The Water Supply Commission believes that the possibilities for small water powers should be pointed out to the people of the State in order that there may be a better realization of the usefulness and value of this remarkable natural resource and that the farmers and residents of rural districts may take advantage of the opportunities to conserve and utilize them. It is believed that some facts relating to the utility of power in general and small water powers in particular, together with descriptions of some typical small water-power developments that are now in actual operation, and brief notes as to how such a power may be developed and applied, will suffice to bring the subject forcibly to the attention of those most interested, and furnish at least a beginning for observations in this comparatively new field, and stimulate a tendency to a more general utilization of this source of power, and a consequent saving of much energy now secured from coal, wood and other exhaustible producers of power. Accordingly, the following discussion of the many and varied uses for power on the modern farm, together with descriptions of developments now in use, and notes on developing a small water power, are submitted in the hope that they may be of interest and service to those who have chosen farming for their livelihood or pleasure, especially by assisting them in the consideration as to whether or not it may be worth while to develop the power of any particular stream. These discussions and descriptions are not intended to suffice as a practical handbook for laying out a power plant, but merely to point the way to an intelligent consideration of the possibilities, by showing what others have done and laying down a few fundamental principles, which should properly be taken into consideration in determining upon the development of a small water power.
