Report on water resources of the state and their development.

This report is divided into several parts. The first is a summary of the overall report. The second deals with water supply conditions and shows that 2,070,000 people in the Metropolitan District are supplied with 244 mgd. (million gallons per day) of water by thirty-three separate water works systems, and that the maintainable capacity of the sources now in use is estimated ·at 268 mgd. The margin of 24 mgd. is too small for safety. The third contains a study of past and future growth in population and water consumption. Only time will tell what future growth will be; but it is considered prudent to provide for the needs of a population of 5,6oo,ooo in the Metropolitan District in 1970. The quantity of water then to be provided from public water supply systems is estimated at 820 mgd. In the fourth part are recorded the principal catchment areas now used, and those available for future use of the District, with certain statistics in regard to each, and to the reservoirs necessary to control them. The Morris Canal is mentioned as controlling water rights that might be developed for water supply if navigation were abandoned; but the rights controlled are not large enough to make this a matter of first importance in the general problem. The fifth part describes in general terms the works considered suitable for developing the principal possible sources of water supply
