Specific information relative to the sea lamprey runs in Carp 

 Creek and the Ocqueoc River in several years (presented by stream 

 and by year) is as follows: 



Carp Creek , 19h7:— The earliest migrants observed at Carp Creek 

 were four individuals seen by the writer between 11:00 and 12:00 

 P. M. on the night of April lU. These sea lampreys were spotted 

 with the aid of a jack-light about 100 feet offshore on the gravel 

 "fan" which extends from the mouth of Carp Creek into Hammond Bay 

 (Figure lU) . 



During the time they were observed, they made no effort to move 

 up into the creek mouth but clung persistently to the same rock until 

 deliberately frightened by the observers. When frightened, they 

 darted off across, or with, the current and dropped into the deeper 

 waters of the bay. At the time of these observations, the water 

 temperature on the "fan" was 39 degrees F. and the air temperature 

 was 32 degrees F, Floe ice was still present in the bay.
