COMPILATION OF WATER POWER REPORTS 649 



II. Summary of Report 



All the essential features of the report should be brought to- 

 gether here, in a brief statement forming a concise summary of 

 the whole, tabulation of results being made where possible. 



III. General Introductory 



This section should cover the general features of the situation 

 being investigated. This involves a general description of the 

 river and its characteristics, and of the basin as a whole, touching 

 on drainage area, source, direction, drop, falls, rapids, banks, 

 river bed, tributaries, lakes, muskegs, swamps, forest, cultivation 

 along banks, settlements, glaciers, general topographical and 

 geological features, etc., and giving the definite location of the 

 site under study. 



IV. Water Supply 



(1) General Description of Drainage Area. Under general 

 description of the drainage area those features should be dealf" 

 with which are of direct importance to the question of the water 

 supply, such as probability of sudden floods, influence of the sea- 

 sons, etc. 



(2) Run-off Records. If the site inspected is situated on one 

 of the rivers covered by any of the systematic stream measurement 

 work carried on by the department, the existing records should 

 be utilized as a basis upon which the run-off may be discussed. 

 A summary of the essential features of the dischan . ing 

 high, low and mean flow, etc., should be inserted, while the records 

 in their complete form should be attached as appendices in Section 

 XI of the report. Where no records have been taken on the river, 

 estimates or measurements of the flow at the time of the inspection 

 should be made, either by meter or by whatever method of stream 

 measurement is most applicable or convenient. From this, in 

 conjunction with high- water marks in evidence and from the tes- 

 timony of local inhabitants as to extreme low- and high-water 

 conditions, and from a study of the run-off conditions of streams 

 in the vicinity, as careful an estimate as is possible should be made 

 of the extreme low- and high-water conditions on the river, also 

 of the average low and high flows which may be expected. With 

 these data, the months and seasons in which the above conditions 

 are usually in evidence, must be given.
