NATIONAL FOREST MANUAL. 15 



elevations, and cross sections of each type of water conduit, showing 

 material, dimensions, grades, flow line, and capacity and plans and 

 elevations of intake works and fore bays. 



(3) A contour map on a scale of not more than 50 feet to the inch, 

 with a contour interval of not more than 5 feet, showing the proposed 

 location of the power house, other buildings, etc., shall be filed for 

 each power-house site that will be a part of the power project OP 

 projects applied for. This map shall also state the proposed type 

 and estimated number and rated capacity of the water wheels and 

 generators to be used. 



(4) A map of the survey of the proposed final location of the 

 center line of the transmission line, on a scale of not more than 

 1,000 feet to the inch, shall be filed for such portions of transmission 

 lines as are located upon National Forest lands. 



(5) A general map of the entire power project or projects applied 

 for (except transmission lines), on such a scale that the entire survey 

 may be shown upon a single sheet; also a similar map showing the 

 entire primary transmission system. 



(F) Copies of field notes in triplicate of the entire final location 

 survey of water conduits, and transmission lines, the exterior bound- 

 aries of power-house and reservoir sites, and all reference lines to 

 public-land corners. 



(G) Estimates in triplicate for each power project of (1) the total 

 average effective head to be utilized, and the per cent thereof to be 

 obtained from dam and from water conduit, respectively; (2) the 

 stream flow, and the per cent thereof made available from storage 

 by the project works and by other works, respectively; (3) the area 

 to be flooded by the dam below the flow line fixed by the estimated 

 average effective head ; (4) the length of the proposed water conduit 

 (from intake to tailrace outlet) ; (5) the area and available capacity 

 of each proposed storage reservoir; (6) the available storage capacity 

 of fore bays (or diversion pond) ; (7) the probable load factor of the 

 power system, and (8) the distances in miles of primary transmission. 



These estimates should be accompanied by complete statements in 

 detail of all data on which they are based, including stream measure- 

 ments, rainfall, stream flow, and evaporation records, drainage areas, 

 total static head and losses in head, probable maximum, minimum, 

 and average power output, load curves of the power system, effi- 

 ciencies of machinery, probable points of delivery of power, and all 

 other pertinent information. 



(H) Such evidence of water appropriation as is specified in Regu- 

 lation L-10 (G). If such evidence has been filed with an application 

 for a premliminary permit, only such additional evidence, in general, 

 will be required as will cover appropriations or transfers subsequent 

 to the date of the evidence filed with the application for preliminary 

 permit. But wherever the approval of a local administrative board 

 or commission is a condition precedent to the right either to take and 

 use water for power purposes or to engage in the business of the 

 generation, transmission, or distribution of power, certified evidence 

 of such approval must also be filed with the application for final 

 permit. 



(I) A detailed statement in triplicate by the applicant of the time 

 desired for making financial arrangements, for completing prelimi-
