Figure 19.--Schematic illustration of elevations and ranges of water levels in the high pool, 

 low pool, and outside areas for spring, mean, and neap tides. 



Water levels 



The mean level of the high pool will be 

 raised about 6 feet with a tidal range 

 averaging 4 feet. Minimum and maximum 

 ranges will be Z\ and 4j feet. Mini- 

 mum elevation, which will occur during 

 neap tides, and maximum elevation, 

 which will occur during spring tides, 

 will be 3 feet and 11 feet above mean 

 sea level. 



The mean level of the low pool will be 

 lowered 5 feet with a "tidal" range 



averaging 8 feet. Minimum and maximum 

 ranges will be 5^ and 9j feet respec- 

 tively. Maximum elevation, which will 

 occur during mean tides, and mini- 

 mum elevation, which will occur during 

 spring tides, will be zero and -11 feet 

 respectively relative to mean sea level. 



Due to configuration, the tidal range 

 of the Bay of Fundy may increase approx- 

 imately 1 percent. The increase in maxi- 

 mum range will occur at the head of the 

 Bayof Fundy and should be less than 1 foot.
