This initial development is <br />shown on the map, ligm'e 3. <br />The District will deliver Colorado River water in wholesale <br />quantities to its constituent areas. All retail deliveries will be made <br />to the individual users by the existing water bureaus or depart- <br />ments, or other operating agencies. <br />Although the 1940 population of the member cities is above <br />- . - -2;000,OOO,-the. .potential- service area .cmnprises all-of -tlie- coastal <br />plain with a constantly growing population which now numbers <br />more thau 3,000,000. Estimated future demands for water and <br />rates of increase of demand require a degree of flexibility in the <br />present distribution system, therefore tile plan for development of <br />the distribution system contemplates building in progressive stages <br />with essential portions, adequate for several years, built at first <br />and additional units constnicted as required. . ' <br /> <br />Opemtion Ch"1'acteristics <br /> <br />In the preliminary studies of the location and design of the iuitial <br />distribution system, the water systems of the member cities were <br />examined and data collected concerning points of delivery, desired <br /> <br />[ 61 ] <br />
