DIVISION OF SURVEYS AND ENGINEERING 



The primary requirements of any attempt of the intelligent use of our natural 

 resources and to solve the problem of the proper use of land and water is to have 

 available accurate maps showing topography, drainage systems, types of soil and 

 mineral resources. These maps make possible accurate description of the location 

 of places or areas to be served. It is impossible to estimate the value of proper maps 

 and aerial photographs to both Government agencies and industry and their value 

 is many times their cost. 



Through the arrangement made with the Army Survey Establishment of the 

 Department of National Defence, four more sheets of the National Topographical 

 Map Series, on a scale of two miles to an inch, have been completed and provisional 

 prints of live other sheets are being checked before being printed. These maps may 

 be obtained through this Department at nominal charges. During this year, 2,250 

 of these maps were issued, being an increase of over 300 '^'r over the previous year. 



During this year, power developments at Des Joachims and the Chenaux on 

 the Ottawa River, Pine Portage on the Nipigon River and the Tunnel Development 

 on the Mississagi River, were completed. The total installed capacity of these plants 

 will be 776.000 horsepower. This will increase the revenue derived from water power 

 rental by a substantial amount. 



The number of parcels of Crown Lands surveyed for summer resort locations 

 was again increased The surveys of 1.737 parcels were completed, the plans 

 examined and checked and descriptions prepared so that patents could be issued. 

 This additional work made it necessary to increase the number employed both on 

 the field work and in the office staff. Marked progress has been made in meeting 

 the back-log of applications for resort parcels created during the post war period. 

 The Department used a survey party composed of members of its own staff on this 

 type of work. 



Space was secured in part for a pre-fabricated quonset hut for storage space 

 for survey equipment and miscellaneous and survey and engineering plans. This 

 hut was constructed by the Department of Public Works at the Research Station, 

 Maple, Ontario. 



The necessary legislation having been passed by both of the Provincial and 

 the Federal Parliaments to accept the boundary between the Provinces of Ontario 

 and Manitoba, as surveyed on the ground from Island Lake to Hudson's Bay, 

 arrangements were made to have permanent monuments established along this 

 boundary. An inspection was made of these monuments and the report of the 

 Boundary Commissioners is being prepared. 



The portion of the photography and mapping, undertaken by the Aerial 

 Surveys Section of this Division, as part of the Forest Resources Inventory, having 

 been nearly completed, there was less amount of this type of work carried out during 

 the year. The members of the staff of that Section were used to prepare soil maps 

 for the Research Division and also, to prepare new maps showing additional 

 information obtained from the planimetric maps for townships that had not been 

 subdivided and where only the township outlines had been surveyed. This Section 

 will continue to photograph and map additional areas in the western part of the
