This station was originally established by the United States 

 Engineer Corps ; readings are now taken by the United States 

 Weather Bureau. The gage, which is attached to the iron 

 highway bridge, the floor of which is about 60 feet above low 

 water, is in two sections. The lower section, which reads from 

 0.3 feet to -(-2.30 feet, is secured to the pile on the lower 

 side of the cofferdam on the draw pier ; the upper section, which 

 reads from 2 . 30 feet to 48 feet, is spiked to the highway bridge. 

 The bench mark, which is an iron bolt driven into the face of a 

 rock bluff 182.3 feet from the first bridge pier, on the road as- 

 cending to the city, is 26 feet above the zero of the gage and 

 87.30 feet above mean sea level. The top of the coping stone 

 of the pivot pier at -the highway bridge to which gage is at- 

 tached is 56 feet above the zero of the gage, and 117.30 feet 

 above mean sea level. Graduations extend from 3.0 feet to 

 -(-48 feet. No measurements of discharge were made here 

 during 1899.
