The number of requests for information concerning the construction 

 of dams on small streams has Increased each year. These dams are construc- 

 ted by owners of properties as suburban homes and creation of ponds to con- 

 serve water for irrigation and farm ponds. Plans of thirteen such dams 

 were examined in addition to fifteen daans for storage and timber operations. 



Eight licences of occupation for flooding were issued and seven 

 licences for flooding were cancelled. 



A new Water Power Lease Agreement was issued to replace a lease 

 which had expired. 



Hydrologic data and information on previous dams were supplied to 

 the Department of Public Works for the construction of three new dams and 

 the rebuilding of seven dams. Inspections of twelve dams were made. The 

 programme of rebuilding obsolete dams formerly used in lumbering operations 

 was continued. 



The reconstruction of the Tarentorus Trout Rearing Station was 

 nearly completed. Reinforced plastic trough were used instead of the 

 former cedar troughs and these have proved to ensure more efficient opera- 

 tion. Pressure filter units with capacity of 300 imperial gallons for use 

 as de chlorinating filters were installed at the Port Arthur hatchery. 

 Plastic valves to replace metal valves to supply hatchery troughs were in- 

 stalled at the Wlarton Hatchery, An old wood stove pipe for the water 

 supply main at the Deer Lake Hatchery was replaced by a smaller asbestos- 

 oement pressxare pipe. Investigations of using more efficient materials 

 used in the construction of all hatcheries are being carried on. Preliminary 

 planning is progressing for a major renovation of the Chatsworth Trout Rear- 

 ing Station.
