REMARKS ON THE FLOOD-TV ATER OF THE WYE. 



During the past summer the river continued unusually low. In April and 

 Blay there were several flushes, but throughout June, July, and August (except 

 on a few days), and up to September 12th, the height of the river varied little 

 from low-water level ; consequently the salmon fishing season in the fresh-wate"^ 

 fisheries has again been an unproductive one. The floods in December have been 

 excessive, though the total height does not equal that of the same month in 1868. 

 The flood of December 19th was 16 feet in height. The only higher floods on 

 record are those of February, 1852, 18 feet 4 inches, and of February 11th, 1795, 

 20 feet. 



Mr. Curley, C. E. , has from careful measurements prepared a table showing 

 the number of cubic feet of water passing down per minute, at each foot of 

 height up to 10 feet, and thus it will be easy to compute approximately the 

 quantity of water flowing down the Wye in the year. This table is now placed 

 on the pier of the bridge by the side of the register-plate— a copy is also 

 Bubjoined. Steps are being taken by one of the members to ascertain the amount 

 of sediment in flood-water. Tables of the rainfalls at three different stations in 

 the upper valley of the Wye are given, as well as that of the rainfall at Hereford.
