654 ECONOMICAL ASPECTS 



floor of generator room, tail- water, etc., should also be obtained 

 in the best manner which circumstances may dictate. 

 Profiles of any pipe or canal lines are also required. 



(4) Foundation Conditions. Full note should be made of the 

 natural conditions of the ground and river bed at the proposed 

 dam and power-house site. If there is rock in sight a full state- 

 ment of its character, weathering qualities, etc., is required. If 

 no rock is in evidence as careful an investigation of the existing 

 conditions as circumstances permit is required. 



(5) Flooding and Pondage. The direct flooding which will be 

 caused by the construction of the proposed or any feasible plant 

 at the site should be determined approximately either by inspec- 

 tion or if necessary by, rough instrument work. If the land has 

 been surveyed the flooded portion can be listed by sections and 

 quarter sections. 



The utilization of this local pondage in connection with peak 

 loads at the project plant should receive general consideration. 



(6) Existing Interests. All existing interests, such as bridges, 

 trails, roads, railways, buildings, etc., that may be affected by the 

 construction of the plant and by the consequent flooding, should 

 be fully reported on. The question of the logging and fishing 

 interests on the river should be discussed in considerable detail. 



VII. Possible Power Developed 



The question of power possible of development should be dis- 

 cussed from the standpoints of, first, no storage available, and 

 second, storage available. Under the first head the power avail- 

 able at minimum flow and the power which might be developed 

 during the eight or nine months not included in the extreme low- 

 water season should be covered. 



Under both headings the beneficial utilization of the local 

 pondage for peak loads and the consequent increased power out- 

 put should be dealt with. 



VIII. Estimates 



Approximate estimates of the capital and annual operating 

 costs of the proposed scheme of development and the basis on 

 which these are made should accompany the report, together with 

 similar estimates of the cost of any proposed storage reservoirs.
