Show THE ALLrAMERICAN CANAL. 97 POWER DEVELOPMENT. (a) Plans are made for a temporary or construction power plant at or near Pilot Knob, where a drop of about 30 feet can be obtained by discharging the water into the Imperial Canal. This power plant should be constructed and made available for the generation of power at as early a date as possible in order to furnish cheap power for construction purposes. The plans are for the development of two units of 4,500 turbine horsepower each, with provision for adding a third unit of the same size. In the preliminary report the temporary power plant was located at the lower or south end of the rock cut at Pilot Knob. Since that report was made another site nearly opposite the Rockwood gate has also been investigated. Test pits at both sites have been put down as deep as possible without resorting to pumping of the water. The tailrace of the upper one of these sites would discharge into the Imperial Canal between the Roekwood and Hanlon gates. The tailrace from the lower site will discharge into the Imperial Canal below Hanlon gate. It is as yet a question which of these sites should be developed. If developed at the upper site and a siphon spillway used to regulate the flow in conjunction with the power house and later a sluice gate located at the lower power site were constructed, considerable heavy construction work would be avoided until after the upper portion of the system could be placed in operation and electric power generated. This would give an estimated expenditure of $4,880,258 for canal construction from Laguna Dam after deducting the following items from the first three items under "Recapitulation" (p. 89): Cost of connecting \rith Laguna Dam......................_____.......___. .$1,900,000 Sluiceway and check..................----............................. 347,000 15 pea: cent contingency on above...........-................,........ 52,050 Total deduction................................................ 2,299,05Q To which should be added: .

(6) West of the sand hills there are two drops where it is planned to develop power. These we have called power plant No. 1 and power plant No. 2. (c) At power plant No. 1, which is located 4 miles west of the east-side mesa canal, there is a fall of 24 feet. Three miles east of this power site there is a drop of 6 feet, which may in the future be carried downstream to power plant No. 1 by raising the canal 149799-20------7 |
