesian aquifers
they supply and placing the under a single administrative organization where
possible.
Some general changes which might be considered are merging Northwest Htllsborough
and the Pinellas-Anclote Basins, exclusive of the peninsula south of S.R. 584.
The southern area should be set up as a separate hydrologic unit. Several
adjustments are needed along the Myakka, Horse Creek, Little Manatee and Five
Mile Creek drainage systems to contain them under a single basin.
