SEC. 11. SIMULATION MODEL OF SOUTH CENTRAL FLORIDA HYDRO-
LOGIC ECOSYSTEM.

(a) IN GENERAL.—The Secretary, in cooperation with affected
Federal, State, and local agencies and other interested persons, may
develop and operate a simulation model of the central and southern

cantly affect the ecology of such ecosystem,

on the flow, characteristics, quality, and quantity of surface and
ground water in such ecosystem and on plants and wildlife within

and operating the simulation model under this section shall be 75
percent.
