The farther downstream control structures could be placed and operated in these and connecting cankls which discharge into salt water, the more effective water control w6oid become, and the closer to the Bay the encroaching salt water would be feld. SURFACE WATER SUPPLIES IN SOUTHEASTERN FLORIDA There are briefly described below, from the standpoint of quantity and quality, the several surface water sources in southeastern Florida that might be considered as possible future supplies for the Miami area. The brief evaluation of these sources does not include the economics of development other than reference to their distances from the point of utilization. A certain potential source of supply may, because of its remoteness, be considered impracticable for early development but may, owing to greatly increased population and water consumption, be an entirely feasible supply in the distant future. KISSIMMEE RIVER This is the most distant of all sources covered in this report, the mouth of the Kissimmee River being nearly 100 airline miles from Miami and a. considerably longer distance by any practicable water-conduit route. The quantity of water available from the Kissinzee River is best determined from the discharge as measured since 1928 at a gaging station near the point
