What is recorded here

Coldblow holds no visible weir, yet the 1837 map still cuts a line across the Liffey between Lucan Demesne and the townland. Beneath that absent line runs a older argument: Hugh de la Felde, Alianora, Robert de Wyleby, John de Hausteyd and Roesia all claimed parts of the same water, while jurors later condemned weirs for starving boats, firewood and fish. The river does not remember their names. It still gives, and men still take what they believe theirs.

According to Went (1954, 51-52) there was a salmon weir granted to Sir William Wyse of Waterfordin Chapelizod in 1524. The Civil survey (1654-6) describes a salmon weir on the river Liffey at Chapelizod (Simington 1945, 223). This was probably associated with the dam formerly used for supplying water to the mills in the area on or close to the present mill dam. No longer used as a fishery except for angling.
