P. in tv;c additional months, but perhaps only 40 to 60H. P. in one month, usually August. However, Augustis the time when peper mills usually shut down forrepairs. Of course with the reservoir built affording100 foot head or mere and regulating the flow, thispower will produce probably 1000 H. P. or more ofcontinuous I understand, however, you are notfiguring on developing storage at present. I would suggest a concrete dam of about theform shown in the sketch This must be well anchored into rock by ironpins and should be set back far enough from thecrest of the upper falls to prevent darasite is very favorable as you will see from the accompanying photo. I would suggest a 4 footdiameter penstock and two turbines each of about 30cubic feet per second capacity in horizontal cost of development would be roughly as follov/s;Concrete dam 200 long ----- |1400Intake, racks and head gates - - - 3504 steel penstock 1300 long - - - 6500Two turbines in steel cases, erected 1000Standpipe, penstock anchorage, etc. - 250Tail race excavation, etc. - - - _ 500 Total -llOOOOAdd contingencies, etc. - - - - |11500The cost of the penstock could probably be re-duced by using wood stave pipe, but the steel pipeand turbines proposed here would be adapted alse tothe higher head development. This development would produce an average of250 net H. P. and is an exceedingly low cost
