Not all small dams in Authority control are new ones. A number of 

 Authorities have acquired control of old mill dams and surrounding land. 

 Necessary repairs have been carried out on these dams and they fulfil a valuable 

 function of pooling water for the improvement of summer flow and for recreational 

 use. Examples of such dam restoration are the Thornbury Dam on the Beaver 

 River, repaired by the North Grey Region Conservation Authority, and the Credit 

 River Dam at Belfountain, restored by the Credit Authority. 



In many river valleys, flood control can be effectively achieved by public 

 control of the flood plain lands to prevent encroachment and building on the low 

 lying land. Such control is necessary in conjunction with the building of dams 

 and channel improvements. Three Authorities had flood plain land acquisition 

 programs underway in 1962. Flood plain surveys and mapping, necessary pre- 

 liminaries to land acquisition, were carried out in the valleys of several other 

 Authorities.
