lack of correspondence between Matawhara, at the east end of the 

 lake, and the deep water which lies some distance to the west of it. 



The two lakes Taupo and Eotoiti have in common a tank-like form 

 of basin. It is also possible that a relation between the two may be 

 indicated by the presence in each of isolated banks or shoals. Examples 

 of such shoals are found in the west end of Eotoiti, and in Taupo 

 between Karangahape and the island Motutaiko. 



The remaining lakes form a very heterogeneous lot. Kotorua is a 

 saucer-like depression, a mere continuation .of the whole catchment 

 basin in which it lies, regular in its outline and in its subaqueous slopes. 

 It can not be compared to the more abrupt and tank-like lakes among 

 which it lies, though it may possibly have with them a common origin 

 in subsidence, similar but less violent.

Waikarc and WhaDgape are so shallow as to rank rather with 

 swamps than with lakes, in spite of their considerable area. The 

 interest of the former lies chiefly in its peculiar relation to the Waikato 

 river, a relation which enables it to reduce the harmful effects of floods, 

 though not lying on the river's actual course.
