[1] The Laver is noted as a fly fishing river, especially for brown trout and grayling.

[2] The river has its origins in a number of small streams which rise on the moors between upper Nidderdale and Kirkby Malzeard.

[3] The riverbanks again become densely wooded near Winksley, then become more open and shallow as the river approaches Ripon.

[4] The flow of the River Laver has been measured at a weir in Ripon, near to its confluence with the Skell since 1977.

The thirty seven year record shows that the catchment of 88 square kilometres (34 sq mi) to the gauging station yields an average flow of 1.1 cubic metres per second (39 cu ft/s).
